Inside the Patient-Oncologist Bond: Why It’s Often So Strong
Rose Gerber was 39, mother to a third grader and a kindergartener, when the diagnosis came: Advanced HER2-positive breast cancer.
“On one of my first or second appointments, I took in a little picture of Alexander and Isabella,” Gerber said. Gerber showed her oncologist the picture and told her: “I’ll do anything. I just want to be there for them.”
That was 21 years ago. Today, her current cancer status is “no evidence of disease.”
Over the past 2 decades, Gerber has gotten to be there for her children. Her youngest is now a television producer and her oldest, a CPA.
In that time,
“I’ve seen multiple physicians over my 21 years, but my oncologist has always been the focal point, guiding me in the right direction,” Gerber said in an interview.
Over the years, Jaga guided Gerber through a range of treatment decisions, including a Herceptin clinical trial that the mom of two views as lifesaving. Jaga often took on the role of both doctor and therapist, even providing comfort in the smaller moments when Gerber would fret about her weight gain.
The oncologist-patient “bond is very, very, very special,” said Gerber, who now works as director of patient advocacy and education at the Community Oncology Alliance.
Gerber isn’t alone in calling out the depth of the oncologist-patient bond.
Over years, sometimes decades, patients and oncologists can experience a whole world together: The treatment successes, relapses, uncertainties, and tough calls. As a result, a deep therapeutic alliance often develops. And with each new hurdle or decision, that collaborative, human connection between doctor and patient continues to form new layers.
“It’s like a shared bonding experience over trauma, like strangers trapped on a subway and then we get out, and we’re now on the other side, celebrating together,” said Saad Khan, MD, an associate professor of medicine (oncology) at Stanford University in California.
Connecting Through Stress
Although studies exploring the oncologist-patient bond are limited, some research suggests that a strong therapeutic alliance between patients and oncologists not only provides a foundation for quality care but can also help improve patients’ quality of life, protect against suicidal ideation, and increase treatment adherence.
Because of how stressful and frightening a cancer diagnosis can be, creating “a trusting, uninterrupted, almost sacred environment for them” is paramount for Khan. “I have no doubt that the most important part of their treatment is that they find an oncologist in whom they have total confidence,” Khan wrote in a blog.
The stress that patients with cancer experience is well documented, but oncologists take on a lot themselves and can also experience intense stress (.
“I consider my patient’s battles to be my battles,” Khan wrote.
The stress can start with the daily schedule. Oncologists often have a high volume of patients and tend to spend more time with each individual than most.
According to a 2023 survey, oncologists see about 68 patients a week, on average, but some oncologists, like Khan, have many more. Khan typically sees 20-30 patients a day and continues to care for many over years.
The survey also found that oncologists tend to spend a lot of time with their patients. Compared with other physicians, oncologists are two times more likely to spend at least 25 minutes with each patient.
With this kind of patient volume and time, Khan said, “you’re going to be exhausted.”
What can compound the exhaustion are the occasions oncologists need to deliver bad news — this treatment isn’t working, your cancer has come roaring back and, perhaps the hardest, we have no therapeutic options left. The end-of-life conversations, in particular, can be heartbreaking, especially when a patient is young and not ready to stop trying.
“It can be hard for doctors to discuss the end of life,” Don Dizon, MD, director of the Pelvic Malignancies Program at Lifespan Cancer Institute and director of Medical Oncology at Rhode Island Hospital, Providence, wrote in a column in 2023. Instead, it can be tempting and is often easier to focus on the next treatment, “instilling hope that there’s more that can be done,” even if doing more will only do harm.
In the face of these challenging decisions, growing a personal connection with patients over time can help keep oncologists going.
“We’re not just chemotherapy salesmen,” Khan said in an interview. “We get to know their social support network, who’s going to be driving them [to and from appointments], where they go on vacation, their cat’s name, who their neighbors are.”
A ‘Special Relationship’
Ralph V. Boccia, MD, is often asked what he does.
The next question that often comes — “Why do I do what I do?” — is Boccia’s favorite.
“Someone needs to take these patients through their journey,” Boccia, the founder of The Center for Cancer and Blood Disorders, Bethesda, Maryland, typically responds. He also often notes that “it is a special relationship you develop with the patient and their families.”
Boccia thinks about one long-term patient who captures this bond.
Joan Pinson, 70, was diagnosed with multiple myeloma about 25 years ago, when patients’ average survival was about 4 years.
Over a quarter century, Pinson has pivoted to different treatments, amid multiple relapses and remissions. Throughout most of this cancer journey, Boccia has been her primary oncologist, performing a stem cell transplant in 2000 and steering her to six clinical trials.
Her last relapse was 2 years ago, and since then she has been doing well on oral chemotherapy.
“Every time I relapsed, by the next appointment, he’d say, ‘here is what we are going to do,’ ” Pinson recalled. “I never worried, I never panicked. I knew he would take care of me.”
Over the years, Pinson and Boccia have shared many personal moments, sometimes by accident. One special moment happened early on in Pinson’s cancer journey. During an appointment, Boccia had “one ear to the phone” as his wife was about to deliver their first baby, Pinson recalled.
Later, Pinson met that child as a young man working in Boccia’s lab. She has also met Boccia’s wife, a nurse, when she filled in one day in the chemotherapy room.
Boccia now also treats Pinson’s husband who has prostate cancer, and he ruled out cancer when Pinson’s son, now in his 40s, had some worrisome symptoms.
More than 2 decades ago, Pinson told Boccia her goal was to see her youngest child graduate from high school. Now, six grandsons later, she has lived far beyond that goal.
“He has kept me alive,” said Pinson.
The Dying Patient
Harsha Vyas, MD, FACP, remembers the first encounter his office had with a 29-year-old woman referred with a diagnosis of stage IV breast cancer.
After just 15 minutes in the waiting room, the woman announced she was leaving. Although office staff assured the woman that she was next, the patient walked out.
Several months later, Vyas was called for an inpatient consult. It was the same woman.
Her lungs were full of fluid, and she was struggling to breathe, said Vyas, president and CEO of the Cancer Center of Middle Georgia, Dublin, and assistant professor at Augusta University in Georgia.
The woman, a single mother, told Vyas about her three young kids at home and asked him, “Doc, do something, please help me,” he recalled.
“Absolutely,” Vyas told her. But he had to be brutally honest about her prognosis and firm that she needed to follow his instructions. “You have a breast cancer I cannot cure,” he said. “All I can do is control the disease.”
From that first day, until the day she died, she came to every appointment and followed the treatment plan Vyas laid out.
For about 2 years, she responded well to treatment. And as the time passed and the trust grew, she began to open up to him. She showed him pictures. She talked about her children and being a mother.
“I’ve got to get my kids in a better place. I’m going to be there for them,” he recalled her saying.
Vyas admired her resourcefulness. She held down a part-time job, working retail and at a local restaurant. She figured out childcare so she could get to her chemotherapy appointments every 3 weeks and manage the copays.
Several years later, when she knew she was approaching the end of her life, she asked Vyas a question that hit hard.
“Doc, I don’t want to die and my kids find me dead. What can we do about it?”
Vyas, who has three daughters, imagined how traumatic this would be for a child. She and Vyas made the shared decision to cease treatment and begin home hospice. When the end was approaching, a hospice worker took over, waiting for bodily functions to cease.
When news of a death comes, “I say a little prayer, it’s almost like a send-off for that soul. That helps me absorb the news ... and let it go.”
But when the bond grows strong over time, as with his patient with breast cancer, Vyas said, “a piece of her is still with me.”
Khan had no relevant disclosures. Boccia and Vyas had no disclosures.

Many Patients With Cancer Visit EDs Before Diagnosis
Researchers examined Institute for Clinical Evaluative Sciences (ICES) data that had been gathered from January 1, 2014, to December 31, 2021. The study focused on patients aged 18 years or older with confirmed primary cancer diagnoses.
Factors associated with an increased likelihood of an ED visit ahead of diagnosis included having certain cancers, living in rural areas, and having less access to primary care, according to study author Keerat Grewal, MD, an emergency physician and clinician scientist at the Schwartz/Reisman Emergency Medicine Institute at Sinai Health in Toronto, Ontario, Canada, and coauthors.
“The ED is a distressing environment for patients to receive a possible cancer diagnosis,” the authors wrote. “Moreover, it is frequently ill equipped to provide ongoing continuity of care, which can lead patients down a poorly defined diagnostic pathway before receiving a confirmed diagnosis based on tissue and a subsequent treatment plan.”
The findings were published online on November 4 in CMAJ).
Neurologic Cancers Prominent
In an interview, Grewal said in an interview that the study reflects her desire as an emergency room physician to understand why so many patients with cancer get the initial reports about their disease from clinicians whom they often have just met for the first time.
Among patients with an ED visit before cancer diagnosis, 51.4% were admitted to hospital from the most recent visit.
Compared with patients with a family physician on whom they could rely for routine care, those who had no outpatient visits (odds ratio [OR], 2.09) or fewer than three outpatient visits (OR, 1.41) in the 6-30 months before cancer diagnosis were more likely to have an ED visit before their cancer diagnosis.
Other factors associated with increased odds of ED use before cancer diagnosis included rurality (OR, 1.15), residence in northern Ontario (northeast region: OR, 1.14 and northwest region: OR, 1.27 vs Toronto region), and living in the most marginalized areas (material resource deprivation: OR, 1.37 and housing stability: OR, 1.09 vs least marginalized area).
The researchers also found that patients with certain cancers were more likely to have sought care in the ED. They compared these cancers with breast cancer, which is often detected through screening.
“Patients with neurologic cancers had extremely high odds of ED use before cancer diagnosis,” the authors wrote. “This is likely because of the emergent nature of presentation, with acute neurologic symptoms such as weakness, confusion, or seizures, which require urgent assessment.” On the other hand, pancreatic, liver, or thoracic cancer can trigger nonspecific symptoms that may be ignored until they reach a crisis level that prompts an ED visit.
The limitations of the study included its inability to identify cancer-related ED visits and its narrow focus on patients in Ontario, according to the researchers. But the use of the ICES databases also allowed researchers access to a broader pool of data than are available in many other cases.
The findings in the new paper echo those of previous research, the authors noted. Research in the United Kingdom found that 24%-31% of cancer diagnoses involved the ED. In addition, a study of people enrolled in the US Medicare program, which serves patients aged 65 years or older, found that 23% were seen in the ED in the 30 days before diagnosis.
‘Unpacking the Data’
The current findings also are consistent with those of an International Cancer Benchmarking Partnership study that was published in 2022 in The Lancet Oncology, said Erika Nicholson, MHS, vice president of cancer systems and innovation at the Canadian Partnership Against Cancer. The latter study analyzed cancer registration and linked hospital admissions data from 14 jurisdictions in Australia, Canada, Denmark, New Zealand, Norway, and the United Kingdom.
“We see similar trends in terms of people visiting EDs and being diagnosed through EDs internationally,” Nicholson said. “We’re working with partners to put in place different strategies to address the challenges” that this phenomenon presents in terms of improving screening and follow-up care.
“Cancer is not one disease, but many diseases,” she said. “They present differently. We’re focused on really unpacking the data and understanding them.”
All this research highlights the need for more services and personnel to address cancer, including people who are trained to help patients cope after getting concerning news through emergency care, she said.
“That means having a system that fully supports you and helps you navigate through that diagnostic process,” Nicholson said. Addressing the added challenges for patients who don’t have secure housing is a special need, she added.
This study was supported by the Canadian Institutes of Health Research (CIHR). Grewal reported receiving grants from CIHR and the Canadian Association of Emergency Physicians. Nicholson reported no relevant financial relationships.

The current findings also are consistent with those of an International Cancer Benchmarking Partnership study that was published in 2022 in The Lancet Oncology, said Erika Nicholson, MHS, vice president of cancer systems and innovation at the Canadian Partnership Against Cancer. The latter study analyzed cancer registration and linked hospital admissions data from 14 jurisdictions in Australia, Canada, Denmark, New Zealand, Norway, and the United Kingdom.
“We see similar trends in terms of people visiting EDs and being diagnosed through EDs internationally,” Nicholson said. “We’re working with partners to put in place different strategies to address the challenges” that this phenomenon presents in terms of improving screening and follow-up care.
“Cancer is not one disease, but many diseases,” she said. “They present differently. We’re focused on really unpacking the data and understanding them.”
All this research highlights the need for more services and personnel to address cancer, including people who are trained to help patients cope after getting concerning news through emergency care, she said.
“That means having a system that fully supports you and helps you navigate through that diagnostic process,” Nicholson said. Addressing the added challenges for patients who don’t have secure housing is a special need, she added.
This study was supported by the Canadian Institutes of Health Research (CIHR). Grewal reported receiving grants from CIHR and the Canadian Association of Emergency Physicians. Nicholson reported no relevant financial relationships.

Researchers examined Institute for Clinical Evaluative Sciences (ICES) data that had been gathered from January 1, 2014, to December 31, 2021. The study focused on patients aged 18 years or older with confirmed primary cancer diagnoses.
Factors associated with an increased likelihood of an ED visit ahead of diagnosis included having certain cancers, living in rural areas, and having less access to primary care, according to study author Keerat Grewal, MD, an emergency physician and clinician scientist at the Schwartz/Reisman Emergency Medicine Institute at Sinai Health in Toronto, Ontario, Canada, and coauthors.
“The ED is a distressing environment for patients to receive a possible cancer diagnosis,” the authors wrote. “Moreover, it is frequently ill equipped to provide ongoing continuity of care, which can lead patients down a poorly defined diagnostic pathway before receiving a confirmed diagnosis based on tissue and a subsequent treatment plan.”
The findings were published online on November 4 in CMAJ).
Neurologic Cancers Prominent
In an interview, Grewal said in an interview that the study reflects her desire as an emergency room physician to understand why so many patients with cancer get the initial reports about their disease from clinicians whom they often have just met for the first time.
Among patients with an ED visit before cancer diagnosis, 51.4% were admitted to hospital from the most recent visit.
Compared with patients with a family physician on whom they could rely for routine care, those who had no outpatient visits (odds ratio [OR], 2.09) or fewer than three outpatient visits (OR, 1.41) in the 6-30 months before cancer diagnosis were more likely to have an ED visit before their cancer diagnosis.
Other factors associated with increased odds of ED use before cancer diagnosis included rurality (OR, 1.15), residence in northern Ontario (northeast region: OR, 1.14 and northwest region: OR, 1.27 vs Toronto region), and living in the most marginalized areas (material resource deprivation: OR, 1.37 and housing stability: OR, 1.09 vs least marginalized area).
The researchers also found that patients with certain cancers were more likely to have sought care in the ED. They compared these cancers with breast cancer, which is often detected through screening.
“Patients with neurologic cancers had extremely high odds of ED use before cancer diagnosis,” the authors wrote. “This is likely because of the emergent nature of presentation, with acute neurologic symptoms such as weakness, confusion, or seizures, which require urgent assessment.” On the other hand, pancreatic, liver, or thoracic cancer can trigger nonspecific symptoms that may be ignored until they reach a crisis level that prompts an ED visit.
The limitations of the study included its inability to identify cancer-related ED visits and its narrow focus on patients in Ontario, according to the researchers. But the use of the ICES databases also allowed researchers access to a broader pool of data than are available in many other cases.
The findings in the new paper echo those of previous research, the authors noted. Research in the United Kingdom found that 24%-31% of cancer diagnoses involved the ED. In addition, a study of people enrolled in the US Medicare program, which serves patients aged 65 years or older, found that 23% were seen in the ED in the 30 days before diagnosis.

Plasma Omega-6 and Omega-3 Fatty Acids Inversely Associated With Cancer
TOPLINE:
Higher plasma levels of omega-6 and omega-3 fatty acids are associated with a lower incidence of cancer. However, omega-3 fatty acids are linked to an increased risk for prostate cancer, specifically.
METHODOLOGY:
- Researchers looked for associations of plasma omega-3 and omega-6 polyunsaturated fatty acids (PUFAs) with the incidence of cancer overall and 19 site-specific cancers in the large population-based prospective UK Biobank cohort.
- They included 253,138 participants aged 37-73 years who were followed for an average of 12.9 years, with 29,838 diagnosed with cancer.
- Plasma levels of omega-3 and omega-6 fatty acids were measured using nuclear magnetic resonance and expressed as percentages of total fatty acids.
- Participants with cancer diagnoses at baseline, those who withdrew from the study, and those with missing data on plasma PUFAs were excluded.
- The study adjusted for multiple covariates, including age, sex, ethnicity, socioeconomic status, lifestyle behaviors, and family history of diseases.
TAKEAWAY:
- Higher plasma levels of omega-6 and omega-3 fatty acids were associated with a 2% and 1% reduction in overall cancer risk per SD increase, respectively (P = .001 and P = .03).
- Omega-6 fatty acids were inversely associated with 14 site-specific cancers, whereas omega-3 fatty acids were inversely associated with five site-specific cancers.
- Prostate cancer was positively associated with omega-3 fatty acids, with a 3% increased risk per SD increase (P = .049).
- A higher omega-6/omega-3 ratio was associated with an increased risk for overall cancer, and three site-specific cancers showed positive associations with the ratio. “Each standard deviation increase, corresponding to a 13.13 increase in the omega ratio, was associated with a 2% increase in the risk of rectum cancer,” for example, the authors wrote.
IN PRACTICE:
“Overall, our findings provide support for possible small net protective roles of omega-3 and omega-6 PUFAs in the development of new cancer incidence. Our study also suggests that the usage of circulating blood biomarkers captures different aspects of dietary intake, reduces measurement errors, and thus enhances statistical power. The differential effects of omega-6% and omega-3% in age and sex subgroups warrant future investigation,” wrote the authors of the study.
SOURCE:
The study was led by Yuchen Zhang of the University of Georgia in Athens, Georgia. It was published online in the International Journal of Cancer.
LIMITATIONS:
The study’s potential for selective bias persists due to the participant sample skewing heavily toward European ancestry and White ethnicity. The number of events was small for some specific cancer sites, which may have limited the statistical power. The study focused on total omega-3 and omega-6 PUFAs, with only two individual fatty acids measured. Future studies are needed to examine the roles of other individual PUFAs and specific genetic variants.
DISCLOSURES:
This study was supported by grants from the National Institute of General Medical Sciences of the National Institutes of Health. No relevant conflicts of interest were disclosed by the authors.

ATA: Updates on Risk, Diagnosis, and Treatment of Thyroid Cancer
The study, presented by Juan Brito Campana, MBBS, of the Mayo Clinic in Rochester, Minnesota, used Medicare records to perform a secondary analysis of 41,000 adults with type 2 diabetes and moderate cardiovascular risk who were new users of GLP-1 receptor agonists, compared to users of other diabetes medications.
“We took the innovative approach of applying the methodological rigor of a randomized clinical trial to the very large dataset of observational studies,” said Brito Campana.
The results showed a low absolute risk of thyroid cancer, with only 0.17% of patients in the GLP-1 group developing the disease. However, the data also showed a potential relative increase in risk during the first year of GLP-1 receptor agonist use.
“This is likely due to increased detection rather than true incidence, as the latency period for thyroid cancer development is typically longer,” Brito Campana said.
“We also note the limitations of the observational study design, including the short follow-up period and lack of detailed histological data. However, we believe the benefits of GLP-1 receptor agonists likely outweigh the risk of thyroid cancer.”
Malignancy in Bethesda III and IV Thyroid Nodules
At the same ATA session, Sapir Nachum Goldberg, MD, of the University of Pennsylvania, Philadelphia, presented the results of a retrospective record review that examined the prevalence of malignancy in Bethesda III and IV thyroid nodules with negative Thyrogen Receptor Signaling (ThyroSeq) version 3 molecular testing results.
Goldberg reported that 87% of patients with ThyroSeq negative subtype results were managed nonoperatively. “Based on our data, the true prevalence of malignancy likely lies between our low and high estimates of 3% and 23%,” she said. “We believe that the prevalence of malignancy may be higher in real-world practice than validation studies.”
Additionally, nodules with “currently negative” or “negative but limited” ThyroSeq results had a higher prevalence of malignancy (7%), compared with those with a “negative” result (2%). Factors like immediate vs delayed surgery, nodule size, and ultrasound pattern did not significantly impact malignancy prevalence.
The study results also indicated that surveillance ultrasonography is not routinely performed in up to one-third of patients, Goldberg said.
She closed by suggesting that colleagues consider the negative subtype in clinical decision-making. For “negative but limited” nodules, repeat the fine needle aspiration and, for “negative” and “currently negative” nodules, consider ultrasound follow-up as per ATA guidelines for Bethesda II cytology, she said.
RET-Mutated Medullary Thyroid Cancer
For patients with RET-mutated medullary thyroid cancer, Julien Hadoux, MD, PhD, of Institut de Cancérologie Gustave Roussy, Villejuif, France, presented a combined analysis of the efficacy of the RET inhibitor selpercatinib from the phase 1/2 LIBRETTO-001 and phase 3 LIBRETTO-531 trials.
This post hoc analysis used a combined cohort of 509 patients with RET-mutated advanced or metastatic medullary thyroid cancer who had received selpercatinib in the two trials.
Hadoux reported that robust and durable responses were seen across all mutation groups, including M918T, extracellular cysteine, and an “other” group composed of various uncommon RET mutations. “The median [progression-free survival] PFS was not reached for either the M918T or extracellular groups and it was 51.4 months for the Other group,” he said.
“Selpercatinib showed superior median PFS vs control, regardless of the RET mutation. This analysis constitutes the largest catalog of RET mutations in medullary thyroid cancers treated with RET-specific inhibitors.”
TRK-Fusion Differentiated Thyroid Cancer
Steven Waguespack, MD, of the University of Texas MD Anderson Cancer Center, Houston, shared updated efficacy and safety data from three phase 1/2 pooled clinical trials of the tropomyosin kinase receptor (TRK) inhibitor larotrectinib in thyroid cancer. These data updated results initially published in 2022.
“Larotrectinib continues to demonstrate rapid and durable responses, extended survival, and offers a favorable safety profile in patients with TRK fusion differentiated thyroid cancer, with limited activity in anaplastic thyroid cancer,” Waguespack said.
“Additionally, in a subset of patients, we identified some acquired on-target NTRK mutations and off-target GNAS and TP53 mutations that may give further insight into mechanisms of resistance.”
The primary endpoint was the investigator-assessed objective response rate (ORR); at 48 months, the ORR was 79% by independent review. The median PFS in patients with TRK fusion differentiated thyroid cancer was 44 months, while the median duration of response was 41 months. The 4-year overall survival rate was 86%.
Waguespack closed with a cautionary note to colleagues: “While circulating tumor DNA next-generation sequencing (NGS) analysis can be used to test for NTRK gene fusions, negative results should be followed up with tissue-based NGS,” he said.
Brito Campana and Goldberg disclosed no relevant financial relationships. Hadoux reported receiving honoraria for speaker engagements, advisory roles, or funding for CME from Eli Lilly, AAA, IPSEN, Roche, Pharma Mar, and EISAI, and research grants from Novartis, Sanofi, and Eli Lilly.

FROM ATA 2024
Thyroid Cancer Overdiagnosis Continues Despite Cautions
according to a recently published global study.
The proportion of thyroid cancer cases attributable to overdiagnosis globally was higher in women (78%) than in men (68%), with this rate varying substantially across countries, wrote Mengmeng Li, PhD, of the Sun Yat-sen University Cancer Center, Guangzhou, China, and coauthors in an October paper in The Lancet Diabetes & Endocrinology.
Overdiagnosis refers to the diagnosis of lesions that would not cause symptoms and that would not progress, if left alone.
Increased testing for thyroid cancer, fueled in large part by the expansion of imaging technologies and progressively more intense and disorganized scrutiny of the thyroid, led many people to be treated for often indolent lesions, exposing them to potential side effects as well as financial and emotional distress.
Li and coauthors estimate that more than 1.7 million people might have been overdiagnosed between 2013 and 2017 in 63 countries.
“Overdiagnosis clearly emerged in some high-resource countries with private-based health systems in which access to healthcare overrules regulatory controls (eg, in the USA) and in some high-quality public health systems with easy and broad access to thyroid gland diagnostic examinations (eg, in Canada),” Li and coauthors wrote. “Conversely, thyroid cancer is less commonly diagnosed in those countries in which access to diagnosis is guided by strong regulatory rules (eg, in Nordic countries).”
Their study drew from almost 40 years of research, including the latest available data from the World Health Organization’s International Agency for Research on Cancer’s (IARC’s) Global Cancer Observatory. Li and coauthors examined patterns in the time trends of thyroid cancer, mortality data, and trends in diagnosis of thyroid cancer before testing became common in many nations.
This approach is needed in estimating overdiagnosis, where it’s not possible to see what’s happening on a case-by-case level, Salvatore Vaccarella, PhD, a scientist at IARC’s Cancer Surveillance Branch, said in an interview.
Researchers can’t tell whether an individual’s detected early-stage cancers would have remained indolent for years or eventually would have put their life at risk, he said. Instead, the patterns emerge through larger studies of the reported cases of cancer like thyroid tumors and then looking at separate datasets on mortality.
“We can only see that as a big phenomenon when we look at population-based data,” Vaccarella said.
Persisting Problem
Recognition of the harms of overdiagnosis has resulted in some reduction of the incidence of thyroid cancer in the United States, Li and coauthors wrote. After adjusting for age, incidence has fallen from 19 per 100,000 women in 2013 to 16 per 100,000 women in 2017. The proportion of thyroid cancer attributed to overdiagnosis has dropped from 76% to 68% in the country.
The paper adds to the evidence suggesting that the rise in screening has not changed mortality rates for thyroid cancer. For example, Li and coauthors reported seeing “a small decrease in thyroid cancer mortality rates over time in some European countries, but this decline (less than 1 per 100,000 women) is marginal compared with the increases in incidence (reaching around 100 per 100,000 women).”
“Moreover, previous data show that the downward mortality trends had begun before the wide use of ultrasonography for early detection and that period and birth cohort effects have been declining, probably due to treatment advances and reduced prevalence of risk factors, such as the reduction in iodine deficiency,” they wrote.
In an interview, Amanda Davis, MD, of AnMed, a nonprofit health system based in Anderson, South Carolina, said the new paper from Li and Vaccarella provides further evidence for a cautious approach to thyroid nodules given concerns about overdiagnosis.
If early detection of cancer via discovery of thyroid nodules actually helped patients, mortality rates would have dropped with expansion of screening and the resulting diagnoses, said Davis, who is an associate program director at AnMed’s family medicine residency program and affiliate professor at the Medical University of South Carolina, Charleston.
In many cases, people learn they have thyroid lesions after being tested for other conditions such as ultrasound done on carotid arteries to check for stroke risk. The most common form of thyroid cancer is the papillary form. Papillary thyroid cancer tends to be slow growing, carries a low risk for distant metastasis, and in many cases poses little risk. Some small (< 1 cm) papillary thyroid cancers can be monitored with active surveillance as opposed to thyroid lobectomy.
“So just finding more nodules incidentally or through screening ultrasound and even finding more papillary cancers via these methods does not make people healthier or decrease mortality,” Davis said.
“So just finding more things and even finding more papillary cancers does not increase our ability to treat people and keep them alive longer,” Davis said.
The 5-year survival rate for thyroid cancer overall is 98.1% and varies from 99.9% for localized disease to 55.3% for distant disease, the US Preventive Services Task Force (USPSTF) said in a 2017 publication in JAMA. The task force that year gave a “D” rating on screening of asymptomatic people for thyroid cancer. That means there’s moderate certainty that screening for thyroid cancer in asymptomatic persons results in harms that outweigh the benefits. The decision to give this “D” rating meant this screening is not recommended. That’s still the panel’s view.
“You can think of it as a “D” for ‘don’t screen for thyroid cancer,’ ” in people who present no symptoms of this illness, John Wong, MD, the vice chair of the USPSTF, said in an interview.
In primary care, the challenge is assessing thyroid nodules detected when people undergo testing for another reason, such as an ultrasound of the carotid artery to check for stroke risk.
Thyroid nodules can be detected by ultrasonography in up to 68% of the general population, reported a study in American Family Physician. Nodules with suspicious features or ≥ 1 cm require fine needle aspiration. The Bethesda System for Reporting Thyroid Cytopathology can be used to classify samples, with molecular testing applied to guide treatment when fine needle aspiration yields an indeterminate result.
New Thinking on Thyroid Cancer
There’s been a shift in recent years in the approach to how physicians should proceed if certain kinds of thyroid cancer are detected, Cari M. Kitahara, PhD, of the National Cancer Institute noted in a comment accompanying the Li paper.
“Clinicians need to be judicious in the use of thyroid ultrasonography, the diagnostic follow-up of incidentally detected thyroid nodules, and determining the optimal course of treatment,” Kitahara wrote. “For low-risk and incidentally detected tumors, strong consideration should be given to less intensive treatment options (eg, lobectomy, delayed treatment, and active surveillance).”
The American Thyroid Association guidelines encourage de-escalation of treatment for low-risk papillary thyroid carcinoma up to 4 cm.
Physicians often need to make clear to patients how a diagnosis of low-risk papillary thyroid cancer differs from other oncology diagnoses, R. Michael Tuttle, MD, of Memorial Sloan Kettering Cancer Center, New York City, said in an interview.
“I’ll frequently say that everything you’ve ever learned about cancer, you need to forget,” Tuttle said.
Some patients will mistakenly think any cancer diagnosis is a likely death sentence, meaning they should rush to get aggressive treatment. Tuttle has been a leader for many years in efforts in advancing active surveillance as an option for certain people with low-risk thyroid cancer.
“I often start my consultation by saying: ‘We’re going to choose between two right answers here. One right answer is watching right. One right answer is going to surgery,’ ” Tuttle said.
Patients with low-risk thyroid cancer tend to fall into two camps, with maximalists likely to seek quick treatment and minimalists more inclined for surveillance if that’s an option for them, Tuttle said. As opinions have shifted within the medical community about approaches to low-risk thyroid cancer, there’s also been some growing awareness among the public about thyroid overdiagnosis.
“Ten or 15 years ago, people thought we were crazy” to consider active surveillance as an option for low-risk thyroid cancers,” Tuttle said. “Now we have swung, at least in some of the public opinion, to this recognition that every little speck of cancer doesn’t need to be immediately taken out of your body.”
Some patients express regret about having learned that they have low-risk thyroid cancer, Tuttle said.
“Over the last 5 years, it’s not uncommon for patients to ask me, ‘Is this one of those that needs to be treated now, or is this one of those that we wish we would have never found?’ Or people will say, ‘My doctor talked me into an ultrasound, I didn’t want it’ or ‘I had a car wreck, and I found this nodule and I wished I had never found it.’ ”
This study from Li and coauthors was funded by the National Natural Science Foundation of China, the Guangdong Basic and Applied Basic Research Foundation, the Young Talents Program of Sun Yat-sen University Cancer Center, the Italian Association for Cancer Research, and the Italian Ministry of Health.

according to a recently published global study.
The proportion of thyroid cancer cases attributable to overdiagnosis globally was higher in women (78%) than in men (68%), with this rate varying substantially across countries, wrote Mengmeng Li, PhD, of the Sun Yat-sen University Cancer Center, Guangzhou, China, and coauthors in an October paper in The Lancet Diabetes & Endocrinology.
Overdiagnosis refers to the diagnosis of lesions that would not cause symptoms and that would not progress, if left alone.
Increased testing for thyroid cancer, fueled in large part by the expansion of imaging technologies and progressively more intense and disorganized scrutiny of the thyroid, led many people to be treated for often indolent lesions, exposing them to potential side effects as well as financial and emotional distress.
Li and coauthors estimate that more than 1.7 million people might have been overdiagnosed between 2013 and 2017 in 63 countries.
“Overdiagnosis clearly emerged in some high-resource countries with private-based health systems in which access to healthcare overrules regulatory controls (eg, in the USA) and in some high-quality public health systems with easy and broad access to thyroid gland diagnostic examinations (eg, in Canada),” Li and coauthors wrote. “Conversely, thyroid cancer is less commonly diagnosed in those countries in which access to diagnosis is guided by strong regulatory rules (eg, in Nordic countries).”
Their study drew from almost 40 years of research, including the latest available data from the World Health Organization’s International Agency for Research on Cancer’s (IARC’s) Global Cancer Observatory. Li and coauthors examined patterns in the time trends of thyroid cancer, mortality data, and trends in diagnosis of thyroid cancer before testing became common in many nations.
This approach is needed in estimating overdiagnosis, where it’s not possible to see what’s happening on a case-by-case level, Salvatore Vaccarella, PhD, a scientist at IARC’s Cancer Surveillance Branch, said in an interview.
Researchers can’t tell whether an individual’s detected early-stage cancers would have remained indolent for years or eventually would have put their life at risk, he said. Instead, the patterns emerge through larger studies of the reported cases of cancer like thyroid tumors and then looking at separate datasets on mortality.
“We can only see that as a big phenomenon when we look at population-based data,” Vaccarella said.
Persisting Problem
Recognition of the harms of overdiagnosis has resulted in some reduction of the incidence of thyroid cancer in the United States, Li and coauthors wrote. After adjusting for age, incidence has fallen from 19 per 100,000 women in 2013 to 16 per 100,000 women in 2017. The proportion of thyroid cancer attributed to overdiagnosis has dropped from 76% to 68% in the country.
The paper adds to the evidence suggesting that the rise in screening has not changed mortality rates for thyroid cancer. For example, Li and coauthors reported seeing “a small decrease in thyroid cancer mortality rates over time in some European countries, but this decline (less than 1 per 100,000 women) is marginal compared with the increases in incidence (reaching around 100 per 100,000 women).”
“Moreover, previous data show that the downward mortality trends had begun before the wide use of ultrasonography for early detection and that period and birth cohort effects have been declining, probably due to treatment advances and reduced prevalence of risk factors, such as the reduction in iodine deficiency,” they wrote.

FROM THE LANCET DIABETES & ENDOCRINOLOGY
For Radiation ‘Downwinders,’ Cancer Compensation Is On Hold
As of 2022, more than 40,000 patients with cancer successfully applied for $2.6 billion in compensation. Recipients included “downwinders” who were eligible for $50,000 each if they lived in certain areas of Nevada, Utah, and Arizona during specified nuclear testing periods and developed a covered form of cancer.
In June 2024, however, the Radiation Exposure Compensation Program expired amid infighting among Republicans in Congress over whether to expand it. For now, no one can make a claim, even though many downwinders are still alive and continue to be diagnosed with covered cancers decades after they were exposed in the 1940s, 1950s, and 1960s.
There’s a glimmer of good news. The federal government continues to support free medical screenings for eligible people, including certain downwinders and uranium workers. Meanwhile, there are still important roles for clinicians across the country to play as politicians figure out what — if anything — to do next regarding those exposed to radiation.
“We are still here. We can still screen people,” Zachary Davis, program director for the Radiation Exposure Screening and Education Program, The University of New Mexico, in Albuquerque, New Mexico, said in an interview.
Still-Unfolding Legacy of Radiation Exposure
No one knew just how far radiation would spread when the first nuclear bomb was tested in New Mexico in July 1945. Would it cover the state? The entire Southwest? The whole nation?
It also wasn’t clear how radiation would affect people’s health. “There was an awareness that some cancers were caused by radiation, but there wasn’t a cohesive understanding of what the problem was,” Joseph Shonka, PhD, a health physicist who studies radiation exposure and has worked for decades in nuclear engineering, said in an interview.
Now, nearly eight decades later, scientists are still figuring out the full extent of radioactive fallout from nuclear testing. Just last year, a study suggested that radiation from 94 nuclear weapon tests in the Southwest from 1945 to 1962 reached 46 states along with Canada and Mexico.
Activists believe the tests triggered untold number of cancer cases in residents who were exposed in downwind areas:
“My brother died of stomach cancer; my mom died of bone cancer. One of my sisters is surviving brain tumors, and the other one is surviving thyroid cancer,” one New Mexico man recently told ABC-TV’s “Nightline.”
In Idaho, a downwinder advocate told Idaho Capital Sun that everyone who attended a reception for her newly married parents in 1952 — just weeks after a nuclear test — developed cancer or “weird medical complications.” That included her parents, who both had cancer. Her two older brothers, born in 1953 and 1955, also developed cancer, and she’s tracked many other cases in the small town of Emmett.
In Utah, another downwinder advocate told Utah News Dispatch that cancer was common in Salt Lake City neighborhood, where she grew up, which was exposed to fallout. She developed thyroid cancer, her younger sister developed stomach cancer, and an older sister died of lupus, which is connected to radiation exposure. But Salt Lake City isn’t in one of the regions of Utah covered by the federal compensation program, so the advocate can’t get a $50,000 payment.
Downwinders who lived in New Mexico, Idaho, and the Salt Lake City area of Utah are not covered by the federal compensation program. That means none of these people or their descendants are eligible for payments — yet.
Decades After Nuclear Testing, the Government Responds
In 1990, Congress passed the Radiation Exposure Compensation Act, which allowed compensation to people with cancer at several levels. It was later expanded. Downwinders — including those who’ve moved elsewhere over the years — were eligible for $50,000. Onsite participants in nuclear testing could get $75,000. Uranium miners, millers, and ore transporters in 11 states west of the Mississippi River could get $100,000.
Among downwinders, eligible cancers included blood cancers (leukemias with the exception of chronic lymphocytic leukemia, multiple myeloma, and non-Hodgkin’s lymphomas) and a long list of solid organ cancers such as thyroid, breast, stomach, brain, lung, colon, and liver cancers.
“When it comes to blood-related cancers, we do see leukemias, lymphomas, and multiple myeloma, but these cancers were more likely to occur sooner after fallout exposure,” said Laura Shaw, MD, principal investigator who oversees the radiation exposure screening program at the University of Nevada, Las Vegas. “At this point, we see more pancreatic, thyroid, lung, stomach, bladder, and breast cancer.”
The compensation program had major limitations, critics said. “It left out a lot of communities that were exposed,” said Lilly Adams, senior outreach coordinator with the Union of Concerned Scientists (UCS), which supports expanding the program. A national nonprofit organization, UCS was founded more than 50 years ago by scientists and students at the Massachusetts Institute of Technology.
“You have this pretty small amount of one-time compensation, and that’s it,” Adams said in an interview. “You can’t get reimbursed for medical costs or lost wages.” Still, “as flawed as the program is, it’s really valuable for the people who are eligible,” she noted.
Now Congress Is Divided on Next Steps
Some lawmakers have recognized the need to do more for those who developed cancer that’s potentially linked to radiation exposure. As the June 2024 expiration of the Radiation Exposure Compensation Act loomed, Democrats and Republicans in Congress worked together to extend and expand the program.
They introduced a bill for higher compensation — $100,000 per person — and the widening of covered downwinder areas to all of Arizona, Nevada, and Utah (which had only been partially covered), along with all of Colorado, Idaho, New Mexico, Montana, and Guam. Under the legislation, the program also would expand to cover some uranium workers who were on the job after 1971 and residents exposed to nuclear waste in Kentucky, Missouri, and Tennessee.
In March, the new legislation easily passed the US Senate by a vote of 69-30, with support from both political parties — but the Republican-led House hasn’t taken it up. As a result, the Radiation Exposure Compensation Act expired in June, and no one can submit new applications for compensation.
A spokesman for House Speaker Mike Johnson told Missouri Independent “unfortunately, the current Senate bill is estimated to cost $50-$60 billion in new mandatory spending with no offsets and was supported by only 20 of 49 Republicans in the Senate.”
Adams rejected these arguments. “The government spends literally trillions of dollars on our nuclear weapons. Whether or not you support that spending, the human cost of building those weapons should be factored in,” she said. She added that she hopes the House will act by the end of the year to pass the bill, but that’s uncertain.
As Compensation Is On Hold, Medical Screening Continues
A major benefit is still available for downwinders and uranium workers: Free medical screening and referrals for medical treatment. The Radiation Exposure Screening and Education Program’s funding has not been affected by the congressional impasse, so screenings are continuing for eligible people exposed to radiation.
Radiation exposure clinics offer screening in Arizona, Colorado, Nevada, New Mexico, and Utah, and health providers can get funding to offer screening in other affected states.
In Nevada, “we hold screening clinics throughout the state: Caliente, Ely, and Winnemucca. Also, in Reno and Las Vegas, which are not in designated downwind areas, but many downwinders have migrated there,” said Shaw in an interview. Among downwinders, “our youngest patients are in their 60s and range up to a few in their 90s,” she said.
Patients fill out questionnaires that ask about their medical problems, family history, and medications. “Ely patients in particular seem to have extensive family histories of cancer, and this may be due to their location directly downwind of the Nevada Test Site,” Shaw said. (Ely is a remote town in central eastern Nevada near the Utah border.)
The screenings cover both cancer and noncancer conditions. Shaw said clinicians often diagnose problems other than the covered cancers — new cases of atrial fibrillation, diabetes, and hypertension. “We see a ton of prostate and skin cancer” but don’t make patients eligible for the compensation program because they’re not covered, she said.
Even as compensation is on hold, doctors can get the word out that screenings are still available, Shaw said. “We continue to get contacted by individuals who in these communities who have never heard of this program, even though we’ve been holding clinics since 2005,” Shaw said. “Despite outreach activities and advertising through newspapers and radio, we find the most successful method of reaching these patients is through word of mouth — either from other patients or their doctors. That is why we feel it is so important to reach other physicians as well.”
Affected Patients Don’t Just Live in the West
On the outreach front, clinicians in states outside of the western US region can be helpful, too. Shaw urged oncologists nationwide to ask older patients where they lived in the 1950s and 1960s. “Did they live in Nevada, Arizona, Utah, and other Western states that are downwind? They may qualify for needed services and future compensation.”
With regard to compensation, she noted that applicants need to prove that they lived in affected areas many decades ago. And, of course, they must prove that they’ve had cancer. Locating residency records “has often been an enormous challenge.” Old utility bills, pay stubs, and high school annuals can be helpful, “but these records tend to disappear. People and their families throw stuff away.”
Even proving a cancer diagnosis can be a challenge because records can be missing. In Nevada, the law says clinicians only need to keep medical records for 5 years, Shaw said. “Imaging and pathology reports are destroyed. Patients that have been diagnosed with cancer can’t prove it.”
Shaw said she hopes oncologists will offer these messages to patients: “Be an advocate for your own health and keep copies of your own records. Discuss your diagnosis with your family and contact a cancer registry if you are diagnosed with cancer.”

Now, nearly eight decades later, scientists are still figuring out the full extent of radioactive fallout from nuclear testing. Just last year, a study suggested that radiation from 94 nuclear weapon tests in the Southwest from 1945 to 1962 reached 46 states along with Canada and Mexico.
Activists believe the tests triggered untold number of cancer cases in residents who were exposed in downwind areas:
“My brother died of stomach cancer; my mom died of bone cancer. One of my sisters is surviving brain tumors, and the other one is surviving thyroid cancer,” one New Mexico man recently told ABC-TV’s “Nightline.”
In Idaho, a downwinder advocate told Idaho Capital Sun that everyone who attended a reception for her newly married parents in 1952 — just weeks after a nuclear test — developed cancer or “weird medical complications.” That included her parents, who both had cancer. Her two older brothers, born in 1953 and 1955, also developed cancer, and she’s tracked many other cases in the small town of Emmett.
In Utah, another downwinder advocate told Utah News Dispatch that cancer was common in Salt Lake City neighborhood, where she grew up, which was exposed to fallout. She developed thyroid cancer, her younger sister developed stomach cancer, and an older sister died of lupus, which is connected to radiation exposure. But Salt Lake City isn’t in one of the regions of Utah covered by the federal compensation program, so the advocate can’t get a $50,000 payment.
Downwinders who lived in New Mexico, Idaho, and the Salt Lake City area of Utah are not covered by the federal compensation program. That means none of these people or their descendants are eligible for payments — yet.
Decades After Nuclear Testing, the Government Responds
In 1990, Congress passed the Radiation Exposure Compensation Act, which allowed compensation to people with cancer at several levels. It was later expanded. Downwinders — including those who’ve moved elsewhere over the years — were eligible for $50,000. Onsite participants in nuclear testing could get $75,000. Uranium miners, millers, and ore transporters in 11 states west of the Mississippi River could get $100,000.
Among downwinders, eligible cancers included blood cancers (leukemias with the exception of chronic lymphocytic leukemia, multiple myeloma, and non-Hodgkin’s lymphomas) and a long list of solid organ cancers such as thyroid, breast, stomach, brain, lung, colon, and liver cancers.
“When it comes to blood-related cancers, we do see leukemias, lymphomas, and multiple myeloma, but these cancers were more likely to occur sooner after fallout exposure,” said Laura Shaw, MD, principal investigator who oversees the radiation exposure screening program at the University of Nevada, Las Vegas. “At this point, we see more pancreatic, thyroid, lung, stomach, bladder, and breast cancer.”
The compensation program had major limitations, critics said. “It left out a lot of communities that were exposed,” said Lilly Adams, senior outreach coordinator with the Union of Concerned Scientists (UCS), which supports expanding the program. A national nonprofit organization, UCS was founded more than 50 years ago by scientists and students at the Massachusetts Institute of Technology.
“You have this pretty small amount of one-time compensation, and that’s it,” Adams said in an interview. “You can’t get reimbursed for medical costs or lost wages.” Still, “as flawed as the program is, it’s really valuable for the people who are eligible,” she noted.
Now Congress Is Divided on Next Steps
Some lawmakers have recognized the need to do more for those who developed cancer that’s potentially linked to radiation exposure. As the June 2024 expiration of the Radiation Exposure Compensation Act loomed, Democrats and Republicans in Congress worked together to extend and expand the program.
They introduced a bill for higher compensation — $100,000 per person — and the widening of covered downwinder areas to all of Arizona, Nevada, and Utah (which had only been partially covered), along with all of Colorado, Idaho, New Mexico, Montana, and Guam. Under the legislation, the program also would expand to cover some uranium workers who were on the job after 1971 and residents exposed to nuclear waste in Kentucky, Missouri, and Tennessee.
In March, the new legislation easily passed the US Senate by a vote of 69-30, with support from both political parties — but the Republican-led House hasn’t taken it up. As a result, the Radiation Exposure Compensation Act expired in June, and no one can submit new applications for compensation.
A spokesman for House Speaker Mike Johnson told Missouri Independent “unfortunately, the current Senate bill is estimated to cost $50-$60 billion in new mandatory spending with no offsets and was supported by only 20 of 49 Republicans in the Senate.”
Adams rejected these arguments. “The government spends literally trillions of dollars on our nuclear weapons. Whether or not you support that spending, the human cost of building those weapons should be factored in,” she said. She added that she hopes the House will act by the end of the year to pass the bill, but that’s uncertain.
As Compensation Is On Hold, Medical Screening Continues
A major benefit is still available for downwinders and uranium workers: Free medical screening and referrals for medical treatment. The Radiation Exposure Screening and Education Program’s funding has not been affected by the congressional impasse, so screenings are continuing for eligible people exposed to radiation.
Radiation exposure clinics offer screening in Arizona, Colorado, Nevada, New Mexico, and Utah, and health providers can get funding to offer screening in other affected states.
In Nevada, “we hold screening clinics throughout the state: Caliente, Ely, and Winnemucca. Also, in Reno and Las Vegas, which are not in designated downwind areas, but many downwinders have migrated there,” said Shaw in an interview. Among downwinders, “our youngest patients are in their 60s and range up to a few in their 90s,” she said.
Patients fill out questionnaires that ask about their medical problems, family history, and medications. “Ely patients in particular seem to have extensive family histories of cancer, and this may be due to their location directly downwind of the Nevada Test Site,” Shaw said. (Ely is a remote town in central eastern Nevada near the Utah border.)
The screenings cover both cancer and noncancer conditions. Shaw said clinicians often diagnose problems other than the covered cancers — new cases of atrial fibrillation, diabetes, and hypertension. “We see a ton of prostate and skin cancer” but don’t make patients eligible for the compensation program because they’re not covered, she said.
Even as compensation is on hold, doctors can get the word out that screenings are still available, Shaw said. “We continue to get contacted by individuals who in these communities who have never heard of this program, even though we’ve been holding clinics since 2005,” Shaw said. “Despite outreach activities and advertising through newspapers and radio, we find the most successful method of reaching these patients is through word of mouth — either from other patients or their doctors. That is why we feel it is so important to reach other physicians as well.”
Affected Patients Don’t Just Live in the West
On the outreach front, clinicians in states outside of the western US region can be helpful, too. Shaw urged oncologists nationwide to ask older patients where they lived in the 1950s and 1960s. “Did they live in Nevada, Arizona, Utah, and other Western states that are downwind? They may qualify for needed services and future compensation.”
With regard to compensation, she noted that applicants need to prove that they lived in affected areas many decades ago. And, of course, they must prove that they’ve had cancer. Locating residency records “has often been an enormous challenge.” Old utility bills, pay stubs, and high school annuals can be helpful, “but these records tend to disappear. People and their families throw stuff away.”
Even proving a cancer diagnosis can be a challenge because records can be missing. In Nevada, the law says clinicians only need to keep medical records for 5 years, Shaw said. “Imaging and pathology reports are destroyed. Patients that have been diagnosed with cancer can’t prove it.”
Shaw said she hopes oncologists will offer these messages to patients: “Be an advocate for your own health and keep copies of your own records. Discuss your diagnosis with your family and contact a cancer registry if you are diagnosed with cancer.”

As of 2022, more than 40,000 patients with cancer successfully applied for $2.6 billion in compensation. Recipients included “downwinders” who were eligible for $50,000 each if they lived in certain areas of Nevada, Utah, and Arizona during specified nuclear testing periods and developed a covered form of cancer.
In June 2024, however, the Radiation Exposure Compensation Program expired amid infighting among Republicans in Congress over whether to expand it. For now, no one can make a claim, even though many downwinders are still alive and continue to be diagnosed with covered cancers decades after they were exposed in the 1940s, 1950s, and 1960s.
There’s a glimmer of good news. The federal government continues to support free medical screenings for eligible people, including certain downwinders and uranium workers. Meanwhile, there are still important roles for clinicians across the country to play as politicians figure out what — if anything — to do next regarding those exposed to radiation.
“We are still here. We can still screen people,” Zachary Davis, program director for the Radiation Exposure Screening and Education Program, The University of New Mexico, in Albuquerque, New Mexico, said in an interview.
Still-Unfolding Legacy of Radiation Exposure

Cannabis in Cancer: What Oncologists and Patients Should Know
first, and oncologists may be hesitant to broach the topic with their patients.
Updated guidelines from the American Society of Clinical Oncology (ASCO) on the use of cannabis and cannabinoids in adults with cancer stress that it’s an important conversation to have.
According to the ASCO expert panel, access to and use of cannabis alongside cancer care have outpaced the science on evidence-based indications, and overall high-quality data on the effects of cannabis during cancer care are lacking. While several observational studies support cannabis use to help ease chemotherapy-related nausea and vomiting, the literature remains more divided on other potential benefits, such as alleviating cancer pain and sleep problems, and some evidence points to potential downsides of cannabis use.
Oncologists should “absolutely talk to patients” about cannabis, Brooke Worster, MD, medical director for the Master of Science in Medical Cannabis Science & Business program at Thomas Jefferson University, Philadelphia, told Medscape Medical News.
“Patients are interested, and they are going to find access to information. As a medical professional, it’s our job to help guide them through these spaces in a safe, nonjudgmental way.”
But, Worster noted, oncologists don’t have to be experts on cannabis to begin the conversation with patients.
So, “let yourself off the hook,” Worster urged.
Plus, avoiding the conversation won’t stop patients from using cannabis. In a recent study, Worster and her colleagues found that nearly one third of patients at 12 National Cancer Institute-designated cancer centers had used cannabis since their diagnosis — most often for sleep disturbance, pain, stress, and anxiety. Most (60%) felt somewhat or extremely comfortable talking to their healthcare provider about it, but only 21.5% said they had done so. Even fewer — about 10% — had talked to their treating oncologist.
Because patients may not discuss cannabis use, it’s especially important for oncologists to open up a line of communication, said Worster, also the enterprise director of supportive oncology at the Thomas Jefferson University.
Evidence on Cannabis During Cancer Care
A substantial proportion of people with cancer believe cannabis can help manage cancer-related symptoms.
In Worster’s recent survey study, regardless of whether patients had used cannabis, almost 90% of those surveyed reported a perceived benefit. Although 65% also reported perceived risks for cannabis use, including difficulty concentrating, lung damage, and impaired memory, the perceived benefits outweighed the risks.
Despite generally positive perceptions, the overall literature on the benefits of cannabis in patients with cancer paints a less clear picture.
The ASCO guidelines, which were based on 13 systematic reviews and five additional primary studies, reported that cannabis can improve refractory, chemotherapy-induced nausea or vomiting when added to guideline-concordant antiemetic regimens, but that there is no clear evidence of benefit or harm for other supportive care outcomes.
The “certainty of evidence for most outcomes was low or very low,” the ASCO authors wrote.
The ASCO experts explained that, outside the context of a clinical trial, the evidence is not sufficient to recommend cannabis or cannabinoids for managing cancer pain, sleep issues, appetite loss, or anxiety and depression. For these outcomes, some studies indicate a benefit, while others don’t.
Real-world data from a large registry study, for instance, have indicated that medical cannabis is “a safe and effective complementary treatment for pain relief in patients with cancer.” However, a 2020 meta-analysis found that, in studies with a low risk for bias, adding cannabinoids to opioids did not reduce cancer pain in adults with advanced cancer.
There can be downsides to cannabis use, too. In one recent study, some patients reported feeling worse physically and psychologically compared with those who didn’t use cannabis. Another study found that oral cannabis was associated with “bothersome” side effects, including sedation, dizziness, and transient anxiety.
The ASCO guidelines also made it clear that cannabis or cannabinoids should not be used as cancer-directed treatment, outside of a clinical trial.
Talking to Patients About Cannabis
Given the level of evidence and patient interest in cannabis, it is important for oncologists to raise the topic of cannabis use with their patients.
To help inform decision-making and approaches to care, the ASCO guidelines suggest that oncologists can guide care themselves or direct patients to appropriate “unbiased, evidence-based” resources. For those who use cannabis or cannabinoids outside of evidence-based indications or clinician recommendations, it’s important to explore patients’ goals, educate them, and try to minimize harm.
One strategy for broaching the topic, Worster suggested, is to simply ask patients if they have tried or considered trying cannabis to control symptoms like nausea and vomiting, loss of appetite, or cancer pain.
The conversation with patients should then include an overview of the potential benefits and potential risks for cannabis use as well as risk reduction strategies, Worster noted.
But “approach it in an open and nonjudgmental frame of mind,” she said. “Just have a conversation.”
Discussing the formulation and concentration of tetrahydrocannabinol (THC) and cannabidiol (CBD) in products matters as well.
Will the product be inhaled, ingested, or topical? Inhaled cannabis is not ideal but is sometimes what patients have access to, Worster explained. Inhaled formulations tend to have faster onset, which might be preferable for treating chemotherapy-related nausea and vomiting, whereas edible formulations may take a while to start working.
It’s also important to warn patients about taking too much, she said, explaining that inhaling THC at higher doses can increase the risk for cardiovascular effects, anxiety, paranoia, panic, and psychosis.
CBD, on the other hand, is anti-inflammatory, but early data suggest it may blunt immune responses in high doses and should be used cautiously by patients receiving immunotherapy.
Worster noted that as laws change and the science advances, new cannabis products and formulations will emerge, as will artificial intelligence tools for helping to guide patients and clinicians in optimal use of cannabis for cancer care. State websites are a particularly helpful tool for providing state-specific medical education related to cannabis laws and use, as well, she said.
The bottom line, she said, is that talking to patients about the ins and outs of cannabis use “really matters.”
Worster disclosed that she is a medical consultant for EO Care.

One strategy for broaching the topic, Worster suggested, is to simply ask patients if they have tried or considered trying cannabis to control symptoms like nausea and vomiting, loss of appetite, or cancer pain.
The conversation with patients should then include an overview of the potential benefits and potential risks for cannabis use as well as risk reduction strategies, Worster noted.
But “approach it in an open and nonjudgmental frame of mind,” she said. “Just have a conversation.”
Discussing the formulation and concentration of tetrahydrocannabinol (THC) and cannabidiol (CBD) in products matters as well.
Will the product be inhaled, ingested, or topical? Inhaled cannabis is not ideal but is sometimes what patients have access to, Worster explained. Inhaled formulations tend to have faster onset, which might be preferable for treating chemotherapy-related nausea and vomiting, whereas edible formulations may take a while to start working.
It’s also important to warn patients about taking too much, she said, explaining that inhaling THC at higher doses can increase the risk for cardiovascular effects, anxiety, paranoia, panic, and psychosis.
CBD, on the other hand, is anti-inflammatory, but early data suggest it may blunt immune responses in high doses and should be used cautiously by patients receiving immunotherapy.
Worster noted that as laws change and the science advances, new cannabis products and formulations will emerge, as will artificial intelligence tools for helping to guide patients and clinicians in optimal use of cannabis for cancer care. State websites are a particularly helpful tool for providing state-specific medical education related to cannabis laws and use, as well, she said.
The bottom line, she said, is that talking to patients about the ins and outs of cannabis use “really matters.”
Worster disclosed that she is a medical consultant for EO Care.

Risk Assessment Tool Can Help Predict Fractures in Cancer
TOPLINE:
METHODOLOGY:
- Cancer-specific guidelines recommend using FRAX to assess fracture risk, but its applicability in patients with cancer remains unclear.
- This retrospective cohort study included 9877 patients with cancer (mean age, 67.1 years) and 45,875 matched control individuals without cancer (mean age, 66.2 years). All participants had dual-energy x-ray absorptiometry (DXA) scans.
- Researchers collected data on bone mineral density and fractures. The 10-year probabilities of major osteoporotic fractures and hip fractures were calculated using FRAX, and the observed 10-year probabilities of these fractures were compared with FRAX-derived probabilities.
- Compared with individuals without cancer, patients with cancer had a shorter mean follow-up duration (8.5 vs 7.6 years), a slightly higher mean body mass index, and a higher percentage of parental hip fractures (7.0% vs 8.2%); additionally, patients with cancer were more likely to have secondary causes of osteoporosis (10% vs 38.4%) and less likely to receive osteoporosis medication (9.9% vs 4.2%).
TAKEAWAY:
- Compared with individuals without cancer, patients with cancer had a significantly higher incidence rate of major fractures (12.9 vs 14.5 per 1000 person-years) and hip fractures (3.5 vs 4.2 per 1000 person-years).
- FRAX with bone mineral density exhibited excellent calibration for predicting major osteoporotic fractures (slope, 1.03) and hip fractures (0.97) in patients with cancer, regardless of the site of cancer diagnosis. FRAX without bone mineral density, however, underestimated the risk for both major (0.87) and hip fractures (0.72).
- In patients with cancer, FRAX with bone mineral density findings were associated with incident major osteoporotic fractures (hazard ratio [HR] per SD, 1.84) and hip fractures (HR per SD, 3.61).
- When models were adjusted for FRAX with bone mineral density, patients with cancer had an increased risk for both major osteoporotic fractures (HR, 1.17) and hip fractures (HR, 1.30). No difference was found in the risk for fracture between patients with and individuals without cancer when the models were adjusted for FRAX without bone mineral density, even when considering osteoporosis medication use.
IN PRACTICE:
“This retrospective cohort study demonstrates that individuals with cancer are at higher risk of fracture than individuals without cancer and that FRAX, particularly with BMD [bone mineral density], may accurately predict fracture risk in this population. These results, along with the known mortality risk of osteoporotic fractures among cancer survivors, further emphasize the clinical importance of closing the current osteoporosis care gap among cancer survivors,” the authors wrote.
SOURCE:
This study, led by Carrie Ye, MD, MPH, University of Alberta, Edmonton, Alberta, Canada, was published online in JAMA Oncology.
LIMITATIONS:
This study cohort included a selected group of cancer survivors who were referred for DXA scans and may not represent the general cancer population. The cohort consisted predominantly of women, limiting the generalizability to men with cancer. Given the heterogeneity of the population, the findings may not be applicable to all cancer subgroups. Information on cancer stage or the presence of bone metastases at the time of fracture risk assessment was lacking, which could have affected the findings.
DISCLOSURES:
This study was funded by the CancerCare Manitoba Foundation. Three authors reported having ties with various sources, including two who received grants from various organizations.

One-Dose HPV Vaccine Program Would Be Efficient in Canada
In Canada, switching to a one-dose, gender-neutral vaccination program for human papillomavirus (HPV) could use vaccine doses more efficiently and prevent a similar number of cervical cancer cases, compared with a two-dose program, according to a new modeling analysis.
If vaccine protection remains high during the ages of peak sexual activity, all one-dose vaccination options are projected to be “substantially more efficient” than two-dose programs, even in the most pessimistic scenarios, the study authors wrote.
In addition, the scenarios projected the elimination of cervical cancer in Canada between 2032 and 2040. HPV can also lead to oral, throat, and penile cancers, and most are preventable through vaccination.
“The COVID-19 pandemic has impacted HPV vaccination in Canada, particularly among vulnerable population subgroups,” said study author Chantal Sauvageau, MD, a consultant in infectious diseases at the National Institute of Public Health of Quebec and associate professor of social and preventive medicine at the University of Laval, Quebec City, Canada.
Switching to one-dose vaccination would offer potential economic savings and programmatic flexibility, she added. The change also could enable investments aimed at increasing vaccination rates in regions where coverage is suboptimal, as well as in subgroups with a high HPV burden. Such initiatives could mitigate the pandemic’s impact on health programs and reduce inequalities.
The study was published online in CMAJ.
Vaccination Program Changes
Globally, countries have been investigating whether to shift from a two-dose to a one-dose HPV vaccine strategy since the World Health Organization’s Strategic Advisory Group of Experts on Immunization issued a single-dose recommendation in 2022.
In July, Canada’s National Advisory Committee on Immunization (NACI) updated its guidelines to recommend the single-dose approach for ages 9-20 years. The change aligns Canada with 35 other countries, including Australia and the United Kingdom. Canada›s vaccine advisory group still recommends two doses for ages 21-26 years and three doses for patients who are immunocompromised or have HIV.
To help inform new NACI policies, Sauvageau and colleagues modeled several one-dose and two-dose strategies using HPV-ADVISE, an individual-based transmission-dynamic model of HPV infections and diseases. They looked at vaccination programs in Quebec, which has a high HPV vaccine coverage rate of around 85%, and Ontario, which has lower coverage of around 65%.
For one-dose programs, the researchers analyzed noninferior (98% efficacy) and pessimistic (90% efficacy) scenarios and different average vaccine duration periods, including lifelong, 30-year, and 25-year coverage. They compared the scenarios with a two-dose program with 98% efficacy and lifelong duration, estimating the relative reduction in HPV-16 infection and cervical cancer incidence and the number of doses needed to prevent one cervical cancer case.
Overall, the model projected that gender-neutral HPV vaccine programs with either two doses or a noninferior one dose would nearly eliminate HPV-16 infection by 2040-2045 in Quebec and reduce infection by more than 90% in Ontario. Under a one-dose strategy with 90% vaccine efficacy, rebounds in HPV-16 infection would start more than 25-30 years after a switch to a lower-dose strategy, thus providing time for officials to detect any signs of waning efficacy and change policies, if needed, the authors wrote.
In addition, the model projected that a noninferior one-dose, gender-neutral HPV vaccination program would avert a similar number of cervical cancer cases, compared with a two-dose program. The reduction would be about 60% in Quebec and 55% in Ontario, compared with no vaccination. Under the most pessimistic scenario with 25-year vaccine duration, a one-dose program would be slightly less effective in averting cancer: about 3% lower than a two-dose program over 100 years.
All one-dose scenarios were projected to lead to the elimination of cervical cancer in 8-16 years — at fewer than four cervical cancer cases per 100,000 female-years.
One-dose programs would also lead to more efficient use of vaccine doses, with about 800-1000 doses needed to prevent one cervical cancer case in a one-dose program and more than 10,000 incremental doses needed to prevent one additional cervical cancer case in a two-dose program.
What Next?
In Canada, the HPV vaccine is authorized for patients aged 9-45 years. Current immunization coverage among adolescents and young adults varies across provinces and falls below the national target of 90%. In its July 2024 update, NACI estimated that 76% of 14-year-olds of both genders received at least one vaccine dose and that 67% received two doses in 2023. Vaccine uptake was slightly higher among girls than boys.
To boost the coverage rate, shifting to a one-dose schedule could appeal to young people, as well as maintain vaccination efficacy.
“When you look at the studies that have been published worldwide, the effectiveness of one dose of the HPV vaccine is actually quite high,” said Caroline Quach-Thanh, MD, professor of microbiology, infectious diseases, immunology, and pediatrics at the University of Montreal, Quebec, Canada.
Quach-Thanh, who wasn’t involved with this study, previously served as NACI chair and now serves as chair of the Quebec Immunization Committee.
“In terms of prevention of HPV infections that may lead to cancer, whether you give one dose or two doses basically gives you the same amount of protection,” she said.
However, not all physicians agree about the switch in vaccination approaches. In early October, the Federation of Medical Women of Canada released a report with 12 recommendations to increase HPV vaccination rates, including a call for healthcare providers to continue with multidose immunization schedules for now.
“Vaccination is the most powerful action we can take in preventing HPV-related cancers. Canada is falling behind, but we can get back on track if we act quickly,” said Vivien Brown, MD, chair of the group’s HPV Immunization Task Force, chair and cofounder of HPV Prevention Week in Canada, and a past president of the federation.
After the NACI update in July, the task force evaluated the risks and benefits of a single-dose vaccine regimen, she said. They concluded that a multidose schedule should continue at this time because of its proven effectiveness.
“Until more research on the efficacy of a single-dose schedule becomes available, healthcare providers and public health agencies should continue to offer patients a multidose schedule,” said Brown. “This is the only way to ensure individuals are protected against HPV infection and cancer over the long term.”
The study was supported by the Public Health Agency of Canada, the Canadian Institutes of Health Research, the Bill & Melinda Gates Foundation, and Canadian Immunization Research Network. Sauvageau, Quach-Thanh, and Brown declared no relevant financial disclosures.

Time to Stop Saying Thyroid Cancer Is a ‘Good’ Cancer
Papillary thyroid cancer is widely known as the “good cancer.” This term has been around for years and is used ubiquitously. Some think it’s “appropriate” because the cancer is highly treatable and has good survival rates. Yet, recent research, provider experiences, and patient feedback suggest the term should no longer be used.
Papillary is the most common type of thyroid cancer, comprising about 70%-80% of all thyroid cancers. It tends to grow slowly and “has a generally excellent outlook, even if there is spread to the lymph nodes,” according to the American Thyroid Association.
This “excellent outlook” can prompt a physician to call it a “good” cancer.
“There is often a perception that a patient is diagnosed, treated, and then once treatment is complete, gets to go back to their ‘normal’ lives,” said Fiona Schulte, PhD, RPsych, of the University of Calgary, Alberta, Canada.
“The surgery and other treatments thyroid patients may require are not benign and leave patients with many long-term challenging consequences,” she said in an interview. “For many, treatment is just the beginning of a long journey of dealing with multiple late effects.”
Misguided ‘Support’
“I do believe the doctor’s intention is to bring comfort to the patient by saying they have a very curable disease,” Miranda Fidler-Benaoudia, MD, of the University of Calgary, said in an interview. Fidler-Benaoudia is the principal author of a recent survey/interview study of early-onset thyroid cancer survivors, titled “No such thing as a good cancer.” Despite the doctor’s intention, her team found that “for the majority of individuals interviewed, the response was actually quite negative.”
“Specifically,” she said, “thyroid cancer patients felt that the use of the term ‘good cancer’ minimized their diagnosis and experience, often making them feel like their struggles with the diagnosis and its treatment were not justified. While they were indeed cancer patients, they did not feel they could claim to be one because their prognosis was very positive or they didn’t have more intensive therapies like radiotherapy or chemotherapy.”
These feelings were echoed in a recent Moffitt Center article. When Emma Stevens learned she had thyroid cancer at age 19, she said she heard the same statements repeatedly, including: “At least it’s only thyroid cancer.” “It’s the good cancer, and easy to deal with.”
“These are such weird things to say to me,” said Stevens, now 26. “I know they didn’t have any ill will and they couldn’t see how such statements could be upsetting. It’s been my goal to shed some light on how what they see as encouraging thoughts can upset someone like me.”
In an article on the appropriateness of the term “good cancer,” Reese W. Randle, MD, now at Wake Forest University School of Medicine, Winston-Salem, North Carolina, and colleagues wrote, “Patients with papillary thyroid cancer commonly confront the perception that their malignancy is ‘good,’ but the favorable prognosis and treatability of the disease do not comprehensively represent their cancer fight.”
“The ‘good cancer’ perception is at the root of many mixed and confusing emotions,” they continued. “Clinicians emphasize optimistic outcomes, hoping to comfort, but they might inadvertently invalidate the impact thyroid cancer has on patients’ lives.”
Life-Altering
“Having a diagnosis of thyroid cancer, even with usually a very good prognosis, can be life-altering, said Caitlin P. McMullen, MD, a head and neck cancer specialist at Moffitt Cancer Center, Tampa, Florida.
Most papillary thyroid cancers are cured with surgery alone, sometimes followed by radioactive iodine, she said in an interview. “The surgery involves removing half (lobectomy), or sometimes all (total thyroidectomy), of the thyroid gland.” Patients with lymph node involvement have a longer surgery that includes lymph node removal.
Many patients must also remain on medication permanently to replace their thyroid hormone, she continued. And, after treatment is complete, “patients require regular follow up with bloodwork and imaging for many years to ensure the cancer does not return.”
“Repeated visits, medications, and testing can also result in financial toxicities and repeated disruptions for patients,” she added. “These downstream effects of a thyroid cancer diagnosis can significantly alter a patient’s life.”
Kaniksha Desai, MD, Endocrinology Quality Director at Stanford University School of Medicine, Palo Alto, California, said in an interview that thyroid cancer treatments carry some risks that shouldn’t be overlooked and may affect recovery for years. These include:
- Recurrent laryngeal nerve damage: Thyroid surgery can lead to vocal cord paralysis, affecting speech and swallowing.
- Hypoparathyroidism: Postsurgical damage to the parathyroid glands can cause long-term calcium regulation problems resulting in pain and emergency department visits as well as lifelong supplementation with calcium and vitamin D.
- Radioactive iodine (RAI) treatment: RAI can have side effects such as dry mouth, tear duct obstruction, salivary gland dysfunction, and an increased risk of secondary cancers.
- Psychosocial Impact: Being told they have cancer can create significant psychological distress for patients, including fear of recurrence, body image concerns, and anxiety, all of which persist even with a “good prognosis.”
Fidler-Benaoudia’s studies focused specifically on the psychosocial impact on younger patients. “Facing a cancer diagnosis at a young age really forces the person to hit the ‘pause button’ – they may need to take a break from school or work, and it may impact their relationships with their family and friends.”
“Even if their cancer has a very high survival rate, when a young person receives a cancer diagnosis they are often facing their own immortality for the first time, which can be very distressing,” she said. Many of her study participants also struggled to maintain appropriate thyroid hormone levels with medication, which left them feeling tired, losing hair or gaining weight. The surgery itself “can leave a substantial scar on the throat that is visible unless purposefully covered with clothing or accessories,” she noted. “We found that this scar impacted quite a few survivors’ body image.”
Awareness, Education
Two recent studies pointed to the need for clinicians to be aware of their patients’ reactions to a thyroid diagnosis. Susan C. Pitt, MD, associate professor of surgery and director of the endocrine surgery health services research program at the University of Michigan, Ann Arbor, and colleagues reviewed the literature on patient perception of receiving a thyroid diagnosis and found, “Fear and worry about cancer in general and the possibility for recurrence contribute to lasting psychological distress and decreased quality of life. Patients’ perceptions of their diagnosis and resulting emotional reactions influence treatment decision making and have the potential to contribute to decisions that may over-treat a low-risk thyroid cancer.”
In another recent study, Pitt and colleagues assessed fear of thyroid cancer in the general US population and found that close to half of 1136 respondents to an online survey had high levels of thyroid cancer-specific fear, particularly women and those under age 40. “Because disease-specific fear is associated with overtreatment, targeted education about the seriousness, incidence, and risk factors for developing thyroid cancer may decrease public fear and possibly overtreatment related to ‘scared decision-making,’” the authors concluded.
McMullen added, “Taking the time to educate the patient on the diagnosis, prognosis, and treatments can provide reassurance without being dismissive. Most patients are very receptive and understanding once things are explained thoroughly and their questions are answered. We find that factual information can be even more reassuring for patients than saying, ‘This is a good cancer.’”
Desai advised, “Clinicians should acknowledge the spectrum of experiences patients may have.” They should provide empathy and reassurance as well as personalized discussions regarding prognosis and treatment options. In addition, “they should focus on survivorship care by addressing both the long-term and short-term effects on health and lifestyle that can occur post treatment,” as well as the possible need for mental health support.
“I heard many times in residency that, ‘if you had to have cancer, have thyroid cancer,’ ” Malini Gupta, MD, director of G2Endo Endocrinology & Metabolism, Memphis, Tennessee, and vice chair of the American Association of Clinical Endocrinology’s Disease State Networks, said in an interview.
“One should not want any cancer,” she said. “There are some very aggressive tumor markers in differentiated thyroid cancer that can have a worse prognosis. There are many aspects of thyroid cancer treatment that cause anxiety and a stress burden. Recovery varies from person to person.”
“There needs to be education across all sectors of healthcare, particularly in primary care,” she added. “I personally have medullary thyroid cancer that I found myself while fixing my ultrasound. There are many aspects to survivorship.”
Fidler-Benaoudia, Schulte, McMullen, and Desai declared no competing interests. Gupta is on the speaker bureau for Amgen (Tepezza) and IBSA (Tirosint) and is a creative consultant for AbbVie.

Papillary thyroid cancer is widely known as the “good cancer.” This term has been around for years and is used ubiquitously. Some think it’s “appropriate” because the cancer is highly treatable and has good survival rates. Yet, recent research, provider experiences, and patient feedback suggest the term should no longer be used.
Papillary is the most common type of thyroid cancer, comprising about 70%-80% of all thyroid cancers. It tends to grow slowly and “has a generally excellent outlook, even if there is spread to the lymph nodes,” according to the American Thyroid Association.
This “excellent outlook” can prompt a physician to call it a “good” cancer.
“There is often a perception that a patient is diagnosed, treated, and then once treatment is complete, gets to go back to their ‘normal’ lives,” said Fiona Schulte, PhD, RPsych, of the University of Calgary, Alberta, Canada.
“The surgery and other treatments thyroid patients may require are not benign and leave patients with many long-term challenging consequences,” she said in an interview. “For many, treatment is just the beginning of a long journey of dealing with multiple late effects.”
