Not all cancers should be treated right away, medical experts say — here’s why
NEWYou can now listen to Fox News articles!
When someone gets a cancer diagnosis, the initial reaction is usually to undergo treatment as quickly as possible — but for some types of disease, doctors may recommend a more conservative approach.
For certain cancers, immediate or aggressive treatment can cause more harm than good, according to multiple medical experts.
For example, treating slow-growing tumors with surgery, radiation or chemotherapy could create significant side effects without a survival benefit.

“The fact that so many cancers will never kill you is not a justification for not knowing, because there is still plenty of room for ‘watchful waiting,’ as well as interventions that may improve quality of life even if they don’t extend life,” Dr. Marc Siegel, Fox News senior medical analyst, told Fox News Digital.
This is especially true as targeted cancer treatments emerge, which are more personalized and less likely to cause severe side effects, according to the doctor.

“The fact that cancers are occurring earlier is a justification for heightened screenings, not the opposite,” Siegel added. “Information is power — what you do with that information is based on clinical judgment and the art of medicine.”
Below are some types of cancer that may not warrant treatment, according to research and doctors’ guidance.
No. 1: Prostate cancer (low-risk)
While some types of prostate cancer should be treated right away, others are better addressed by “watchful waiting,” according to Sanoj Punnen, M.D., a urologic oncologist with Sylvester Comprehensive Cancer Center, part of the University of Miami Health System.
“With respect to prostate cancer, for most low-risk cancers (Gleason 6 or grade group 1), we recommend initial observation and surveillance rather than immediate treatment,” he told Fox News Digital.

The Gleason score is a grading system that ranks prostate cancer cells in terms of how abnormal they are, with 6 being the lowest grade and 10 being the highest grade (barely resembling normal cells).
“For high-grade tumors like Gleason 8, 9 or 10, we believe they progress quickly, so we recommend treatment to prevent the risk of metastasis,” said Punnen, who is also vice chair of research and a professor with the Desai Sethi Urology Institute at UHealth. “For low-risk tumors, we think they pose little risk, so we recommend just observation.”
“The fact that cancers are occurring earlier is a justification for heightened screenings, not the opposite.”
“But in the end, we can’t be sure, so our approach to observation includes serial monitoring of cancer status with PSA, MRI and occasional biopsy to ensure the tumor isn’t progressing.”
No. 2: Ductal carcinoma in situ (DCIS)
Also known as stage 0 breast cancer, DCIS is a non-invasive disease marked by abnormal cells in the lining of the breast milk ducts. The “in situ” is Latin for “in the original place,” which indicates that the cancer has not spread outside the milk ducts.
For this precancerous, very early-stage breast condition, careful monitoring may be more prudent than immediate surgery, research shows.

A 2024 study by the Dana-Farber Cancer Institute found that active monitoring for DCIS resulted in similar quality of life, mental health and symptom progression over a two-year period compared to a standard surgical approach.
NEW STUDY QUESTIONS WHETHER ANNUAL MAMMOGRAMS ARE NECESSARY FOR MOST WOMEN
“These results suggest that in the short term, active monitoring is a reasonable approach to management of low-risk DCIS,” the lead researcher said in a press release. “If longer-term follow-up supports the safety of active management from a cancer outcome standpoint, this approach could be considered as an option for women with this condition.”
“But it is also critical that we understand how women feel when they are living with this ‘watch and wait’ approach and how it impacts their overall quality of life.”
Other research has suggested that women with low-risk DCIS did not have a higher rate of invasive cancer after two years of active monitoring, although each patient should discuss their individual risk level with an oncologist.
No. 3: Indolent (slow-growing) lymphomas
Non-Hodgkin lymphoma (NHL) is a type of cancer that starts in the lymphatic system, which includes the lymph nodes, spleen, thymus, bone marrow and other tissues.
Indolent lymphomas are those that “grow and spread slowly,” according to the American Cancer Society.
THE DEADLY CANCER HIDING IN PLAIN SIGHT — AND WHY MOST PATIENTS NEVER GET SCREENED
The National Comprehensive Cancer Network (NCCN) recommends watchful waiting for asymptomatic, slow-growing follicular lymphoma, as a means of avoiding the toxicity of chemotherapy and immunotherapy until it’s absolutely necessary.
The Lymphoma Research Foundation confirms that doctors recommend “active surveillance” for some patients with slow-growing lymphoma.

“This approach may be started after the initial diagnosis or after relapse, depending on the situation,” the foundation states on its website. “Active treatment is started if the patient begins to develop lymphoma-related symptoms or if there are signs that the disease is progressing.”
Treatment should be started right away for aggressive (fast-growing) lymphomas.
No. 4: Chronic lymphocytic leukemia
One of the most common adult leukemias, chronic lymphocytic leukemia (CLL) originates in white blood cells (lymphocytes) in the bone marrow and then spreads to the bloodstream, according to the American Cancer Society.
CLL tends to grow slowly, with many patients experiencing no symptoms for years. Eventually, the cancer calls can spread to the lymph nodes, liver and spleen.
BREAKTHROUGH BLOOD TEST COULD SPOT DOZENS OF CANCERS BEFORE SYMPTOMS APPEAR
Some studies have shown that early treatment for CLL does not improve survival rates compared to observation, and that the benefits may not outweigh the risks.
In a 2023 study presented at the European Hematology Association 2023 Congress in Frankfurt, Germany, researchers found that early treatment did not prolong overall survival compared to a placebo in patients with early, asymptomatic CLL.

“I believe it’s fair to conclude that ‘watch-and-wait’ should remain the standard of care in the era of targeted drugs,” said researcher Petra Langerbeins, M.D., when presenting the findings.
No. 5: Low-grade endometrial cancer
For most patients with endometrial cancer, surgery is the first treatment, which entails removing the uterus, fallopian tubes and ovaries, according to the American Cancer Society.
However, in certain patients with low-grade cancer, such as older people, those with “frailty” and people with major health issues, doctors may recommend deferring surgery, which can pose a high risk.

In cases where the patient has medical comorbidities or wants to preserve fertility, hormone treatment may be used instead of surgery, per the ACS.
“It’s usually also considered for cancer that is lower-grade, low-volume and slow-growing,” the above source stated.
No. 6: Some early kidney cancers
In cases of kidney cancer with small tumors (≤3 cm) or benign lesions, doctors may recommend monitoring them instead of undergoing surgery for removal.

The American Urological Association confirms that active surveillance is an option for some small renal masses (localized tumors).
“I believe it’s fair to conclude that ‘watch-and-wait’ should remain the standard of care in the era of targeted drugs.”
Deferred treatment is particularly recommended for older patients or those with “significant comorbidities,” research shows.
“Shared decision-making about active surveillance should consider risks of intervention/competing mortality versus potential oncologic benefits of intervention,” the UAU states in its guidance.

Data from the Delayed Intervention and Surveillance for Small Renal Masses (DISSRM) Registry showed that patients with active surveillance had a 99% or greater cancer-specific survival rate — virtually the same as patients who received immediate treatment.
No. 7: Small papillary thyroid cancers
Papillary thyroid cancer (PTC), the most common type of thyroid cancer, may not warrant treatment for small tumors measuring 1 centimeter (10 mm) or less, which are called microcarcinomas.

Research found that when using active surveillance for 10 to 20 years, less than 10% experienced significant growth, only 5% developed lymph node spread and there were no thyroid-cancer deaths.
The American Thyroid Association’s guidelines officially recommend active surveillance for very low-risk microcarcinomas.

Research continues to uncover new details on how fasting may help extend life.
A new study published in the journal Nature Communications investigated how intermittent fasting can boost longevity in small worms often used in aging research.
Researchers from the University of Texas Southwestern Medical Center in Dallas compared worms that were fed normally to those that underwent a 24-hour fast in early adulthood and were then fed again, according to a press release.
POPULAR INTERMITTENT FASTING DIETS MAY NOT DELIVER THE HEALTH BENEFITS MANY EXPECT
The scientists measured a variety of factors, including stored fat, gene activity related to fat metabolism and lifespan.
The results showed that the life-boosting benefit did not depend on the fasting itself but on the body’s behavior after eating again.

Study lead Peter Douglas, associate professor of molecular biology and a member of the Hamon Center for Regenerative Science and Medicine at UT Southwestern, suggested that these discoveries “shift the focus toward a neglected side of the metabolic coin – the re-feeding phase.”
“Our data suggest that the health-promoting effects of intermittent fasting are not merely a product of the fast itself, but are dependent on how the metabolic machinery recalibrates during the subsequent transition back to a fed state,” he said.
PEOPLE LOST WEIGHT WHILE EATING SIGNIFICANTLY MORE FOOD — HERE’S THE SECRET
“Our findings bridge a gap between lipid metabolism and aging research,” he added. “By targeting aging, the single greatest risk factor for human disease, we move beyond treating isolated conditions toward a preventive model of medicine that enhances quality of life for all individuals.”
Lauri Wright, director of nutrition programs at the University of South Florida’s College of Public Health, called this a “high-quality” study that adds an “important nuance to how we think about fasting and longevity.”
Intermittent fasting typically involves limiting meals to an eight-hour daily window or fasting every other day. (iStock)
The benefits of the refeeding phase after fasting were “especially interesting,” Wright, who was not involved in the study, told Fox News Digital.
“The researchers showed that longevity was linked to the body’s ability to turn off fat breakdown after fasting, allowing cells to restore energy balance,” she reiterated.

“From a scientific standpoint, that’s a meaningful shift because it suggests fasting is not just about burning fat, but about metabolic flexibility.”

Fasting may support longevity through triggering metabolic switching, enhancing cellular repair and stress resistance and improving markers like insulin sensitivity, research shows.
Limitations and cautions
Although this study provides “important insight” on the power of refeeding, Wright noted that the findings should be approached with caution, as the study was done on worms and cannot always be translated to humans.
“Additionally, it explains how a process might work in a controlled lab condition rather than real-world eating behaviors,” she added as a limitation. “Finally, the study is short-term and doesn’t give us the long-term translation on lifespan outcomes.”
The review found intermittent fasting was barely more effective than doing nothing, according to the study authors. (iStock)
Wright cautioned that fasting is “not a magic solution for longevity, and how you eat overall matters more than when you eat.”
“I advise, first and foremost, to focus on diet quality, including a variety of fruits and vegetables, healthy fats and minimally processed foods,” she said.

For those who are considering fasting, it’s better to stick with a moderate plan — like a 12- to 14-hour overnight fast — rather than going to extremes, Wright said. After fasting, she recommends focusing on well-balanced meals.

Several groups of people should be cautioned against fasting, according to Wright, including those with diabetes who are on insulin or hypoglycemic medications, those who are pregnant or breastfeeding, anyone with a history of eating disorders and older adults at risk of malnutrition.
Anyone considering intermittent fasting should consult with a doctor before starting.

More than three million people travel to undergo cosmetic surgery each year, statistics show — but the potential savings come at a cost.
Most people opting to pursue this so-called “medical tourism” are chasing budget-friendly price tags.
International surgeries, such as hair transplants in Turkey, can cost as little as $4,000 to $5,000 compared to $20,000 to $30,000 in the U.S., but often come with extreme risks, according to board-certified plastic surgeon Dr. Sheila Nazarian of California.
DOCTORS WARN OF ‘LOOKSMAXXING’ DANGERS AFTER INFLUENCER’S LIVESTREAM EMERGENCY
The doctor recently joined Lisa Brady on the “The FOX News Rundown” podcast to discuss the rising trend of medical tourism. One of the biggest risks, she said, is the lack of safety regulations in popular destinations like Mexico and Turkey.
As demand spikes in these medical tourism “mills,” there have been reports of non-medically trained staff performing procedures like hair transplants.

“I’ve heard that they [international clinics] are even recruiting people who maybe were taxi drivers and then putting them through their own training program … to become hair transplant technicians,” Nazarian said. “That’s how high the demand has become.”
In the U.S., medical school graduates are granted a “physician and surgeon” license, which means doctors — including pediatricians or OB-GYNs — can legally perform cosmetic surgeries, even if they didn’t receive specialized training for those procedures during residency, Nazarian noted.
WHAT IS BUTT MICRONEEDLING? BEHIND THE ‘DESPERATE’ PROCEDURE KELLY RIPA TRIED
Instead of pinching pennies, the doctor recommended paying whatever amount is necessary to ensure quality treatment.
“People think of it as, you know, going to the mall. … It’s surgery, and surgery has risks,” she said. “You need to be with someone who not only can perform a beautiful surgery, but who can handle possible complications well.”
“You need to ask them: ‘What was your residency training in? And if you wanted to, would you be allowed to do this procedure in a hospital?’”
Aftercare is another critical factor in the success and safety of a cosmetic procedure, as the doctor emphasized that 20% of a surgical result depends on post-operative care.

This can be difficult or even impossible to manage when a doctor is in a different time zone, she cautioned, or if the clinic disappears shortly after the procedure.
Nazarian also noted the importance of addressing the psychological component of plastic surgery, noting that no procedure will fix underlying unhappiness. The doctor said she uses screening questionnaires to ensure that patients are truly seeking self-improvement rather than a “cure” for deeper issues.

“If you’re not already generally very content with your life, a knife in my hand is not going to bring you there,” Nazarian said.
“The analogy I always give is you don’t want a paisley couch — you want a neutral couch and you can put paisley pillows on it,” she said, noting that a procedure should “make you look normal, God-given, athletic. And then you can change your clothes when the trends come and go.”

Samuel Golpanian, M.D., a double board-certified plastic surgeon in Beverly Hills, said he has also seen an increasing number of patients undergoing cosmetic procedures abroad, sometimes with “devastating consequences.”
“The key is being extremely careful before embarking on this journey.”
“I’ve seen a wide range of complications, including infections, poor wound healing, significant scarring and tissue necrosis (skin death),” he told Fox News Digital. “These complications often lead to prolonged pain, ongoing medical problems, and significant additional costs to repair the damage.”

Golpanian said he’s treated patients who received unsafe or non-medical-grade injectable materials, which can lead to serious long-term health issues.

“That said, I’ve also seen some good outcomes, so it’s not all bad,” he noted. “The key is being extremely careful before embarking on this journey.”
Quick tips for safe ‘medical tourism’
Fully vet the surgeon. “Most surgeons will provide information about their education and training, but it’s important not to accept these claims at face value,” Golpanian said. “Verify them directly by contacting the institutions where they trained.”
Ask for references from prior patients. Ideally, it’s best to get references from U.S.-based patients who can speak candidly about both their experience and their results, the surgeonsaid.
Think beyond the cost. Golpanian emphasized the adage “you get what you pay for.” “Cost should take a back seat to experience, training, judgment and proven results,” he advised.
Be cautious about relying on before-and-after photos. These can be selective or even enhanced, Golpanian warned.
Keep aftercare in focus. “Make sure the practice emphasizes comprehensive follow-up care and has a clear, realistic post-operative plan in place.”
