When was the last time you measured your waistline? If you assume that BMI is the only number to focus on when it comes to your health, think twice. New research has revealed a shocking revelation—your waist circumference might be a far better predictor of men's cancer risk than BMI.

The study finds that for each 4-inch increase in waist size, a man's risk of cancer increases by a staggering 25%. Meanwhile, BMI, commonly regarded as the gold standard for assessing obesity, raises cancer risk by only 19% for the same weight gain. So, if you've been dismissing that pesky belly fat, it's time to take notice.

But why is your waistline so important? The reason is visceral fat—the hidden, deep fat that accumulates around your organs. Unlike other body fat, visceral fat is a stealthy troublemaker, causing inflammation, insulin resistance, and abnormal blood fat levels—all of which combine to create a cancer-perfect storm.

Obesity has been associated with an increased risk of numerous health conditions, including cancer, for decades. The research, though, indicates that a specific measure of the body—waist circumference—may be an even more reliable forecaster of cancer risk in men than the more frequently employed Body Mass Index (BMI). This finding emphasizes the need to pay particular attention to the distribution of fat and not merely to the weight of the body.

BMI has been the go-to measure for years for gauging health risks related to obesity. New research, though, that appears in The Journal of the National Cancer Institute indicates that waist measurement is a better predictor of cancer risk in men. According to the research, four more inches (10 cm) around the waist will add 25% to a man's cancer risk. Conversely, a 3.7 kg/m² rise in BMI (from a BMI of 24 to 27.7) increased cancer risk by only 19%.

Why is waist circumference a better predictor, then? Unlike BMI, which measures weight relative to height, waist circumference actually measures abdominal fat—specifically, visceral fat. This type of fat encircles internal organs and is also linked to higher levels of inflammation, insulin resistance, and abnormal blood lipids, all of which are factors in cancer growth. BMI, however, does not measure fat distribution, so two individuals with the same BMI can have very different levels of health risk depending on where fat is deposited on their bodies.

Why Men Are at Higher Risk?

Interestingly, the research identified a significant difference between men and women when it came to waist circumference and cancer risk. Although waist circumference and BMI were linked with obesity-related cancers in women, the relationship was weaker than for men. An increase of 12 cm (4.7 inches) in waist size or a 4.3 rise in BMI (from 24 to 28.3) raised the cancer risk in women by just 13%—a much lower percentage than for men.

Experts credit this difference to the way that fat is stored in the body. Men are more likely to carry fat around the abdomen, especially as visceral fat, which is more metabolically active and associated with cancer-producing biological alterations. Women, by contrast, store fat in peripheral sites such as the hips and thighs, where it is less likely to drive systemic inflammation and metabolic disturbances.

A possible reason is that men tend to depot fat more in the visceral regions, whereas women tend to carry more subcutaneous and peripheral fat," wrote the researchers. "This may render waist circumference a more robust risk factor for cancer in men and account for why waist circumference provides additional risk information beyond BMI in men but not women."

Cancer Types Most Linked to Abdominal Fat

The research used the International Agency for Research on Cancer (IARC) data to define obesity-related cancers. These cancers are esophageal (adenocarcinoma), gastric (cardia), colorectal, rectal, liver, gallbladder, pancreatic, renal, and thyroid cancers, and multiple myeloma and meningioma. In men, abdominal obesity is especially significant in raising the risk of these cancers through high levels of insulin and markers of inflammation.

For women, the research proposes that both waist circumference and hip circumference may give a more accurate estimate of visceral fat and cancer risk. "Adding hip circumference to risk models could strengthen the link between waist circumference and cancer, especially in women," researchers observed.

What This Means for Men's Health and Cancer Prevention?

With these results, doctors advise men to be more mindful of their waistline than only their BMI. Waist size is an easy method to gauge health risk, and its maintenance through lifestyle changes might be the key to cancer prevention.

How To Reduce Cancer Risk In Men?

Track Your Waist Size: Regularly measure your waist circumference and try to keep it in a healthy range (below 40 inches for men, according to medical advice).

Eat a Balanced Diet: A diet containing high fiber, lean protein, and healthy fats can assist in limiting visceral fat gain.

Exercise Consistently: Regular exercise with a combination of aerobic and strength training will help maintain a healthy waistline.

Control Stress and Sleep: Persistent stress and inadequate sleep tend to cause weight gain, especially in the midsection of the body.

Regular Health Screenings: Early identification of cancer risk factors through regular screening can greatly enhance long-term health status.

The number of autistic women is same as the number of autistic men, but women know to hide it well, says research. A study published in the BMJ, found that while the rates of diagnosis for autistic is found among young boys and girls, rates are almost identical by the time they reach adulthood. However, these new findings have also shown that women are more likely to "mask" signs of autism in order to fit in. This is why their diagnosis is done far later.

What Did The Study Find Out?

This is the first major study to find such high levels of condition among women. Previously, diagnoses rates were four times higher among boys and men than females.

Specialists say the findings highlight the urgent need to move away from outdated stereotypes that still influence how autism is recognized and diagnosed.

The international study, led by researchers at the Karolinska Institutet in Sweden, examined autism diagnosis rates among people born in Sweden between 1985 and 2000. More than 2.7 million individuals were followed for up to 37 years, making it one of the most comprehensive studies of its kind.

By 2022, around 2.8 per cent of the population studied had been diagnosed with autism spectrum disorder. The data revealed a clear pattern. In early childhood, boys were far more likely than girls to receive an autism diagnosis. However, this gap steadily narrowed during adolescence.

By the time participants reached their late teens and early 20s, diagnosis rates among men and women were broadly similar. Researchers noted that the male to female ratio of autism diagnoses decreased over time to the point that it may no longer be distinguishable in adulthood.

A Catch-Up Effect in Adolescence

Dr Caroline Fyfe, lead author of the study from the University of Edinburgh, said autism has long been viewed as a condition that mainly affects males. While that pattern was still visible in children under 10, the picture changed rapidly during adolescence.

She explained that diagnoses among girls rose sharply in the teenage years, creating what researchers described as a female catch-up effect. By the age of 20, autism rates were almost equal between men and women. According to Dr Fyfe, this suggests late or missed diagnoses in females rather than a true biological difference between sexes.

Masking and Mental Health Misdiagnoses

Experts say one major reason for delayed diagnosis is masking. Girls and women are often more likely to imitate social behavior, maintain eye contact and suppress traits traditionally associated with autism. While this can help them fit in socially, it can also make their difficulties harder to identify in clinical settings.

Dr Judith Brown from the National Autistic Society said gender should never be a barrier to diagnosis or support. She noted that autistic women who are misdiagnosed often develop additional mental health challenges due to years without appropriate understanding or help.

She added that the exhaustion of constant masking can contribute to anxiety and depression, reinforcing the importance of recognizing autism earlier in girls.

Clinical Biases Under Scrutiny

Dr Steven Kapp, senior lecturer in psychology at the University of Portsmouth, said research has consistently shown that clinical biases play a role in under-recognizing autism in women and girls. He explained that subtler behaviors and social adaptation often lead clinicians to overlook autism in females.

A linked editorial written by a patient and advocate echoed these concerns, warning that autistic women are frequently labelled with mood or personality disorders while waiting for a correct diagnosis. As a result, many are forced to self-advocate simply to be recognized as autistic.

Experts say the findings should prompt changes in diagnostic approaches, ensuring that autistic girls and women are no longer left unseen.

Actor Claire Foy has revealed that a long, uncomfortable health struggle picked up while travelling ended up reshaping her relationship with caffeine. The Crown star, 41, said she gave up tea and coffee after discovering she had stomach parasites, an experience she described as “gross” and “absolutely rank.”

Foy shared the story during her appearance on The Table Manners Podcast with hosts Jessie and Lennie Ware on February 4, where the conversation moved from food to a period of unexplained weight loss and constant hunger.

“I kept losing weight, and I didn’t know what was going on,” she told the hosts. Despite eating regularly, she said she never felt full. “I was so hungry,” Foy recalled, adding that the situation left her confused and worried.

Diagnosis After Years of Symptoms

The actor explained that the cause was eventually traced back to stomach parasites she had picked up while travelling in Morocco. The diagnosis came after medical tests, including stool samples, which she candidly described as unpleasant but necessary.

According to Foy, doctors told her she had been carrying the parasites for around five years, a length of time she herself described as “quite a long time.” While she did not name the specific parasites, she shared one detail that stuck with her. “They travel as a pair, I got told by the doctor,” she said, reacting with visible disgust even years later.

Living with the condition took a toll on her body and routine. The ongoing symptoms pushed her to rethink how she approached treatment and daily habits, including what she consumed.

Clair Foy Had Parasites For 5 Years: Why Caffeine Had to Go

It was during treatment that Foy made the decision to give up caffeine entirely. She explained that she wanted to avoid very strong antibiotics if possible and instead followed a strict diet alongside other treatments. “I basically had to go on this diet,” she said. “I didn’t want to take really hardcore antibiotics.”

As part of that process, caffeine was cut out. “I took all this gross stuff and part of that was giving up caffeine,” Foy told the hosts. At the time, it was a major shift. She admitted she had been a heavy caffeine consumer, drinking around 15 cups of tea a day along with two coffees she had carefully planned into her schedule.

A Habit That Never Came Back

Giving up caffeine was not easy, but once she did, Foy decided to stick with it. “Once you’ve given it up, it’s such a mission to give it up, that I was like, well, maybe I’ll just give it a go,” she said.

Now fully caffeine-free, she even brought her own tea bags to the podcast recording. The show is known for hosts and guests sharing food and drinks in the Ware family kitchen, making her preparation a small but telling detail of how seriously she takes the change.

Medical experts note that parasitic infections usually require medication to clear completely, often involving antiparasitic drugs and sometimes antibiotics or antifungals. In many cases, a combination of treatments is needed.

"I went into chemo-induced menopause at 37," said Lisa Ray, a Canadian actress during an interview with BBC. She also shared the clip of the interview on her Instagram account talking about the importance of awareness about the side effects of cancer and its treatment on women. Sharing the clip on her Instagram story, she wrote "This is me in menopause. Menopause does not have one face...I went into premature chemo-induced menopause at 37."

She revealed that she had blood cancer, called Multiple Myeloma. "At that time, it was the least of my worries. I had a blood cancer called Multiple Myeloma to contend with… But after recovering, I could focus on what being in menopause suddenly at 37 would mean. And I had no one to talk to," said Lisa, now 53.

What Is Chemo-induced Menopause?

Chemotherapy do not just target cancer cells, but it can also harm healthy cells, which are fast diving. Ovaries fall into that category and thus they stop producing hormones like estrogen and progesterone, which pushes the body into sudden menopause.

This condition is called iatrogenic menopause or chemotherapy-induced ovarian failure. While it could be temporary for some people, for others, it could be permanent. Experts explain that women under 30 could see their periods return after the treatment.

Chemotherapy works by attacking cells that grow and divide rapidly. While this helps destroy cancer cells, it also affects healthy cells, such as those responsible for hair growth, which is why hair loss is a common side effect.

This process can also impact reproductive organs, including the ovaries, and disrupt hormone production. As a result, levels of estrogen and progesterone—the key hormones involved in menopause—may become imbalanced due to chemotherapy’s effects on the endocrine system.

Damage to cells and these hormonal shifts can trigger menopausal symptoms and, in some cases, cause periods to stop altogether.

For people over 40, hormone levels may already be naturally declining. In such cases, chemotherapy can accelerate a menopausal transition that has already begun.

Chemo-induced Menopause Symptoms

The symptoms are same as one experiences in natural menopause, which include:

• Hot flashes
• Night sweats
• Mood swings
• Fatigue
• Vaginal dryness
• Loss of libido

However, Lisa also points out the emotional impact, which could be intense especially for someone who is young and was not expecting to face menopause for decades. “Both menopause and disease-induced menopause have been treated with shame and silence for too long,” Lisa wrote on her Instagram post.

Chemo-induced Menopause: What Can Help?

Hormone Replacement Therapy (HRT): When considered safe and not restricted by hormone-sensitive cancers, HRT can help manage symptoms while supporting bone strength and heart health.

Non-hormonal treatments: Certain medications, including SSRIs, SNRIs, and gabapentin, may reduce hot flashes, while vaginal moisturizers and lubricants can relieve dryness.

Lifestyle changes: Staying physically active, following a calcium and vitamin D-rich diet, maintaining a healthy weight, and managing stress can significantly support overall wellbeing.

Fertility support: Options such as egg or embryo freezing before treatment, along with consultations with a fertility specialist afterward, may help preserve future parenthood possibilities.
