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.

Feeling anxious, unable to perform well, and feeling burnt out at the workplace is a common problem facing employees slogging for over nine hours every day. But now, a study suggests that taking short vacations every two months can help reduce stress accumulation.

In a 2025 research paper titled “Maximizing Recovery: The Superiority of Frequent Vacations”, Selvaraj Giridharan from the Oncology Department at Tawam Hospital in Abu Dhabi suggests that taking short breaks can help improve mental well-being and boost work performance.

The study argued that instead of a long annual vacation, frequent short breaks are often more effective and help people mentally detach from work. This also helps them recover from burnout faster.

Researchers also found that the positive effects of vacations usually fade within a few weeks after returning to work, making regular breaks important for maintaining emotional balance and productivity.

"We emphasize how regular vacations facilitate recovery and enhance well-being, thereby reducing stress and improving performance. We advocate the integration of frequent breaks into workplace culture through practical strategies for both individuals and organizations," wrote study author Selvaraj Giridharan.

Amid discussions around 70-hour work weeks advocated by industrialists like Narayana Murthy, the study comes as a breather.

The researchers, including experts from the National Health Service, stressed that sustained work-related stress causes significant psychobiological strain. This depletes physiological and psychological resources, manifesting as elevated cortisol levels, cognitive fatigue, and emotional exhaustion.

Without periodic recovery, this strain accumulates, increasing the risk of burnout, reduced productivity, and adverse health outcomes. India has seen several recent cases where workplace stress has affected people’s mental health, with some collapsing at work while others resorted to suicide.

Vacations Linked To Better Mood, Sleep, And Heart Health

The paper cited a meta-analysis of 22 studies that showed that vacations provide substantial psychological, physiological, and cognitive benefits.

It noted post-vacation reductions in exhaustion, improvements in mood, and increases in life satisfaction among employees.

The findings were found consistent with several studies which identified physiological improvements, including reduced cortisol levels, enhanced heart rate variability, and better sleep quality. These outcomes reflect mitigation of the physiological burden of chronic stress and position vacations as vital health interventions.

The researcher stated that vacations are essential for mitigating the psychobiological impacts of contemporary work and providing psychological, physiological, and cognitive advantages.

Although the duration of vacations is significant, frequent and shorter vacations are more effective in maintaining well-being through regular recovery, they said.

"This evidence-based perspective, rooted in effort-recovery theory, advocates strategic vacation planning by organisations and policymakers to prioritise workforce health. Societies should promote vacation policies that emphasise frequency in order to enhance employee well-being and performance,” the paper said.

In India, poor reproductive health awareness remains one of the most overlooked gaps in women’s healthcare. Many women continue to ignore gynecological symptoms, assuming them to be routine, temporary, or too embarrassing to discuss.

Persistent vaginal infections, irregular bleeding, untreated hormonal disorders, chronic pelvic pain, or recurring inflammation are often dismissed until they become severe. In some cases, these untreated or undiagnosed conditions can silently contribute to long-term health risks, including certain cancers.

The Problem With Partial Awareness

Today, many women have heard of conditions like PCOS, endometriosis, or fibroids. But awareness is often incomplete. Women may know the name of a condition, yet not know its warning signs, complications, or when medical attention is necessary.

For example, prolonged hormonal imbalance, obesity, irregular periods, and chronic inflammation may increase the risk of certain gynecological cancers over time. Similarly, lack of awareness about HPV, cervical screening, and vaccination continues to delay prevention and early diagnosis of cervical cancer.

Fertility awareness is another important gap. Many women are not familiar with their menstrual cycle, ovulation pattern, or normal reproductive changes. When women do not know what is normal for their own body, it becomes harder to recognize when something is wrong.

Social media has added another layer to this problem. While it has improved access to health information, it has also created confusion. Quick tips, unverified remedies, and incomplete advice can delay proper diagnosis and treatment.

The Knowledge Gap That Matters

Reproductive literacy is not just about knowing symptoms. It means understanding one’s body, menstrual cycle, sexual health, fertility, contraception, screening options, vaccination, and access to safe healthcare.

Unfortunately, stigma around sexual and reproductive health still prevents many women from seeking timely care. Symptoms such as abnormal discharge, bleeding after intercourse, pelvic pain, or irregular bleeding are often hidden out of fear, shame, or hesitation.

This delay is especially dangerous in cancers such as cervical, uterine, ovarian, and vaginal cancers, where early evaluation can make a major difference.

Actress Lisa Ray was diagnosed with Multiple Myeloma, an incurable but treatable blood cancer, in 2009. She successfully went into remission but experienced a cancer relapse shortly after her wedding in 2012.

During her journey to recovery, she became a prominent advocate for cancer awareness and research. However, it was during this period, at the age of 37, that she also suffered chemo-induced menopause — a topic she brushed aside, not wanting to bring it up out of shame and fear, reflecting the taboo society still associates with the natural end of a woman’s reproductive phase.

In an interaction with HealthandMe, the Oscar-nominated film Water (2005) actress opened up about her experience with chemo-induced menopause.

“I went into chemo-induced menopause at 37. I was given no support. I was completely lost. And even for a subsequent decade after that, I couldn’t find any answers. I didn’t know how to take care of myself. I didn’t know I had options,” she said.

‘I Carried This Burning Secret Inside Me’

The actress shared that she normalized many of her symptoms and avoided speaking openly about menopause despite being candid about cancer.

“I was so vocal about cancer. I’m actually somebody who prefers to be quite truthful about what I’m going through. I don’t really like to hide things. I’m not secretive by nature. And yet, I carried this burning secret inside me for so many years,” she said.

“When I was being lauded as someone who was breaking through the silence of cancer, I was carrying the silent secret inside me. I couldn’t understand why for many years. And I realized today, I was carrying shame.”

She noted that menopause continues to remain a deeply misunderstood and under-discussed subject, despite affecting all women.

‘Menopause Was Like A Black Box’

Lisa said conversations around menopause were absent even within families.

“My mother never talked to me about menopause. Of course, we discussed my period when I got it, but menopause was simply like a black box,” she said.

The actress recalled that discussions around perimenopause and menopause only began when many of her close friends started experiencing symptoms themselves.

Calling the silence around menopause “astonishing” and “extremely unjust,” Lisa said women’s hormonal health continues to be severely underfunded and misunderstood globally.

“Menopause impacts all women. Yet it’s treated like a dark secret,” she told HealthandMe.

Lisa added that once she began researching the issue, she became increasingly frustrated by the lack of awareness and medical attention surrounding menopause and hormonal health.

Menopause Not Getting Enough Attention

The actress said that after moving to Dubai, she began openly discussing menopause on social media, despite initially worrying about public reaction.

“Sometimes in social settings, women would almost shut down or turn away and say, ‘Don’t talk about that.’ But when I put it on social media, maybe it permitted a lot of other women to also find a place to have a conversation or a community,” she said.

To bring about change where women can speak freely about the topic and seek treatment early, Lisa has co-founded NuHer, a science-backed health clinic and platform dedicated to midlife care for women. It is designed to support perimenopause and menopause through personalized medical treatments, clinical psychology, and nutritional guidance.

When asked why she chose to focus on menopause and women’s hormonal health, the Four More Shots Please! actress stated, “Menopause is simply not getting the attention that it needs. Women are struggling to get the care that they need and understand their options.”

Lisa explained that while awareness around cancer has steadily improved in India since her multiple myeloma diagnosis in 2009, menopause remains “the next taboo or frontier.”

According to Lisa, NuHer aims to create a safe, science-backed space where women can access support without judgment or dismissal.

“We need a place where women can be heard, where they’re not dismissed, where they’re not gaslit, where they receive all the right science and the options they can choose for this journey,” she told HealthandMe.

She also criticized the tendency to dismiss menopausal symptoms as a “normal” part of aging without offering support or treatment options.

“Women are not broken. Menopause is not a disease like cancer that has to be cured. But women need support. We don’t need to normalize suffering,” Lisa said.

Menopause Is 'Stepping Into Our Power Age’

Speaking about aging and post-menopause life, Lisa argued that society often dismisses older women despite what she described as a biologically important phase of life.

“We’ve had terrible PR as aging women. We are dismissed and considered irrelevant when actually we’re stepping into our power age if we know how to take care of ourselves,” the acclaimed actress told HealthandMe.

However, the problem arises when menopause is left unaddressed, and the hormonal changes cause long-term health impacts, including bone health, heart disease risk, and possibly dementia.

“The problem is with the drop in hormones. If you don’t have strategies and lifestyle changes to support yourself post-menopause, you become a frail woman. Your bones suffer. You’re more prone to heart disease and possibly even dementia,” she said, urging more women to seek medical help during menopause and not suffer in silence.
