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.

While research shows women need more sleep than men due to brain function, hormones, and multitasking, females around the globe are struggling to get enough sleep, according to experts.

A 2016 study by the Sleep Research Centre at the UK’s Loughborough University found that women needed 20 minutes more sleep because of multitasking and performing more complex brain tasks during the day.

But, the American Academy of Sleep Medicine (AASM), revealed that an estimated 30 percent of women fail to get sufficient sleep.

Hormones, mood disorders, and caregiving responsibilities, coupled with professional pressures and stress, are the major reasons driving up insomnia and other sleep issues among women.

“Women around the world face a higher burden of sleep difficulties because their sleep cycles are tightly interlinked with hormonal shifts that occur throughout life,” Dr. Janhvi Siroya Shah, Sleep Specialist from the University of Bern, Switzerland, told HealthandMe.

Gender Gap In Sleep: Why Women Sleep Less

The gender gap in sleep is real, as revealed by the recent ResMed Global Sleep Survey 2026, which showed that 56 percent of women get a good night's sleep only four days or fewer per week, compared to 50 percent of men.

Women were also 48 percent more likely to report problems falling asleep than men (42 percent). More than 50 percent of women felt waking up not feeling rested for 1-2 nights per week or more, compared to 46 percent of men.

The study flagged stress or anxiety as the biggest barrier to consistent, quality sleep (39 per cent), followed by work-related responsibilities (37 per cent) and household duties (31 per cent) among women.

Speaking to HealthandMe, Dr. Kirti Kadian, from the Department of Pulmonary Critical Care & Sleep Medicine at AIIMS Bhopal, said: “Women experience disproportionate sleep challenges globally, largely because their bodies undergo repeated physiological transitions that influence how sleep is regulated.”

The experts cited the main reasons as

• fluctuations during menstruation,
• pregnancy,
• postpartum recovery
• menopause.

All these factors can alter mood regulation, increase nighttime alertness, and disrupt the architecture of sleep itself.

Dr Kadian said that hormonal fluctuations across the life course -- especially during the menopausal transition -- can affect circadian rhythm, airway stability, pain sensitivity, and the nervous system’s response to stress.

“When these biological changes coincide with external stressors, such as multitasking, emotional labor or caregiving demands, women become far more vulnerable to insomnia and unrefreshing sleep,” Shah said.

The prevalence of sleep disorders increases from about 16–42 percent in pre-menopause to around 39–47 percent in peri-menopause and up to 35–69 percent in post-menopause, indicating that sleep disturbances become more common as women progress through different reproductive stages.

“Declining levels of estrogen and progesterone can disrupt the body’s sleep regulation and trigger symptoms like hot flashes and night sweats, while reduced melatonin may make it harder to fall and stay asleep,” Dr. Kadian explained.

In addition, certain medical conditions that are more common in women, such as thyroid disorders, anemia, and autoimmune diseases, can also negatively affect sleep and overall health.

How Poor Sleep Affects Women

Poor sleep also significantly affects both physical and mental health, increasing the risk of

• metabolic disorders,
• cardiovascular disease,
• weakened immunity,
• persistent fatigue,
• reduced concentration,
• irritability,
• anxiety,
• depression.

How Women can Improve their Sleep

The Harvard Medical School suggested that to get a better sleep cycle women should:

• Create a sleep sanctuary by removing the television, computer, smartphone or tablet, from the bedroom.
• Cut down or limit afternoon naps to 20 to 30 minutes
• Avoid caffeine after noon
• Get regular exercise, but not within three hours of bedtime.

While early-stage research raised hopes of oral semaglutide (GLP-1 pill) slowing down the progression of Alzheimer’s disease, results of a new large-scale clinical trial have rendered it ineffective.

Evoke and Evoke+ -- the randomized, double-blind, placebo-controlled phase 3 trials conducted across 566 sites in 40 countries -- showed that semaglutide led to no significant difference after two years.

The findings, published in the Lancet journal, however, revealed that the popular weight loss drug can lead to significant reductions in several biological markers of Alzheimer’s disease.

Yet, it did not help slow the progression of the neurodegenerative disease, said an international team of researchers, including those from the University of California-San Diego.

"Oral semaglutide was not efficacious in slowing clinical progression in participants with early Alzheimer's disease," they said in the paper.

"Safety and tolerability of semaglutide in early Alzheimer's disease is consistent with studies in other indications," the team added.

The EVOKE and EVOKE+ trials

The studies are the first major phase 3 trials to investigate this possibility in people with early Alzheimer’s disease.

The researchers conducted the trial on about 3,800 patients aged 55-85 years. The patients received either up to 14 mg of oral semaglutide daily or a placebo pill.

After two years, no significant difference was seen in slowing down the cognitive disease's progression in patients taking semaglutide and patients taking the placebo.

"The results of the large evoke(+) trials do not support the efficacy of 14 mg/day of semaglutide given for up to 156 weeks in participants with biomarker-confirmed Alzheimer's disease in the MCI or mild dementia stage," the researchers said.

While “GLP-1 [drugs] have given us so many wonderful results," the trial results are "disappointing,” and “a setback for the field”, endocrinologist Daniel Drucker was quoted as saying to the Scientific American.

Drucker says there are many potential explanations why oral semaglutide didn’t work as hoped. The fatty-acid structure surrounding semaglutide might have prevented it from being able to penetrate certain brain regions, such as the hippocampus, which controls memory and cognitive function.

What Is Alzheimer’s Disease

Alzheimer's disease is a progressive neurodegenerative disease characterised by gradual cognitive and functional decline.

It is one of the most common forms of dementia and mostly affects adults over the age of 65.

Over seven million people in the US, 65 and older, live with the condition, and over 100,00 die from it annually.

The disease is believed to be caused by the development of toxic amyloid and beta proteins in the brain, which can accumulate and damage cells responsible for memory.

Early symptoms of Alzheimer's disease include forgetting recent events or conversations. Other signs include:

• losing or misplacing things
• getting lost when walking or driving
• being confused, even in familiar places
• losing track of time
• difficulties solving problems or making decisions
• difficulties performing familiar tasks
• misjudging distances to objects visually.

In the year 1947, on the remote Scottish island of Jura, George Orwell sat hunched over a typewriter in a farmhouse, engaged in a desperate race against time to finish his masterpiece, 1984, while a ‘slow-motion plague’ consumed his lungs.

The man who was born in Motihari, Bihar, was suffering from tuberculosis. He would cough up blood and frequently collapse out of sheer exhaustion, even as he typed the final warnings of a dystopian future. He finished the book in December 1948 and died just over a year later.

Orwell’s story is a haunting reminder that TB has always been a disease of the displaced. As we approach World Tuberculosis Day this year with the theme ‘Yes! We Can End TB: Led by countries, powered by people, we face a sobering reality.

We have the modern tools that Orwell lacked, but the global narrative remains trapped in an outdated cycle where technological potential far outstrips operational reality. To end this disease, we must stop viewing TB through a narrow clinical lens and start addressing the systemic inefficiencies that leave out millions.

From Years to Months: The Scientific Revolution

For decades, a diagnosis of drug-resistant TB (DR-TB) was a near-death sentence even with treatment. Patients faced a grueling 18 to 24-month treatment regimen involving thousands of pills and daily painful injections that often caused permanent side effects like deafness.

With the introduction of the BPaLM regimen (Bedaquiline, Pretomanid, Linezolid, and Moxifloxacin), this tide seems to have turned. The all-oral four-drug treatment, touted as a medical miracle, has slashed recovery time for drug-resistant strains to just six months.

However, even a magic pill cannot overcome a broken system. We must distinguish between clinical success and social success. A patient might technically be cured of the bacteria, but if they lose their job or suffer from social stigma during those six months, the system has still failed them.

The Gender Gap: Why Men Remain Elusive

Statistically, men bear a higher burden of TB, yet they are often the hardest to bring into the care net. According to the World Health Organization (WHO), men account for approximately 55 per cent of all TB cases globally, compared to 33 per cent for women and 12 per cent for children.

This is not a biological accident; it is a structural failure. Gendered social norms often prevent men from seeking care until the disease is advanced. As primary earners, the prospect of losing wages – combined with the stigma of diagnosis – creates a powerful disincentive to visit a clinic. To be truly people-centered, we must move away from static clinic hours and towards flexible, community-based care that reaches men at places where they work.

The Silo System and the Economic Reality

Treating TB in isolation is an outdated strategy. We see patients suffering from a double burden because TB is usually accompanied by diabetes, malnutrition, or even HIV.

• Diabetes: Increases the risk of TB by two to three times.
• HIV: People living with HIV are 16 times more likely to fall ill with TB.

Despite this, our medical systems remain stubbornly reserved. A patient is often forced to navigate fragmented clinics that rarely communicate. Integration is the only way to ensure we treat the whole person, not just the pathogen.

The Human Cost of Cure

The path forward requires us to acknowledge that we cannot end TB by looking only at the lungs; we must look at the lives of those affected. The end of TB is a matter of leadership and courage to fix the systems that hold medical science back.

As we look towards World Tuberculosis Day, let us not just renew our commitments; let us hold our systems to account. The human cost of cure is currently too high, not because of the medicine, but because of the world in which the medicine is delivered.

As we honor World Tuberculosis Day, let us ensure that no one else has to choose between finishing their life’s work and surviving a curable disease. Curing tuberculosis is no longer a biological mystery; it is a test of our collective humanity.
