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.

Right now, days' stress no longer comes in bouts; bouts have been turned to a continual rhythm. Deadlines, working overtime, staring at computer screens, lack of sleep, and daily tensions, together with environmental pollution, have resulted in what physicians have started to call the "always stressed" generation. Things like cortisol, the body's primary stress hormone, which is linked to changes in female fertility, albeit subtly, are being blamed more and more nowadays.

Is cortisol making women infertile?

In an interview with Health and Me, Dr. Rubina Pandit, Fertility Specialist, Nova IVF Fertility, Basaveshwaranagar, spoke about the impact of cortisol on fertility in women.

Cortisol is a great help when the body is responding to stress. Among other functions, it regulates energy, metabolism, and immunity. The trouble begins with stress that is sustained for a long time and cortisol levels that remain high continuously. Then it starts to cause disruptions to reproductive health.

The latest studies conducted in 2025 and 2026 indicate that stress over a long period may affect the hormonal balance required for ovulation. A high level of cortisol also changes the brain signals that are responsible for the regulation of the ovaries and that can cause irregular periods or even absence of ovulation. In other words, chances for natural conception will be diminished if ovulation doesn't occur regularly.

More intriguingly, recent research has discovered some new findings about the impacts of stress on infertility. According to a 2026 study, cortisol hormone levels could modify the uterine environment and influence the genes that facilitate embryo attachment and development. In this case, the effect of stress could not only affect ovulation but also interfere with the successful growth of fertilised embryos.

Infertility and chronic stress: The link explained

Another area of study that researchers have focused on is the possible connection between infertility and chronic stress. Recent scientific studies suggest that women under constant stress have markers that signal reduced ovarian functioning. Moreover, prolonged stress is known to negatively affect sleep, libido, and even romantic relationships of couples.

That said, it is worth mentioning that stress is unlikely to be the only reason for infertility issues. However, stress usually exacerbates all other reproductive problems and makes them very hard to manage. The emotional load is, in fact, one of the least acknowledged side effects of stress. A lot of women who are treated for fertility issues complain about being stressed. And due to this stress, some of them even give up on their treatment. This is a direct indication that mental health and fertility work in tandem.

The main point is that fertility is more than just hormones or medical intervention; it is the overall well-being that matters. Changing stress levels by having good sleep, exercising regularly, practicing mindfulness, or even getting professional help can have a great impact. In a generation that is always switched on, learning how to slow down might be one of the most important steps toward improving fertility.

Spending hours at work is one thing, but spending countless hours at the same desk just to meet deadlines is a habit that not only takes a toll on mental health but also on physical well-being. That being said, the rising incidence of spine problems is concerning—once a problem of the elderly, it is now affecting younger people as well. However, due to the age factor, several people tend to ignore spine problems, but they continue to worsen silently. In such a scenario, early and regular health checks can help prevent pain, stiffness, and long-term disability.

Dr Harshal Bamb, Senior Consultant and Spine Surgeon at Gleneagles Hospital, Parel, listed some of the key tests for the spine that can help with the early diagnosis of health problems. It is time to focus on spine health and improve quality of life.

Why have spine problems become common?

Currently, many people are struggling with spine problems. With long working hours, poor posture, excessive screen time, and a lack of physical activity, spine-related problems can steal peace of mind. Spine problems are conditions that affect the bones, discs, nerves, or muscles of the back and neck. These may include issues such as muscle strain, slipped or herniated discs, cervical or lumbar spondylosis, and spinal deformities such as scoliosis that can interfere with daily activities.

What are the symptoms of spine problems?

It is essential to seek help for signs and symptoms such as back or neck pain, stiffness, tingling or numbness in the arms or legs, reduced flexibility, and difficulty in standing or sitting for long periods. In more severe cases, it can also lead to weakness or nerve compression in patients. Timely awareness and routine checks can help prevent complications such as immobility, pain, nerve damage, and posture problems. If left untreated, spine problems can impact quality of life.

Health tests that can help diagnose spine problems

Dr Bamb, in an interview with Health and Me, spoke about the key spine health checks that can be helpful for people dealing with severe pain and strain.

1. Posture check: The expert will examine regular sitting and standing posture, especially during work hours. So, if you have back pain due to poor posture, then seek immediate help. Posture evaluation is important for everyone.
2. Pain monitoring: The expert will track any recurring back or neck pain instead of ignoring it.
3. Flexibility test: Check your ability to bend, twist, and move without discomfort. Do the range of motion (ROM) test as suggested by the doctor.
4. Nerve symptoms check: Watch for tingling, numbness, or weakness in the limbs. A neurological examination (sensory and motor assessment) will be conducted.

Evaluating lifestyle habits such as long sitting hours, obesity, and lack of exercise is also key to understanding spine health. Spine risk assessment or even musculoskeletal risk screening is also important. So, take these tests and keep your spine healthy.

Just like regular health check-ups for the heart, joint and spine check-ups are also important. Maintaining good posture, staying active, stretching, exercising daily, and seeking timely medical advice can help to protect the spine. Do not engage in strenuous activities mindlessly and pay attention to your spine.

Vaccines are like insurance; they’re important for health as well as safe to take, said Dr NK Arora, the former Chairperson and currently a member of the National Technical Advisory Group on Immunization, NTAGI.

NTAGI is the highest advisory body on immunization in the country, which consists of independent experts who provide recommendations on vaccines after reviewing data on disease burden, efficacy, and cost-effectiveness of vaccines.

As part of the ongoing World Immunization Week, Dr. Arora, the Executive Director of The INCLEN Trust International, spoke in an exclusive interview with HealthandMe on the importance of vaccines.

Comparing vaccines to insurance, Dr Arora highlighted the importance of immunization for both the young and the elderly. He emphasized that vaccines provide preventive protection against serious diseases, much like insurance offers financial security before a crisis occurs. He also underlined that timely immunization across all age groups is essential to reduce disease burden, prevent outbreaks, and ensure long-term public health safety.

“What I will say is that vaccination is like insurance. This is insurance for our health. And so it ensures the health of our children, ensures the health of our women, and pregnant women. It will ensure the health of our adolescents where the vaccination is going on,” said the expert.

The expert also urged people not to waste their time with anti-vaccine rumors and noted that vaccines, approved and given in the public health system, are safe and free of cost. These are initiated only after rigorous trials.

“Please do not hesitate to take the vaccine,” he said, adding that “vaccines are developed after extensive studies, both before it is first used in human beings and then again in human beings. And safety is something of paramount importance”.

He said people must get a vaccine, not when sick, but when we are in good health, and importantly urged the need to dispel myths around vaccines.

“I would like to assure all my readers that all the vaccines which are approved and given in the public health system are safe. Occasionally, you will hear some misinformation, some rumor, and this needs to be dispelled. If you are not very sure, please contact your physician, the nearest physician who looks after you and your family, and get clarifications from them. Rather than putting your weight on social media news and hearsay from neighbors and others, please get it. But I again assure you that all the vaccines available in India today are very safe”.

World Immunization Week

World Immunization Week is observed every year from April 24 to 30. The theme for 2026 is ‘For Every Generation, Vaccines Work.’

According to the WHO, vaccines have saved more than 150 million lives over the past 50 years.

"That’s 6 lives every minute, every day, for more than 5 decades," the WHO said.

Currently, more than 30 life-threatening diseases and infections are prevented by vaccines.

However, 20 million children missed at least one vaccine dose in 2024, leaving far too many at risk of preventable disease.

Vaccination in India: Progress with Gaps

In India, vaccines have played a significant role in improving public health. The country's immunization campaigns have been key to eradicating polio and smallpox. It has also eliminated yaws and maternal and neonatal tetanus in India. In addition, child mortality rates, measles-rubella, and tuberculosis have also been considerably reduced.

As per an official government statement, full immunization coverage has risen from 62 per cent in 2015 to 98.4 per cent in January 2026.

The percentage of zero-dose children to the total population has declined from 0.11 per cent in 2023 to 0.06 per cent in 2024.

However, gaps remain in child vaccination. These include:

Only 76.4 per cent of children (12–23 months) are fully vaccinated (NFHS-5)

India accounts for 6.4 per cent of global zero-dose children and 49.2 per cent in South Asia.

In 2024, 909,000 children remained unvaccinated, while 454,000 were partially vaccinated.
