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.
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."
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.
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.
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 World Health Organization (WHO), notes that 36% of world's rabies deaths come from India, and a 2024 Lancet study notes that the country accounts for over one-third of global rabies deaths. When we spoke to Dr Aniket Mule, Consultant Internal Medicine at KIMS Hospital, Thane, he said that it is not just dog bites that lead to rabies, but it could happen from any rabies-susceptible animal. The first line of defense after you clear your wound immediately is to get the rabies vaccine. "Rabies vaccination is required for bites or scratches from any rabies-susceptible animal, including cats, monkeys, bats, foxes, and other wild mammals," he pointed out. As the country's apex court ruled and issued directives on stray dogs, focusing on public safety by ordering their removal, global health organizations, including WHO point out that this is not the right way to deal with rabies issue. Comprehensive methods including evidence=based strategies that center on mass dog vaccination is the key to the problem.
However, before this could be implemented, here's what you should know about dog bites and rabies.
Dr Mule points out that even when there are minor scratches, without bleeding, you must get a rabies shot. "Rabies can be contracted through broken skin. Such exposures still require medical evaluation and, in most cases, rabies vaccination."

Dr Mule points out that the rabies vaccine should be started as soon as possible. "Ideally within 24 hours of a bite or scratch. However, even if there is a delay of days or weeks, vaccination should still be started immediately as rabies has a variable incubation period," he says.
After the bite, the immediate medical attention involves rabies post-exposure prophylaxis or PEP, and with a tetanus booster. Some rabies vaccines also use saline water as the diluent to reconstitute the freeze-dried powder before injection.

The temperature of the vaccine matters. "Rabies vaccines are temperature-sensitive and must be stored between 2°C and 8°C. Exposure to heat or freezing can reduce vaccine potency. Poor cold-chain maintenance is a known reason for vaccine failure in rare cases," points out the doctor.
Dr Mule points out that in order to avoid such things happening, one must ensure immediate wound washing, timely vaccination, and correct use of Rabies Immunoglobulin or RIG. Rabies can come back if these following things occur:
Dr Mule points out that the vaccine should be given intramuscularly in the deltoid or upper arms for adults, as gluteal or buttock injections could lead to inadequate absorption and reduce effectiveness.
The exact schedule depends on vaccination history and the protocol followed.

Winter in India is often associated with sardio ke laddoo, but also with increasingly sedentary lifestyle, worsening air pollution, all of which leads to more time spending home than to going out, taking a stroll, working out and more. This is why as winter sets in, India also sees a quiet but consistent rise in non communicable diseases, or NCDs, conditions that now account for nearly two thirds of all deaths in the country. Heart disease, diabetes, thyroid disorders, fatty liver disease and arthritis continue to rise across age groups, driven by sedentary lifestyles, dietary excess and delayed diagnosis.
Winter can further aggravate these risks. Physical activity drops, calorie dense foods become routine, sunlight exposure reduces and metabolism changes. Studies and hospital data in India have repeatedly shown that heart attacks and strokes tend to spike during colder months. Blood vessels constrict, blood viscosity increases and cholesterol levels often rise. Blood sugar control also becomes more challenging, while joint pain and stiffness worsen for many.
Dr. Mayanka Lodha Seth, Chief Pathologist at Redcliffe Labs, says the problem is not seasonal food but seasonal neglect. “Traditional winter foods are not harmful on their own. The real risk comes from consuming them without understanding what is happening inside the body,” she explains. “Winter tends to mask symptoms while quietly worsening internal imbalances.”
With India already home to over 100 million people living with diabetes and a similar number estimated to be prediabetic, preventive testing becomes crucial. Doctors recommend five key tests that can offer a clearer picture of health before winter indulgence begins.
Diabetes is one of the fastest growing NCDs in India, and a large proportion of cases remain undiagnosed. Winter diets high in sugar and fat can trigger frequent glucose spikes. Testing fasting blood sugar and HbA1c helps identify early risk and prevents long term complications affecting nerves, kidneys and the heart.
High cholesterol is a major contributor to cardiovascular disease, which remains India’s leading cause of death. Reduced activity in winter often pushes lipid levels higher. A lipid profile helps assess heart risk and guides dietary and lifestyle moderation before damage sets in.
Non alcoholic fatty liver disease is increasingly common in India, even among younger adults. Excess sugar and fat intake during winter can worsen liver fat accumulation. Early liver testing can flag reversible changes before they progress to chronic liver disease.
Thyroid disorders affect millions in India, especially women, and often go unnoticed. Symptoms like weight gain, fatigue and cold intolerance are frequently brushed off as winter sluggishness. A simple thyroid test helps distinguish seasonal lethargy from hormonal imbalance.
Vitamin D deficiency is widespread due to limited sun exposure in winter, while Vitamin B12 deficiency remains common because of dietary patterns. Both deficiencies are linked to low immunity, muscle pain, bone weakness and worsening joint discomfort.
Dr. Seth adds, “Preventive diagnostic testing allows people to make informed choices. It helps them enjoy winter foods in moderation without unknowingly worsening an underlying condition.”
As NCD related healthcare costs continue to rise in India, early testing offers both health and financial protection. Winter comfort does not have to come at the cost of long term health. Staying informed may be the most effective preventive step this season.

Flu season is hitting hard this year, and the symptoms could feel relentless. People are suffering from rising fever, hacking cough, blocked and stuffy nose and sore throat. While many people get relief from Tamiflu, which is a prescribed antiviral medication that is used to treat or even to prevent illness, there are other alternatives available too.
Dr Ari Brown, a Texas based pediatrician and the author of Baby411 book series told CNN health that one of the most common complaints that she gets to hear from Tamiflu is vomiting. A 2023 study published in the Pediatric Infectious Disease Journal notes that 18% of people experienced vomiting with Tamiflu, as compared to 5% with Xofluza, an alternative.
“I’ve also had a few pediatric patients experience moodiness with Tamiflu, which is reported in the literature,” she said.

Tamiflu is usually gives to treat flu in people ages 2 weeks and older and to reduce the chance of getting the flu in people 1 year and older. The medicine could be administered in both form, liquid and capsules and usually taken twice daily for five days straight. This is prescribed for when flu is to be treated. However, when used for prevention, it is typically taken once for 10 days.
Xofluza: It is administered as a single dose tablet and is approved for ages 5 and older. This medicine can also be used to treat or to prevent the flu. While it costs nearly $200 for those without insurance, eligible patients can use coupons to lessen costs. Dr Brown points out that this medicine could have side effects like diarrhea and vomiting. However, the study aforementioned notes that for this, only 5% patients had vomiting symptoms, when compared with Tamiflu.
Dr Brown also said that Xofluza can stop viral shedding in one day, while Tamiflu could take up to three days. "Both antivirals will help reduce the duration of misery by couple of days," she pointed out.
Dr Brown also pointed out that overall, "Xofluza is rising in popularity over Tamiflu." “One dose. Fewer side effects. More insurances are covering the cost of it now and manufacturer coupon makes it less expensive than in previous years," she said.
Rapivab: This is another prescribed medication that is approved to treat flu. This could be administered for people ages 6 months and older. It has to be given by a health care provider, as it is given once as an intravenous infusion. It could cost up to $1,000 without insurance and most common reaction in adults is diarrhea.
Relenza: This flu medication is inhaled in powder form. It is administered through an inhaler device, which is to be used twice a day for five days straight. The prescribed drug is approved to treat flu in ages 7 and older and for preventative use, in ages 5 and older. It could cost about $90 without insurance.
It may have side effects like dizziness, allergic reaction, or irritation of the nose. It is not recommended for people who have breathing issues or have asthma.
