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.
From childhood, many girls are taught to be agreeable, responsible and perfect in everything they do. They are praised for being obedient, hardworking and emotionally controlled. Over time, this expectation can shape behavior in ways that may quietly harm mental and physical health.
This pattern is often referred to as “Good Girl Syndrome”. While it is not a formal medical diagnosis, doctors say the effects of constantly trying to live up to expectations can be very real. The pressure to appear composed and capable all the time can lead to emotional suppression, chronic stress and eventually hormonal disturbances.
To understand how this pressure affects the body, NDTV Health spoke with Dr. Y. D. Meherprasad, Senior Consultant in Endocrinology and Preventive Healthcare at MGM Malar Hospital, Chennai, who says he has observed this pattern among many young women in his clinical practice.
Good Girl Syndrome describes a behavioral pattern where individuals, often women, feel compelled to meet expectations without showing weakness or stress. This can translate into people pleasing behaviour, fear of conflict and difficulty setting boundaries.
Dr. Meherprasad explains that constantly trying to maintain this image can create a persistent stress response in the body.
“Hormonal imbalances are being noticed in young Indian women associated with the Good Girl Syndrome, where women are always trying to meet expectations and are continuously successful, all without showing any signs of stress,” he told NDTV Health.
According to him, the problem arises when emotions are suppressed for long periods. “When women suppress emotions for long periods, the body remains in a state of constant stress response,” he said.
Emerging research in the field of psychoneuroendocrinology suggests that emotional stress can directly influence hormonal regulation in the body.
At the centre of this process is cortisol, the body’s main stress hormone. Normally, cortisol rises briefly during stressful situations and then returns to normal levels once the threat passes.
However, when stress becomes constant, cortisol levels can remain elevated for long periods.
Studies have shown that chronic high cortisol can disrupt reproductive hormones. One effect described in research is sometimes called “progesterone steal,” where the body prioritizes producing stress hormones instead of reproductive hormones.
Low progesterone levels can contribute to irregular menstrual cycles, acne and other hormonal symptoms that many young women experience.
Dr. Meherprasad says chronic stress may also contribute to metabolic changes. In some cases, it can mimic or worsen conditions such as Polycystic Ovary Syndrome (PCOS).
When cortisol levels remain high, the body releases more glucose into the bloodstream to provide energy for a perceived threat. If that energy is not used through physical activity, insulin levels rise to regulate blood sugar.
Over time, this can lead to insulin resistance, which is a key factor associated with PCOS. Women may experience abdominal weight gain, irregular ovulation and difficulty managing their weight.
The effects of prolonged stress do not appear overnight. They often show up gradually through subtle changes in the body.
Dr. Meherprasad says menstrual irregularities are one of the early warning signs. Some women may experience delayed cycles or even a temporary halt in ovulation.
Sleep disturbances are also common. Many women report difficulty falling asleep because their minds remain constantly active, leading to fatigue the next day.
Other symptoms may include mood swings, persistent anxiety, brain fog and difficulty losing weight despite maintaining a careful diet.
Dr. Meherprasad says addressing these hormonal issues requires both medical evaluation and lifestyle changes.
Regular hormone screenings can help detect issues related to thyroid function, insulin levels and reproductive hormones such as LH and FSH. Early treatment is important if conditions such as PCOS or thyroid dysfunction are present.
Equally important is addressing the emotional component of chronic stress.
“Hormonal imbalance is not only physical but also closely linked to emotional health,” said the doctor.
He recommends prioritizing adequate sleep, regular physical activity and practices such as yoga that help calm the body’s stress response. Creating space for emotional expression through journaling or therapy can also help reduce long term stress.
In a culture that often rewards perfection, doctors say it may be time to rethink the idea of the “perfect girl”. Sometimes, protecting one’s health begins with allowing space for imperfection.
Cancer deaths in the United Kingdom have dropped to their lowest recorded levels, according to new data from the charity Cancer Research UK. The figures show that cancer death rates have fallen by 11 per cent in the past decade, reflecting progress in early detection, screening, treatment and prevention.
Researchers estimate that around 247 people in every 100,000 in the UK now die from cancer each year. This is a significant decline from the peak recorded in 1989, when about 355 people per 100,000 died annually from the disease. Overall, that represents a 29 per cent reduction over the past few decades.
Experts say this steady improvement is the result of sustained scientific progress, improved healthcare systems and public health measures that target risk factors such as smoking.
The new data highlights falling death rates across several major cancers. Ovarian cancer deaths have dropped by 19 per cent over the past ten years, up to 2024. Lung cancer deaths have fallen by 22 per cent during the same period, reflecting the long-term impact of reduced smoking rates and better treatment options.
Deaths from stomach cancer have seen one of the most dramatic improvements, dropping by 34 per cent in the past decade. Bowel cancer deaths have decreased by six per cent, while breast cancer deaths have fallen by 14 per cent.
Other cancers have also seen notable declines. Cervical and prostate cancer deaths have both dropped by 11 per cent. Deaths from leukemia are down by nine per cent, while esophageal cancer deaths have fallen by 12 per cent.
Experts say improved diagnosis, new therapies and better awareness are playing a key role in these trends.
One of the biggest public health successes has been the decline in cervical cancer deaths. Since the 1970s, deaths from cervical cancer have fallen by around 75 per cent in the UK. Health experts attribute much of this progress to the national cervical screening programme run by the NHS.
Screening helps detect abnormal cells early, allowing treatment before cancer develops or spreads.
Another major contributor is the human papillomavirus vaccine, commonly known as the HPV vaccine. The vaccine protects against the virus responsible for most cervical cancer cases. It is routinely offered to schoolchildren in the UK, and since its introduction in 2008, at least 6.5 million young people have received it.
Public health experts believe the vaccine will continue to reduce cervical cancer rates in the coming decades.
Despite the overall progress, the data also shows worrying increases in deaths from certain cancers. Gallbladder cancer deaths have risen by 29 per cent, while deaths from eye cancer have increased by 26 per cent.
Liver cancer deaths are up by 14 per cent, and kidney cancer deaths have risen by five per cent. Meanwhile, death rates for thyroid cancer, pancreatic cancer and melanoma have remained largely unchanged.
Another important trend is that the total number of people dying from cancer continues to rise. This is largely due to population growth and an ageing population, as cancer risk increases with age.
Experts say the long-term decline in cancer deaths reflects decades of medical research and innovation. However, they stress that continued investment is necessary to sustain progress.
Cancer Research UK researcher Dr Sam Godfrey said the figures show the impact of scientific breakthroughs over many years. He has called on the government to support more clinical trials and ensure that NHS staff have enough time and resources to take part in life saving research.
Public health policies such as smoking bans, along with screening programmes and vaccines, are also credited with helping drive down cancer deaths across the country.

Are you in the habit of catching up on social media or news updates while sitting on the pot? A new study shows you may be "unintentionally" spending extra time and increasing your risk of developing painful hemorrhoids by 46 percent.
The study, published in the open-access journal PLOS One, explained that getting distracted by news or social media can increase pressure on sensitive anal tissues, which leads to hemorrhoids.
Hemorrhoids, also called piles, are swollen and inflamed veins around your anus or in your lower rectum.
"Using a smartphone while on the toilet was linked to a 46 percent increased chance of having hemorrhoids. We're still uncovering the many ways smartphones and our modern way of life impact our health,” Trisha Pasricha, from the Beth Israel Deaconess Medical Center in the US.
“It's possible that how and where we use them -- such as while in the bathroom -- can have unintended consequences," she added.
For the study, the researchers examined data from colonoscopies of 125 adults in America, and conducted an online survey to understand their lifestyle habits and behavior while using the toilet.
Two-thirds of the participants reported using their smartphones while on
the toilet. Compared with those who did not, endoscopists found that they had a 46 percent higher risk of hemorrhoids.
More than a third of bathroom smartphone users reported spending more than five minutes there during a single visit -- reading news (54.3 percent), or browsing social media (44.4 percent).
In comparison, just 7.1 percent of non-users reported staying that long.
"Smartphone use may unintentionally extend the time people spend sitting on the toilet. Sitting for longer periods could increase pressure on tissues in the anal region, which may contribute to the development of hemorrhoids,” the researchers said.
Pasricha suggested individuals leave smartphones outside the bathroom to understand the actual time it takes for a bowel movement.
"If it's taking longer, ask yourself why. Was it because having a bowel movement was really so difficult, or was it because my focus was elsewhere?" she said, calling for more studies.
Studies estimate that hemorrhoidal disease affects 40% of people all over the world, and it is one of the most common diseases in the anorectal region.
The two types of hemorrhoids are:
