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.

Irritable Bowel Syndrome (IBS) is a common but often overlooked gastrointestinal disorder; as a result, IBS is very prevalent, with less than 15% being diagnosed.

Individuals frequently experience recurrent symptoms such as bloated abdomen, abdominal pain, gas, diarrhea, or constipation, and normalize these symptoms over time or attribute them to "something they ate" or everyday stresses. Therefore, IBS remains undiagnosed for many years.

Why Diagnosis Is Often Delayed

One reason for this delay in being diagnosed is that the symptoms occur intermittently. It is also important to note that the presentation of these symptoms is inconsistent and unpredictable; there may be episodes where the IBS can last many days, and then completely resolve, thus providing a false sense of relief. Therefore, many individuals choose to delay consulting with a physician due to their belief that the symptoms they are experiencing are not serious.

Stigma Around Digestive Health

Another contributing factor is that there is still a degree of reluctance or discomfort associated with discussing problems related to the gastrointestinal tract openly; this only further complicates under-reporting statistics.

A ‘Functional’ Disorder Adds to Confusion

Finally, IBS is a functional disorder. Therefore, routine diagnostic testing will not reveal any visible abnormalities. Many patients may assume that the symptoms they are experiencing are not "real" or are not significant enough to warrant seeking medical attention, even though the discomfort they experience can be quite significant and affect their daily lives.

If you continually ignore symptoms of IBS, it will hurt your quality of life, productivity, and mental health. If you have persistent discomfort, you are likely to develop anxious feelings about eating, socializing, and travelling. Furthermore, if you don't manage your symptoms, you may experience a combination of untreated IBS with one or more other illnesses that are either gastrointestinal or metabolic; consequently, establishing the correct diagnosis for your IBS will be increasingly difficult as time goes on.

Why Early Action Matters

It is of the utmost importance to identify and respond to early warning signs of IBS as quickly as possible. A thorough evaluation can rule out other illnesses and provide a pathway for appropriate management, including dietary modifications, stress management techniques, and, if necessary, medical treatment.

Once you address your IBS, you will experience better control of your symptoms and eliminate the long-term consequences of IBS, both physically and psychologically.

Colorectal Cancer is not only one of the most common and deadly cancers, but is also one of the most preventable ones.

Unlike many other cancers, patients have a clear window of opportunity to stop it before it even begins. Almost always, these cancers start as small growths called polyps or precancerous lesions on the inner lining of the colon or rectum.

There is a long interval of time before polyps develop into cancer. During this time, they can be removed if they are identified. If a doctor removes a precancerous polyp during a routine screening, they would not only have nipped the cancer in the bud, but would have also prevented it from occurring.

However, there is a persistent taboo surrounding discussing bowel movements and other risk factors, and public understanding of its symptoms and crucial screening procedures frequently lags.

Dr Jeremy Clark, a consultant general surgeon specializing in colorectal diseases at Nuffield Health in Brighton, has underscored five critical warning signs the public must recognize, The Independent reported.

1. Blood in stool

“Passing blood when you go to the toilet is a worrying feature that you should flag to your GP,” Clark said, adding that the color can vary from bright red to almost black.

“If you see blood in the stools, particularly darker-colored blood or blood that’s actually mixed in with the stools, just once, and it’s significant, that should be reported to your doctor straight away. Don’t wait for that to keep on happening,” he added.

2. Changes in Bowel Habits

Dr. Clark stated that although more constipation may not be a risk factor, any sudden changes in bowel movements that last for a couple of weeks and do not go back to normal must be checked.

“If your bowels go from working once a day like clockwork, and then suddenly you’re going two or three times a day, and the bowels are a bit looser, that’s something that needs to be looked into,” the expert added.

3. Abdominal pain

Dr Clark highlighted that bowel cancers can cause abdominal pain, even in the initial days.

4. Bloatedness

The feeling of being 'quite often’ bloated may also indicate that something is going wrong in the bowel, Dr. Clark said.

5. Unexplained weight loss

Bowel cancers can impact digestion and cause weight loss

Dr Clark said that as these symptoms are common with other conditions, such as hemorrhoids or irritable bowel syndrome (IBS), people often ignore or easily dismiss these symptoms. He urged patients not to ignore and visit their doctor if they notice any of these symptoms.

What Is Colorectal Cancer?

The American Cancer Society notes that colorectal cancer is a cancer that starts in the colon or the rectum. Colorectal cancer impacts around 1.9 million people every year, noted the World Health Organization (WHO) as per its 2022 data.

It is a disease of the large bowel and a type of cancer that originates from the rectum or colon. A person's colon, cecum, rectum, and anus make up the large intestine.

According to experts, if you are above 45 years of age or have high-risk factors, you need to take the initiative to be screened.

The FIT (Fecal Immunochemical Test) is a simple, non-invasive at-home stool test kit that can collect a small sample of your feces, which can then be tested.

“If it comes back as positive, that means there is blood in your stools which needs to be investigated,” Clark said, adding that the next step is typically the Colonoscopy – the gold standard.

Despite increasing access to healthcare, there is a lack of awareness when it comes to optional vaccines for children. Here, the expert guides parents regarding this. Parents should prioritise their child's health and ensure they are vaccinated without fail. So, learn more about these optional vaccines and make informed health choices when it comes to your children. Vaccines are important for a child’s well-being. Are you aware? In India, childhood vaccines are classified into two categories – those included under the government’s UIP (Universal Immunisation Programme) and those termed as “optional vaccines”.

Dr Amar Bhise, Consultant – PICU (Paediatric Intensive Care Unit), Neonatology and Paediatrics, Motherhood Hospitals, Lullanagar and Kharadi, Pune, spoke about ‘optional vaccines’. The expert also answered FAQs on which vaccines are of utmost importance for children and why timing matters.

What are ‘optional vaccines’?

“Parents should understand that optional vaccines are those that protect against additional infections not covered under the national schedule. These include vaccines for diseases like rotavirus, hepatitis A, chickenpox, influenza, and human papillomavirus. Though labelled optional, many of these vaccines play a crucial role in preventing illnesses that can lead to complications such as severe dehydration from rotavirus, liver inflammation from hepatitis A, and pneumonia or serious flu-related illness from influenza, hospitalisation, or long-term health issues,” said Dr Bhise.

UIP vaccines vs optional vaccines

There is a difference between UIP vaccines and optional vaccines. The reason they are not part of the UIP is often related to cost, prioritisation, and public health logistics, rather than a lack of importance. For example, the rotavirus vaccine helps prevent severe diarrhoea in infants, which can cause hospitalisation. Likewise, the HPV vaccine is important in preventing cervical cancer later in life. These benefits make such vaccines highly valuable, even if they are not universally provided.

Vaccines like the pneumococcal vaccine help prevent serious infections such as meningitis and bloodstream infections, especially in young children. This highlights that “optional” vaccines often protect against conditions that can become severe if left untreated.

Is timing important for vaccinations?

Dr Bhise said that another important aspect parents should consider is timing. Many optional vaccines are age-specific and work best when given within a recommended window. Delaying them may reduce their effectiveness or leave children vulnerable during crucial developmental years.

So, “optional” does not mean they are unnecessary, and it is not advisable to avoid including them in the vaccination schedule. In fact, with changing lifestyles, urban exposure, daycare attendance, and increased travel, children now have higher chances of suffering from serious infections. Vaccines, including influenza vaccines, which need to be taken annually, can help prevent seasonal illness and complications, particularly in young children or those with weak immunity. Chickenpox can cause severe skin infections or pneumonia in some cases, and can disturb parents’ peace of mind. Hepatitis A can affect a child’s overall health.

Parents should not worry, as these vaccines are safe and effective. These vaccines will safeguard children against preventable diseases. Making informed decisions can help parents ensure their child stays healthy.
