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.

The Rise of Robotic Joint Replacement: How Technology Is Transforming Orthopaedic Surgery

Updated Jul 18, 2026 | 01:00 PM IST

SummaryOrthopaedic surgery is undergoing a transformation with the advent of robotic joint replacement. Robotic Joint Replacement is revolutionizing orthopaedics with cutting-edge features.
The Rise of Robotic Joint Replacement: How Technology Is Transforming Orthopaedic Surgery

Joint replacement surgery was one of the most successful surgeries in modern medicine, allowing millions of people to enjoy the benefits of mobility and pain relief despite the debilitating effects of advanced arthritis and joint damage.

The use of robotic-assisted technology is ushering in a new era in orthopaedic surgery today. Robots are not taking the place of surgeons, but they are helping to improve accuracy in surgery, to aid in planning, and to help provide more personal care.

Robotic Surgery Supports, Not Replaces, the Surgeon

As an orthopaedic surgeon, I see patients all the time who think that the surgery is done by itself, the robot. In fact, this is a procedure that is performed by the surgeon and the robot.

The robot serves as an advanced surgical assistant, giving the surgeon real-time guidance and very accurate measurements, but all key decisions and surgical steps are still left up to the surgeon.

Precision Drives Better Joint Replacement Outcomes

Precision is the biggest benefit of robotic joint replacement. Each patient's anatomy is different and subtle differences in bone alignment, ligament balance and implant placement can affect the long-term success of a joint replacement. Robotic systems utilize detailed imaging and computer mapping to develop a plan for a surgery that is unique to the patient before or during the surgery. This will help to maintain a more accurate placement of the implant so that the joint can be more accurately recreated and moved as it is designed to move.

This accuracy can mean a clinically significant benefit. Correct positioning of the implant can minimize the need for excessive bone removal, enhance joint stability, balance the soft tissues, and possibly increase the duration of the implant's life. Many patients also find that they recover more easily, experience less post-operative pain, and are more confident in getting back to everyday life, but results vary depending on many factors such as overall health, rehabilitation and the severity of the joint disease.

Robotic technology is increasingly being applied in knee and hip replacement surgeries, especially for those suffering from osteoarthritis. Robotic assistance is a major advantage in knee replacement surgery due to the critical role accurate positioning plays in ensuring the function and satisfaction of the implant. Robotic systems offer continuous feedback, allowing surgeons to make accurate adjustments during the procedure, which would be difficult without them.

Who Is the Right Candidate for Robotic Joint Replacement?

But keep in mind that not all patients require robotic surgery. While the use of acetals and PEKK has become more common in recent years, conventional joint replacement is still an excellent treatment, having been used for decades with great success. There are a number of factors which influence the choice of robot assistance, such as patient anatomy, case complexity, surgeon experience and availability of suitable technology. However, just because there is a robot does not automatically equate to a successful outcome; the skill and experience of the surgeon operating the robot still plays the primary role in the success of surgery.

Another false belief is that robotic surgery has no risks. As with all surgery, there are risks associated with joint replacement which include infection, blood clots, stiffness, loosening of the implant or revision surgery. Robotic technology aids in a more accurate surgery, however, it cannot eliminate all complications. It's still crucial to carefully select the right patient, to perform a careful surgery and to provide full rehabilitation after the surgery.

The Future of Personalized Orthopaedic Surgery

The advancement toward personalized medicine is one of the most thrilling developments in robotic-assisted surgery. With the advent of modern technology, the surgeon is able to use more than a basic one size fits most implant and surgery planning to fit the individual patient's anatomy and functional requirements. This individualised treatment is designed to improve patient comfort, return the joint to a more normal movement and maximise the long term function.

The recovery from a robotic joint replacement is comparable to that of traditional surgery, but some patients may experience faster recovery from the surgery because the surgery has been conducted with greater precision on the soft tissue. Early mobilization, proper physiotherapy, pain management and following the proper rehabilitation protocols are all important, regardless of the use of robots or not. Surgery is just the start of the healing process.

Robotic technology is also revolutionizing the surgeon's education and training. Real-time data and guidance, coupled with advanced navigation systems, improve decision-making and consistency in implant placement during surgery. With the ongoing advancement of AI and machine learning, future robotic platforms can enhance surgical planning even more by forecasting patient-specific outcomes and supporting complex clinical decisions.

While these are great strides, technology should never replace the human element in medicine. While the latest in cutting-edge equipment is essential for a successful joint replacement, the experience of the surgeon, clinical judgment, communication and patient-surgeon relationship are all vital to the success of the procedure. Each treatment plan is a custom one that is based on both the technology and realistic expectations along with evidence-based care.

The patient should be knowledgeable about the surgery options, results to be expected, benefits to be accrued, and possible risks involved in the surgery. While robotic surgery is an important advancement in orthopaedics, it is just one part of a patient's care plan and is not a substitute for surgical skill.

Orthopaedic surgery is definitely going to be a more technologic future. Robotic assisted joint replacement is a major advancement toward more precise, personalized, and patient-centered surgery. Research is ongoing and technology is becoming more available to be used to help manage degenerative joint disease, and this role is likely to increase over time. Finally, the mission continues to be the same: to get patients moving, to alleviate pain, and to restore an active and independent life with confidence.

John Cena Blames 'Eye Mites,' Not Age, For His Blurry Vision

Updated Jul 17, 2026 | 09:00 PM IST

SummaryDemodex mites are tiny, eight-legged organisms that live naturally on human skin, particularly around hair follicles. Measuring just 0.15 to 0.4 millimetres, they are invisible to the naked eye but are present on the skin of almost every adult.

When John Cena started noticing blurry vision, he assumed it was simply part of getting older. But the worsening eyesight was also accompanied by redness, itchiness and crusting around his eyes.

“I had a lot of redness and itchiness, and every once in a while, waking up with eye crusties and stuff. At the same time, given my age — I'm 49 now — my vision was going a little bit, so I just figured it was par for the course. But because my vision was going, I needed to see if I needed glasses or prescriptions.”

Until then, Cena had delayed getting his eyes checked. He believed that the symptoms were caused by bright lights, excessive screen time or ageing.

However, an eye examination gave him a surprise. Cena learned that his symptoms were caused by Demodex blepharitis, a condition he says he had never heard of.

“Diagnosed with Demodex blepharitis, which I didn't even know existed.”

What Are Demodex Mites?

Demodex mites are tiny, eight-legged organisms that live naturally on human skin, particularly around hair follicles. Measuring just 0.15 to 0.4 millimeters, they are invisible to the naked eye but are present on the skin of almost every adult.

These microscopic mites feed on sebum (the skin's natural oil) and dead skin cells, helping remove accumulated debris under normal conditions.

How Do Demodex Mites Work?

Demodex mites are most active at night. They emerge from hair follicles after sunset because ultraviolet (UV) light is harmful to them. While people sleep, the mites feed, crawl and reproduce on the skin's surface.

They are also believed to be stimulated by melatonin, the hormone that helps regulate sleep, creating a unique relationship between humans and these naturally occurring organisms.

When Can Demodex Mites Become A Problem?

Although harmless in small numbers, Demodex mites can cause problems if they multiply excessively—a condition known as demodicosis.

According to Dr. Richard Locksley, professor of medicine at the University of California, San Francisco, an overgrowth of Demodex mites can contribute to:

  • Rosacea
  • Blepharitis (eyelid inflammation)
  • Acne-like breakouts
  • Itchy, inflamed skin

People with weakened immune systems are particularly vulnerable because their bodies may be less able to control mite populations. In addition, inadequate sleep may increase oil production, providing more nourishment for the mites.

Should You Be Worried?

For most healthy people, Demodex mites are a normal part of the skin microbiome and are not considered harmful. Problems generally arise only when their numbers increase significantly.

To help reduce the risk of overgrowth:

  • Wash your face every night with a gentle, non-comedogenic cleanser to remove excess oil and debris.
  • Remove eye makeup and false eyelashes before bed, as these can encourage mite buildup.
  • Get adequate sleep, since poor sleep may increase sebum production.
  • Consult a dermatologist if you experience persistent redness, itching or inflammation around the eyes or skin.

Common Sports Injuries and How to Prevent Them

Common Sports Injuries and How to Prevent Them by Dr Sumit Batra. Whether you're training for a marathon, playing pickleball with friends, or simply trying to stay fit at the gym, being active is one of the best things you can do for your health. But every sport is unique and places different demands on your body. Without the right preparation, even a fun weekend workout can leave you with an injury that keeps you on the sidelines. Often, I see people whose injuries could have been avoided by warming up properly, increasing their training slowly, and paying attention to pain. Many think the pain will go away on its own, but getting it checked early can help prevent bigger problems.

Several types of common sports injuries show up suddenly, while others build up over time. Ankle sprains are among the most common. They usually happen when the foot rolls awkwardly during running, jumping, or changing direction quickly. Simultaneously, Knee injuries are another common problem, especially in sports that involve sudden stops, pivots, or jumps, so the ligaments, cartilage, or tendons around the knee can be affected, making movement painful and unstable.

Muscle strains in the hamstrings and calves often occur when muscles are pushed harder than they're ready for. Skipping a warm-up or increasing the intensity of your workouts too quickly can raise the risk.

Athletes who play cricket, tennis, or volleyball, or who spend long hours swimming, may also develop shoulder pain due to repeated overhead movements. And then there are overuse injuries like tennis elbow, shin splints, and Achilles tendinitis, which develop slowly after repeated stress without enough recovery.

How to Reduce Your Risk

The good news is that most sports injuries can be prevented. Start every workout with a proper warm-up. Just five to ten minutes of light movement and stretching can help prepare your muscles and joints for exercise.

Strength training is equally important. Strong muscles support your joints, improve balance, and help your body absorb the impact of running, jumping, and lifting.

It's also important not to rush your progress. Whether you're preparing for a race or trying heavier weights, increasing the intensity little by little gives your body time to adapt safely.

Recovery deserves just as much attention as training. Good sleep, proper hydration, balanced meals, rest days, and well-fitting sports shoes all play a role in keeping injuries away.

Listen to What Your Body Is Telling You

Always listen to your body—it often gives warning signs before it's too late. Feeling sore after a challenging workout is completely normal. But pain that doesn't improve, swelling, difficulty putting weight on a limb, or restricted movement shouldn't be ignored. Getting the injury checked early often means a quicker recovery and lowers the chances of long-term problems. Sports injuries can happen to anyone, whether you are a seasoned athlete or someone who enjoys staying active on weekends. A little preparation, sensible training, and adequate recovery can go a long way in preventing them. And if something doesn't feel right, don't wait for it to get worse. Early care can make all the difference in getting you back to doing what you love.
