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.

World Parkinson’s Day is observed every year on April 11 to raise awareness about the progressive, neurodegenerative movement disorder caused by the loss of dopamine-producing brain cells.

People suffering from Parkinson’s face problems in motor movement, tremors, stiffness, and impaired balance. As symptoms progress, people may have difficulty walking, talking, or completing other simple tasks.

The condition primarily affects people over 60, but is now increasingly being seen in young adults. Apart from motor loss, the disease also causes cognitive decline, depression, anxiety, and swallowing problems.

World Parkinson's Day 2026: Origin

Parkinson's Day is observed on the day that marks the birthday of James Parkinson (born in 1755). The London-based doctor was the first to describe Parkinson as a medical condition in 1817, in his famous ‘Essay on the Shaking Palsy’. In 1997, the day was officially established by the European Parkinson’s Disease Association.

World Parkinson's Day 2026: Theme

The theme of World Parkinson's Day 2026 is "Bridge the Care Gap." It reflects a critical challenge that persists despite advances in medical research: many people living with Parkinson's still lack consistent access to specialist care, affordable treatment, and integrated support systems.

The day also aims to raise awareness about neurodegenerative diseases by educating the public about Parkinson's symptoms, causes, and available care.

Global Burden of Parkinson’s

Parkinson's disease affected 11.9 million people in 2021 and will affect 25.2 million people globally by 2050, representing an alarming 112 per cent rise.

According to a 2025 study released by The BMJ, this rise is mainly due to population aging and hence ranks as one of the most rapidly growing neurological disorders based on prevalence and disability. This alarming increase necessitates immediate global health interventions, research innovation, and policy reform to counteract its effects on people and health systems globally.

In addition, lifestyle differences, genetic susceptibility, and environmental exposures can also lead to regional variation in prevalence.

What Happens To Your Brain In Parkinson's Disease?

Parkinson's Disease affects various brain regions, but the primary symptoms arise from the degeneration of neurons in the substantia nigra, a region near the brain's base. This area is crucial for producing dopamine, a chemical messenger essential for smooth and purposeful movement. Research indicates that by the time Parkinson's symptoms become evident, patients have typically lost 60 to 80% or more of these dopamine-producing neurons.

Additionally, individuals with Parkinson’s disease experience a reduction in nerve endings that produce norepinephrine, a neurotransmitter responsible for regulating many involuntary bodily functions, such as heart rate and blood pressure. This loss may account for some non-movement-related symptoms of Parkinson’s, such as fatigue and fluctuations in blood pressure.

How to Prevent Parkinson's

Though there is no cure for Parkinson's disease yet, studies indicate that some lifestyle elements have the potential to shape its incidence and progression.

• Physical Activity – Engaging in regular exercise has been linked to a reduced risk of Parkinson’s, potentially due to its neuroprotective effects.
• Diet and Nutrition – A balanced diet rich in antioxidants, omega-3 fatty acids, and plant-based nutrients may support brain health.
• Environmental Factors – Exposure to pesticides, heavy metals, and air pollution has been associated with an increased risk, suggesting a need for improved public health measures.

Indian Actress Dipika Kakkar, battling liver cancer, underwent another surgery last month for a 1.3 cm cyst that reappeared.

Best known for her role as Simar Bhardwaj in the hit TV show Sasural Simar Ka, Dipika underwent a major tumour-removal surgery in June 2025. She also undertook chemotherapy

In her latest vlog, Dipika shared that the unexpected recurrence has left her feeling anxious and overwhelmed as doctors evaluate the next course of treatment.

"The recurrence that happened with the 1.3 cm cyst has shaken me. I am a little scared now that it shouldn't happen again. I have started dieting, but I feel anxious," she said.

HealthandMe spoke to health experts to understand why cysts recur in liver cancer patients and how it's important to keep monitoring them.

According to health experts, a biannual liver scan is imperative, and it can detect signs of cysts.

“Simple cysts less than 2-3 Cm can be observed with repeat scans every 6 months to 1 year. Suspicious or malignant cysts need surgical resection and oncological treatment based on the histopathology and patient condition,” Dr Manjunath NML, Sr Consultant, Surgical Oncology and Robotic Surgeon, HCG Cancer Hospital, K R Road, Bengaluru.

What Are Liver Cysts? How It's Linked To Cancer

Liver cysts are like bags that are filled with fluid. They are usually not cancer. Most people who have liver cysts do not get cancer.

However, just because one has a cyst, it does not mean it's cancer.

“Cysts in the liver are typically harmless and unrelated to liver cancer. However, unusual types of cysts may suggest malignant changes that need further examination, particularly among risk groups,” Dr. Govind Nandakumar, Consultant – Gastrointestinal Surgery, Manipal Hospitals Hebbal, told HealthandMe.

The experts noted that cases of recurring cysts related to liver cancer are uncommon. But they occur because of

• the presence of cancerous cells,
• regrowth of the organ,
• chronic conditions like cirrhosis.

Are There Early Warning Signs Patients Should Watch For?

Many liver cysts do not cause any problems in the early stages. That is why regular check-ups with a doctor are important. If a cyst grows or becomes problematic, symptoms may begin to appear. These can include

• abdominal pain,
• bloating,
• nausea,
• weight loss,
• yellowing of the skin,
• fatigue.

Is Recurrent Cysts A Cause Of Worry?

Recurrent cysts can be effectively managed and treated over time. The recurrence does not necessarily imply the progression of the condition itself; however, more tests may be required to determine whether cysts are malignant or benign.

“Cysts with thick walls, septations inside, and solid components in them are more likely to be cancerous. If the cysts are large, they cause symptoms like pain, distension, and obstruction of the bowel or biliary tract,” Dr Manjunath said.

The experts explained that diagnosis can be achieved by scans like ultrasonography, Computerized Tomography CT or Magnetic Resonance Imaging (MRI). Suspicious cysts must be checked via biopsy to confirm malignancy.

While suspicious or malignant cysts require surgical resection and oncological treatment, symptomatic cysts, even if benign, may also require removal.

However, if a liver cyst is detected without suspicious features and is asymptomatic, it usually does not require any intervention, Dr. Manjunath noted.

What if the body whispers long before it screams? For many living with Parkinson’s disease, the earliest signs are not the tremors, but quieter changes, such as a diminished sense of smell, disrupted sleep, or gut problems. The challenge is that we are conditioned to look for the disease only once it becomes visible.

Parkinson’s disease, commonly referred to as a movement disorder, progresses slowly due to the destruction of the nerve cells in the brain.

To understand Parkinson’s disease, think of the brain as a command center where certain nerve cells produce dopamine, a chemical messenger that helps coordinate smooth movement. As these dopamine-producing cells gradually deteriorate, the brain’s signalling system gets disturbed, leading to slower movements, mistaken for normal ageing.

The majority of patients experience subtle early signs much before diagnosis, including a reduced sense of smell, sleep disturbances like insomnia, and persistent digestive problems like constipation. In these cases, timely intervention can reduce movement disability by roughly 40 percent.

Parkinson’s Treatment

Conventional treatment focuses on medications that boost dopamine levels, but over time, their effectiveness may decline. When drugs are no longer sufficient, doctors may recommend Deep Brain Stimulation (DBS), a surgical approach that works like a pacemaker for the brain and uses chest-connected electrodes to reset faulty signals causing stiffness and tremors.

Unlike fixed traditional stimulation, the advanced Adaptive DBS (aDBS) listens to brain signals in real-time to adjust therapy automatically. Its single threshold mode reacts instantly, boosting stimulation the moment brain signals hit a specific limit and turns it off just as fast once they improve.

Alternatively, its double threshold mode keeps stimulation steady within the safe zone," making only gradual tweaks if signals cross upper or lower limits. This smart system mimics the body’s natural rhythm to provide fluid symptom control while preventing overstimulation, ultimately helping you reclaim more "good" time and independence.

Parkinson’s Diet

There is no single ‘Parkinson’s diet,’ but certain food choices can help manage symptoms and overall well-being. A balanced diet rich in fruits, vegetables, and whole grains supports general health and may help reduce inflammation.

Plant-based flavonoids, present in berries, citrus fruits, and broccoli, which have antioxidant effects, can help protect brain cells from damage. Drinking enough water can support digestion and prevent dehydration.

Ultimately, small, consistent dietary choices, combined with medical guidance, can make a meaningful difference in managing symptoms.

Parkinson’s disease is a journey, and the earlier the signs are recognized, the better the condition can be managed. If you or a loved one is experiencing persistent changes in sleep, smell, or movement, do not wait for the symptoms to become overwhelming. Consulting a neurologist is the first step toward taking back control of your health.
