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.

Parkinson's disease is a progressive, neurodegenerative movement disorder caused by the loss of dopamine-producing brain cells, primarily affecting people over 60. Apart from motor loss, the disease also causes cognitive decline, depression, anxiety and swallowing problems.

The first symptom may be a barely noticeable tremor in just one hand or sometimes a foot or the jaw. Over time, swinging your arms may become difficult and your speech may become soft or slurred. The disorder also causes stiffness, slowing of movement and trouble with balance that raises the risk of falls.

However, before clear symptoms begin to appear, Neurologist Rachel Dolhun says certain signs may help identify the onset of the disease decades before it is diagnosed.

“It’s important to stress that not everyone who has these symptoms goes on to develop Parkinson’s,” said neurologist Rachel Dolhun. “But we know that in some people, these can be some of the earliest signs," she told The Washington Post.

Here is what you should look out for:

1. Loss Of Smell

Loss of smell, or hyposmia, is a common and early non-motor symptom of Parkinson's disease, affecting up to 90 percent of patients. This symptom can significantly impact quality of life by reducing the enjoyment of food and diminishing appetite.

While strongly linked to Parkinson's, smell loss can also stem from other causes, including sinus problems, COVID-19, or aging.

2. Acting Out Dreams

Acting out dreams, known as REM Sleep Behavior Disorder (RBD), involves physically enacting vivid, often unpleasant dreams through shouting, punching, or kicking during sleep.

This typically happens because the brainstem fails to temporarily paralyze muscles during REM sleep. It is a strong early warning sign of Parkinson's disease, often appearing years or decades before motor symptoms. About 50 percent of people with Parkinson's experience RBD.

3. Constipation

Constipation is a very common and significant non-motor symptom of Parkinson's disease that is caused by nerve changes slowing gut muscles and potentially exacerbated by low activity and dehydration.

Constipation can also be caused by Parkinson's medications such as anticholinergics, amantadine and other common drugs such as opioids, iron/calcium antacids.

4. Dizziness As You Stand

The autonomic nervous system fails to properly constrict blood vessels or increase heart rate upon standing, often due to a lack of norepinephrine. This causes the autonomic nervous system to fail in regulating blood pressure. Over time, this leads to Neurogenic Orthostatic Hypotension.

Beyond dizziness, symptoms include blurred vision, weakness, fatigue, cognitive "fog," and "coat hanger pain" (pain in the neck/shoulders). Often times, patients experience dizziness in the morning or immediately after meals.

Diagnosing Parkinson’s disease is mostly a clinical process, meaning it relies heavily on a healthcare provider examining your symptoms, asking questions and reviewing your medical history. Various imaging and diagnostic tests used to detect disease includes CT scan, PET scan, MRI scan and genetic testing.

Beyond icy roads and fogged-up car windscreens, the coldest season can also bring on a painful condition that leaves the skin covered in red, itchy patches. Doctors have issued a warning about this lesser-known illness, which tends to worsen in low temperatures.

The condition, known as cold urticaria, affects around one in 2,000 people. It causes swelling and itching of the skin when it comes into contact with cold air, cold water, or even air conditioning. Red welts or hives can appear within minutes, and the discomfort may last for as long as two hours.

What Is Cold Urticaria?

Cold urticaria is an uncommon condition in which the body reacts abnormally to cold temperatures. It typically causes rashes or hives after exposure to cold air, water, food, or drinks. In some cases, symptoms can be more serious. According to the Cleveland Clinic, the condition may sometimes be linked to an underlying blood cancer or an infectious illness.

Griet Voet, head of a dermatology clinic in Ghent, Belgium, as per Express UK, said the condition is often confused with common winter skin problems such as eczema. “This is not just dry skin caused by cold weather, it is a genuine allergic reaction to cold,” she explained. In more severe cases, large areas of the body may be affected, particularly after swimming in cold water or spending extended periods outdoors. This can lead to intense itching, facial flushing, and even headaches, stomach pain, or fainting. Sudden temperature shifts, such as moving from a warm indoor space into cold outdoor air, can also trigger symptoms. Drinking ice-cold beverages may cause swelling of the lips, mouth, or throat.

Cold Urticaria: What Are The Symptoms Of This Disease?

Symptoms of cold urticaria differ from person to person and can range from mild to severe. They may be limited to a small patch of skin or spread across the entire body.

The most common sign is a skin rash that appears after contact with something cold. The rash usually develops once the exposure ends, as the skin begins to warm up.

The rash may include:

• Hives, bumps, or raised welts
• Itching
• Redness
• Swelling

• Fatigue
• Fever
• Headache
• Joint pain

• Fainting
• Heart palpitations
• A severe allergic reaction known as anaphylaxis
• Shortness of breath or wheezing

How Is Cold Urticaria Diagnosed?

A medical professional can often diagnose cold urticaria using a simple test. An ice cube is placed on the skin, usually on the arm, for a few minutes and then removed. If a hive or rash appears several minutes later, the result is considered positive.

In cases of familial cold urticaria, diagnosis may involve exposure to cold air for a longer duration.

Doctors may also suggest blood tests to check for any underlying illness or infection that could be contributing to the condition.

Health authorities have urged the public to stay alert to Nipah virus symptoms after doctors warned that up to 75 per cent of infected patients may not survive. The UK Health Security Agency (UKHSA) has classified Nipah as a “high priority pathogen” because of its severe fatality rate and the absence of any proven treatment.

In India, the federal health ministry has confirmed two cases in the eastern state of West Bengal. This has triggered large-scale containment measures, with local officials placing nearly 200 people who had contact with the infected individuals under quarantine.

In response, several Asian nations have stepped up airport checks and health surveillance for travellers arriving from India. Professor Paul Hunter, an infectious disease specialist at the University of East Anglia, said identifying Nipah cases at borders is challenging, as symptoms can take a long time to appear.

What Is Nipah Virus?

According to UKHSA, Nipah virus is a zoonotic infection, meaning it can pass from animals to humans. It can also spread through contaminated food or via direct human-to-human contact. The virus was first discovered in 1999 during an outbreak affecting pig farmers in Malaysia and Singapore.

Fruit bats, especially those belonging to the Pteropus species, are the virus’s natural carriers. Research shows that Nipah can also infect other animals, such as pigs, dogs, cats, goats, horses and sheep.

Nipah Virus Symptoms

• Sudden onset of fever or general flu-like illness
• Development of pneumonia and other breathing-related problems
• Swelling or inflammation of the brain (encephalitis) or meningitis

Symptoms usually appear between four and 21 days after exposure, although longer incubation periods have occasionally been reported. More severe complications, including encephalitis or meningitis, can develop between three and 21 days after the initial illness begins.

UKHSA has cautioned that between 40 and 75 per cent of people infected with Nipah virus may die. Those who survive can experience long-term neurological effects, such as ongoing seizures or changes in behaviour and personality. In rare instances, the virus has been known to reactivate months or even years after the first infection.

Nipah Virus: Can You Prevent It From Spreading?

For people travelling to regions where Nipah is known to occur, prevention largely involves reducing exposure risks:

• avoid contact with bats, their habitats, and sick animals
• do not drink raw or partially fermented date palm sap; if consuming date palm juice, make sure it has been boiled
• wash all fruits well with clean water and peel them before eating; avoid fruits found on the ground or those that appear partly eaten by animals
• use protective clothing and gloves when handling sick animals or during slaughter and culling
• maintain good hand hygiene, especially after caring for or visiting ill individuals
• avoid close, unprotected contact with anyone infected with Nipah virus, including exposure to their blood or bodily fluids

Nipah Virus Symptoms Can Be Transmitted Easily?

Many Nipah infections have been linked to eating fruit or fruit-based products contaminated by the saliva, urine or droppings of infected fruit bats. Human-to-human transmission can also occur through close contact with an infected person or their bodily fluids, according to Mirror.

Such transmission has been documented in India and Bangladesh, with cases often involving family members or caregivers tending to infected patients. At present, there is no specific, proven treatment for Nipah virus infection, and no licensed vaccine is available to prevent it.

So far, no Nipah virus cases have been reported in the United States or the United Kingdom.
