Obesity has long been established as risk factor for cancerespecially when stored in certain parts of the body.
New research suggests that a higher waist circumference is a higher risk factor of body mass index (BMI) for Cancer associated with obesity – But only for men, not for women.
The findings, published in the National Institute of Cancer, will be presented in May at the European Congress on Obesity in Malaga, Spain.
BMI is a wrong way to measure obesity, researchers say
The study was led by Dr. Ming Sun, Dr. Josef Fritz and Dr. Tanja, shares from the University of Lund in Sweden.

Researchers analyzed the data of 340,000 Sweden people on average 51 years, whose estimates of the extent of BMI and the profession were conducted between 1981 and 2019, according to a press release.
Then these statistics compared to Cancer diagnosis drawn from the Swedish Registry of Cancer.
During the 14 -year period, there were 18,185 diagnoses of cancer associated with obesity among patients in the study.
For menThe increase in the waist circumference of about 11 cm resulted in a 25% higher risk of cancer -related cancer.
It was a higher risk factor of increased BMI, which increased the chances by 19%.
For men, an increase in waist circumference of about 11 cm resulted in a 25% higher risk of cancer -related cancer. (East)
For women, an increase of about 12 cm of waist circumference and an increase in BMIs associated with 13% higher risk of cancer, the study showed.
Cancer relating to obesity include esophageal cancer (adenocarcinoma), stomach (cardia), colon, rectumliver/intrahepatic bile ducts, gallbladder, pancreas, breast (postmenopause), endometrium, ovary, kidney cell cancer, meningioma, thyroid and multiple myeloma, the edition is mentioned.
“BMI is a body size measure but does not provide information about fat distribution, while the waist circumference is proxy closer to the adipomicity of the abdomen.”
Overall, researchers have found that the waist circumference is a more precise Cancer Predictor than BMI.
“BMI is a body size measure, but it does not provide information about fat distribution, while the waist circumference is proxy closer to the adipomicity of the abdomen,” they wrote.
“This difference is crucial because the visceral fat, which accumulates around the abdominal organs, is more metabolic and involved in adverseness Health outcomesIncluding insulin resistance, inflammation and abnormal blood fat levels. Consequently, individuals with similar BMI may have different risks of cancer due to differences in fat distribution. “
Why the difference between men and women?
One of the potential reasons, unlike gender, according to researchers, is that men are more likely to store grease hanging viscerally (in the abdomen), while women generally accumulate more subcutaneous fats (under the skin) and peripheral fats (in arms and legs).

“Therefore, the waist circumference is a more precise measure of visceral fats in men than in women,” the researchers wrote.
“This can make the waist circumference a stronger cancer factor in men and explain why the waist circumference adds information about risk outside those that BMI has transmitted in men but not women.”
Researchers suggested that combining hip circumference with waist circumference in women can give a more accurate assessment of visceral fats. (East)
Excessive body fat is also associated with higher insulin levels in men than in womenThe researchers noticed, which could be a factor in the extent of the profession, which is more strongly associated with the risk of men’s cancer.
“Diversity in the way the waist circumference and BMI relate to the risk of cancer between men and women emphasizes the complexity of the influence of adipomity (excess body fat) on cancer development,” researchers wrote.

“This suggests that when assessing the risk of cancer, it could be useful given the biological and physiological differences between gender. Further research It is required to explore these sexual differences. “
They also suggested that combining hip circumference with waist circumference in women can give a more accurate assessment of visceral fats.

Dr. Marc Siegel, a clinical professor of medicine in Nyu Langon Health and Fox News, a senior medical analyst, was not involved in the studio, but increased that BMI “is a good indicator of obesity, but not the only one.”
“Abdominal fat contains a lot of inflammatory chemicals that act as carcinogens.”
“Obesity leads to inflammation, and inflammation is correlated with many cancers, including breast and prostate and cancer gastrointestinal tract“He told Fox News Digital.
“It is not surprising that the waist circumference in men could be a more precise indicator if it is properly measured, because abdominal fat contains a lot of inflammatory chemicals that act as carcinogenic,” the doctor noted.

For women, where the distribution of fat is slightly different, Siegel agrees that it makes sense to consider both the waist circumference and the hook, as the Swedish study suggests.
“The study studies over 300,000 people and a new reference is important, but it is observation, so it shows connection, but not proof,” the doctor added.

Dr. Brett Osborn, a neurosurgeon expert and longevity in Florida, also described in detail the different ways in which men and women prepare fat.
“While women accumulate more subcutaneous fat – on hips, thighs and buttocks – men packed it around the waist, Deep in the abdomen, “said Osborn, who was not involved in the studio, for Fox News Digital.
“This is visceral fat, and is metabolic toxic. It doesn’t just sit there. It is active, like the glands, secreting inflammatory chemicals (cytokines), lift Insulin leveldisrupting hormones and laying the foundation for growth of cancer cells. “
The strength training three times a week is ideal, one doctor advised, adding: “Resistance training reduces visceral fat and inflammation.” (East)
Osborn reiterated that BMI was limited in its ability to accurately measure excess fat.
“First, BMI not a factor of muscle mass, so a short, low -fat storage in stock can categorize as excessive weight or obese, when it is in fact the opposite,” he said.
“Second, BMI does not tell you where physical fat is, and as it turns out, this is what is critical – at least in men.”
Minimization of risk
In order to reduce the risk of cancer, Osborn recommends that men measure their profession to ensure that they are in A healthy range. People can also monitor their visceral fat result in the medical anthropometry scale, he said.
“Understand that abdominal fat is not just cosmetic – it’s carcinogenic.”
“Everything above 40 inches (102 cm) is a red flag,” he told Fox News Digital.
The strength training three times a week is ideal, the doctor advised, adding: “Training reduces visceral fat and inflammation. “

Proper nutrition is also important, he said. “Eat as if your life depends on it – because it is. Stop feeding the risk of cancer.”
“Understand that abdominal fat is not just cosmetic – it’s carcinogenic,” Osborn added. “You may not feel it now, but the clock is ticking. Visceral fat is quiet, aggressive and deadly – and causes damage even if your BMI is” normal “.
