Obesity has long been established as Risk Factor for CancerEspecially when it is stored in certain areas of the body.
Now a new study suggests that a greater waist circumference is a greater risk factor than a body mass index (BMI) Cancer associated with obesity – But only for men, not for women.
The results published in the magazine of the National Cancer Institute will be presented in May at the European Obesity Congress in Malaga, Spain.
BMI – This is the wrong way to measure obesity, the researchers say
The study was headed by Dr. Ming Son, Dr. Joseph Fritz and Dr. Tanja from Lund University in Sweden.

Researchers analyzed data from 340,000 Swedish people on average 51 years, whose BMI and waist circumference were conducted from 1981 to 2019, according to a press release.
Then they compared this statistics with diagnosis Extended from the Swedish River Register.

For 14 years, there were 18 185 obese cancer diagnoses among patients in the study.
For menThe increase in the waist circumference is about 11 cm, leading to 25% of the higher risk of obesity.
It was a bigger risk factor than an increase in BMI, which increased the chances of 19%.
For men, the waist circumference is about 11 cm, which is 25% higher risk of obesity. (Istock)
The study found that for women an increase of about 12 cm in the waist circumference and an increase in BMI was linked to 13% more cancer risk.
Cancer associated with obesity include esophageal cancer (adenocarcinoma), stomach (cardi), gut, rectumLiver/intrapecular bile ducts, gallbladder, pancreas, mammary gland (postmenopausal), endometrium, ovary, renal carcinoma, meningia, thyroid and multiple mioloma.
“BMI is an indicator of body size, but does not give information about the distribution of fat, whereas the waist circumference is proxy, more closely related to the obesity of the abdomen.”
Overall, the researchers found that the waist circumference is a more accurate cancer predictor than BMI.
“BMI is an indicator of body size, but does not give information about the distribution of fat, whereas the waist circumference is proxy, more closely related to the obesity of the abdomen,” they wrote.
“This difference is crucial because the visceral fat that accumulates around the abdominal organs is more metabolic and involved in adverse Health resultsIncluding insulin resistance, inflammation and abnormal blood fat. Thus, people with similar IPP may have different risks of cancer with the differences in fat distribution. “
Why the difference between men and women?
According to the researchers, one of the potential causes of the mismatch of gender inconsistency is that men are likely to retain fat viciously (in the abdomen), while women usually accumulate more subcutaneous fat (under the skin) and peripheral fat (in their hands and feet).

“Thus, the waist circumference is a more accurate measure of visceral fat in men than women,” the researchers write.
“This can make the waist circumference a stronger risk factor in men, and explain why the waist circumference adds information about a risk that exceeds BMI in men but not women.”
Researchers suggested that the combination of hip circumference with a waist circumference could give a more accurate assessment of visceral fat. (Istock)
Excess fat is also associated with an increase in insulin levels than the womenThe researchers noted that the waist circumference could be more strongly related to the risk of male cancer.
“The diversity is how the waist and BMI circumference relates to the risk of cancer between men and women, emphasizing the complexity of obesity (excess fat) on cancer development,” the researchers write.

“This suggests that taking into account the biological and physiological differences between the sexes can be useful when assessing the risk of cancer. Further research It is necessary to study these gender differences. “
They also suggested that the combination of hip circumference with a waist circumference could give a more accurate assessment of visceral fat.

Dr. Mark Siguegel, a clinical professor of medicine at Nyu Langone Health and Fox News Senior Medical Analyst, did not participate in the study, but strengthened that BMI is “a good obesity but not the only”.
“Female fat contains a lot of inflammatory chemicals that act as carcinogens.”
“Obesity leads to inflammation, and inflammation correlates with many cancers, including breast and prostate and cancers gastrointestinal tract“He said Fox News Digital.
“Not surprisingly, the waist circumference in men can be a more accurate indicator if you measure properly, since the fat in the abdomen contains a lot of inflammatory chemicals that act as carcinogens,” the doctor said.

For women where the fat distribution is slightly different, Zigel agrees that “makes sense” to consider both the waist circumference and the hip circle, the Swedish study implies.
“The study discusses more than 300,000 people and is a new important certificate, but it is an observation, so it shows the association but not proof,” the doctor added.

Dr. Brett Osborne, Florida Neurosurgeon and longevity, also spoke in detail about different ways in which men and women keep fat.
“While women accumulate more subcutaneous fat – on the hips, hips and buttocks – men collect it around the waist, Deep inside the stomach, “said Osborn, who did not participate in the study, said Fox News Digital.
“It’s viscous fat and it’s metabolic toxic. It’s not just sitting there. It’s active as a gland, the release of inflammatory chemicals (cytokines), enhancement the level of insulinDisruption of hormones and laying the base of cancer cell growth. “
The workout three times a week is perfect, advised one doctor, adding: “Stability learning reduces visceral fat and inflammation.” (Istock)
Osborne emphasized once again that BMI is limited in its ability to accurately measure excess fat.
“For the first time, BMI does not take into account the muscular mass, so a short, chunky person with low percentage of fat in the body can be classified as overweight or obesity, if in fact everything is the opposite,” he said.
“Secondly, BMI does not tell you where the fat is in the body, and, as it turns out, this is what is important – at least in men.”
Minimize risk
To reduce the risk of cancer, Osborne recommends men to measure their waist to make sure they are in A healthy range. People can also track their visceral fat score on the medical -level anthropometry scale, he said.
“Understand that the fat in the abdomen is not just cosmetic – it’s carcinogenic.”
“Everything above 40 inches (102 cm) is a red flag,” he said Digital Fox News.
Workouts three times a week perfectly, advised by the doctor by adding “Teaching resistance Reduces visceral fat and inflammation. “

He said proper nutrition is also important. “Eat as your life depends on it – because it is so. Stop feeding the risk of cancer.”
“Understand that the fat in the abdomen is not just cosmetic – it’s carcinogenic,” Osborne added. “You may not feel it now, but the clock is interested. Visita fat is silent, aggressively and deadly – and it causes harm, even if your BMI is” normal “.
