Your belly fat may up risk of cancer
In addition to the higher body mass index (BMI), those with increased abdominal fat are at higher risk of developing cancer, including breast and bowel cancer, especially in the elderly, researchers have warned.
Being overweight or obese is the leading preventable cause of cancer after smoking.
The results showed that for each increase of 11 cm in height, the risk of cancers related to obesity, such as breast, colon, uterus, esophagus (feeding tube), pancreas, kidney, liver, upper stomach (cardiac Gastric), gall bladder, ovaries, thyroid, etc., up to 13 percent.
The addition of about eight cm hips increases a 15 percent risk of developing bowel cancer.
“Our results show that BMI and body fat when exercised over the body may be good indicators of cancer risk associated with obesity, specifically fat around the waist may be important for certain types of cancer “Said lead author Heinz Freisling Scientific and the International Agency for Research on Cancer (IARC-WHO) in France.
The use of excess body fat can alter sex hormone levels, such as estrogen and testosterone, cause an increase in insulin and cause inflammation, factors that have been associated with an increased risk of cancer, the researchers explained .
In the study, published in the British Journal of Cancer, the team showed that three different measures of body size – BMI, waist circumference and hip size ratio – all expected a similar obesity-related cancer risk in women. old people.
“To better reflect the underlying biology in the game, we believe it is important to study more about BMI alone with respect to cancer risk.” And our research adds a better understanding of how people’s body shape could increase their risk, ” Said Freisling.
The researchers’ combined data of about 43,000 participants who were followed for an average of 12 years and over 1,600 people were diagnosed with obesity cancer.
