Obesity can lead to more than 10000 types of cancer
According to a study, more than 10,000 types of cancer are be caused by obesity.
The amount of estrogen circulating in the body increases due to excessive fat, which in turn disrupts how the body processes insulin. All this is linked to higher risk of cancer.
It also triggers low-grade inflammation in the body, which is increasingly being found to play a role in cancer.
According to the researchers, people should remain physically active and should maintain normal body weight throughout life.
Weight gain after a cancer diagnosis is also likely to affect the outcome, say researchers.
"An increasing number of studies suggest that regular physical activity improves cancer survival, even among survivors who are overweight or obese,” the Independent quoted AICR researchers as saying.
"Public awareness of the link between obesity and cancer risk is alarmingly low," said Alice Bender, MS, RD, and Nutrition Communications Manager at AICR.
"We are working towards a day when obesity is right up there with tobacco in the public eye," Bender added.
The AICR estimates show that excess body fat is linked to 49pct of endometrial cancers, 35pct of esophageal cancers 28pct of pancreatic cancers, 24pct of kidney cancers, 21pct of gallbladder cancers, and 17pct of breast cancers and 9pct of colorectal cancers.
