As many as 100,000 cases of cancer could be prevented in the U.S. each year if Americans get rid of their excess body fat.
The researchers estimate that excess body fat is the cause of 33,000 breast cancer cases each year, nearly one-sixth the total cases in postmenopausal for women. Obesity could be to blame for nearly 21,000 cases of endometrial cancer and more than 13,000 cases of colorectal cancer per year.
Researchers also said it was "Probable" that excess abdominal fat was a cause of breast cancer in postmenopausal women.
Experts took estimates of obesity's influence on cancer and applied them to to a breakdown of the approximately 1.6 million U.S. cancer cases per year.
Cancer is more often blamed on influences like smoking and often toxic exposures then it is blamed on obesity. Smoking does cause many more malignancies than excess body fat.
The group says overweight and obesity could be the cause of more than 6% of all the estimate 1.6 million cancer cases diagnosed in the U.S. each year.
