How to lower weight and cancer risk
Why is there a link between obesity and cancer? "Excess fat tissue causes an overproduction of several blood and tissue factors that can initiate or promote growth of tumors, such as estrogens, testosterone, inflammation, insulin, and factors that cause growth of blood vessels that can feed tumors," said Dr. Anne McTiernan, a cancer prevention researcher at the Fred Hutchinson Cancer Research Center in Seattle, who was not involved in the new study.
"Both men and women have increased risks for several cancers if they are overweight or obese," she added.
