Can being overweight or obese cause breast cancer?
Excess pounds may predispose women to breast cancer because fat cells produce estrogen which may stimulate breast cancer. So although there seems to be no direct link between fat in the diet and breast cancer, being fat can predispose to breast cancer. The heaviest women in their 40’s and 50’s have twice the risk of developing breast cancer than the leanest women of the same age. However, there is no data concerning overweight and breast cancer recurrences.
