A new study finds women who gain weight throughout their adult life increase the chance they'll develop breast cancer after menopause.
Researchers at the National Cancer Institute found that when a five foot four woman gained 30 pounds between her 20s and 50s, her risk for breast cancer went up nearly 90 percent. Women who gained 30 pounds after age fifty had a 56 percent increased risk for breast cancer.
This is one of the largest studies on the link between weight gain and breast cancer -- over 72,000 women were included.
The study was presented at the American Association for Cancer Research conference.
