Gaining, Losing Weight at Menopause Affects Breast Cancer Risk
New information from the Nurses Health Study indicates that women who gain
weight before menopause may have an increased risk of breast cancer, while women
who lose weight after menopause may decrease their risk.
The research looked at 87,000 women for 26 years, examining weight changes
and incidence of breast cancer. Results showed that women who gained 55 pounds
or more after age 18 had nearly 1 ½ times the risk of breast cancer compared
with women who kept their weight steady. Women who gained 22 pounds after menopause
had an 18 percent increase in cancer. But losing 22 pounds after menopause decreased
the risk by 57 percent.
