Aug. 19, 2003 -- Obese women may be more likely to develop breast cancer largely because their bodies produce more estrogen than thin women do. New research suggests that the increase in breast cancer risk faced by obese postmenopausal women may largely be due to higher levels of estrogens circulating in their bodies.
Start exercising moderately. Exercise has been linked to a drop in estrogen levels. Avoid excessive exercising, but get regular exercise in. Not only is moderate exercise healthy, it may also decrease the risk of breast cancer in women and increase overall longevity. Athletes may experience a drop in estrogen levels.
