The study group consisted of a large group of , approximately 73,615 women who took part in a study begun by the American Cancer Society in 1992 called the CPS-II nutritional cohort study. During the seventeen year study 4,760 women were diagnosed with and the researchers specifically investigated status and levels of exercise.

The rate of decreased with the rate of exercise. The most active women had a 25% lower risk of .

“Our results clearly support an association between physical activity and postmenopausal , with more vigorous activity having a stronger effect,” said Alpa Patel, PhD, leader of the study and American Cancer Society strategic director of Cancer Prevention Study-3. “Our findings are particularly relevant, as people struggle with conflicting information about how much activity they need to stay healthy. Without any other recreational physical activities, walking on average of at least one hour per day was associated with a modestly lower risk of . More strenuous and longer activities lowered the risk even more.”

The findings were independent from weight and women also benefited whether or not they were taking menopausal hormone therapy. Exercise reduced the risk of both estrogen receptor positive and estrogen receptor negative cancers. (In estrogen receptor-positive , the female hormone estrogen promotes the growth of the cancer.
