Study: Active Women at Reduced Risk for Breast Cancer


Posted on May 14, 2008

A new study in the Journal of the National Cancer Institute has found that women who engage in regular physical activity are less likely to develop breast cancer than those who are not active.  This new study is one of the first to examine the impact of exercise on a woman's premenopausal risk of developing breast cancer.  Women whose weekly activity equaled 13 hours of walking or 3.25 hours of running had a 23% lower risk of developing breast cancer than those who were less active.

Several studies have examined the post-menopausal risk of breast cancer development.  The latest, published in the British Journal of Sports Medicine, found that physically active women have a rate of breast cancer that is 25% lower than that of those who aren't. 

While being fit in no way guarantees that you won't develop cancer, it does seem to reduce your risk.
