Regular physical activity could play a role in helping women at high-risk of breast cancer delay the need for drastic preventive measures such as prophylactic mastectomy, according to new research led by the Perelman School of Medicine at the University of Pennsylvania. Results of the WISER Sister study help clarify the emerging connection between exercise and breast cancer risk. As a result of the new findings, the authors suggest that women who have an elevated breast cancer risk or worry about having such risk should consider doing 30 to 60 minutes of aerobic activity per day for five days per week. The results are available today in Breast Cancer Research and Treatment.
