A new study finds that regular physical activity may delay drastic preventative measures, such as a mastectomy, among women at high risk for breast cancer. The study involved 139 premenopausal women who were at high-risk for breast cancer due to either genetic mutations or family history. They were divided into three exercises groups: a “low-dose” group that performed 150 minutes of treadmill exercise per week, a “high-dose” group that exercised 300 minutes a week, and a control group that exercised for less than 75 minutes per week. After five months, the control group showed a 20% increase in estrogen-sensitive breast tissue, while the low- and high-dose groups saw reductions of estrogen-sensitive breast tissue of about 8% and 12%, respectively. The authors suggest that women who have an elevated breast cancer risk should consider performing 30 to 60 minutes of aerobic activity per day, five days per week.
