How Can You Prevent Breast Cancer?
Studies have shown that limiting alcohol, engaging in regular physical activity, consuming more fruits and vegetables, avoiding smoking, and limiting night shift work may reduce your odds of breast cancer. Mastectomies (the removal of one or both the breasts) and the therapeutic use of the drugs raloxifene and tamoxifen can also help prevent breast cancer.
