Many new and potent medicines to prevent breast cancer have become available in the past 20 years. Surprisingly, many women—even those at high risk for the disease—are not taking advantage of these medicines, according to an article in the January 2014 issue of the Harvard Women's Health Watch.
Drugs such as tamoxifen (Nolvadex), raloxifene (Evista), and exemestane (Aromasin) can reduce the odds of developing breast cancer for many women at high risk of developing breast cancer.
