Dr. Paul Goss, the director of breast cancer research at Massachusetts General Hospital has revealed that they have found a new tool to prevent breast cancer. Tamoxifen, already a common breast cancer treatment drug is the cure. Patients need to take one of these pills daily, over a period of five years. Dr. Judy Garber, director of the Center for Cancer Risk and Prevention at Dana-Farber Cancer Institute stated that women taking Tamoxifen were half as likely to get breast cancer. At the moment, this treatment is only for women that have a high risk of breast cancer. This includes women who have had breast cancer before, have the BRCA gene mutation, have a family history or have had a biopsy showing changes in their breast tissue.
