Breast Cancer Incidence Reduction in Women Treated with Subcutaneous Testosterone: Testosterone Therapy and Breast Cancer Incidence Study

Key Points

•    In the United States, 240,000 women will develop breast cancer (BC) annually and 40,000 will die from the disease.

•    Testosterone hormone optimization has been shown to reduce the incidence of invasive breast cancer in women.

•    This study (The Testosterone Therapy and Breast Cancer Incidence Study) is the largest long term study to further demonstrate this benefit and shows a reduced incidence of IBC in women taking testosterone and estradiol sub-cutaneous hormone pellet therapy.
