Breast Cancer and Testosterone

Evidence exists that androgens such as testosterone is breast protective and that testosterone therapy treats many symptoms of hormone deficiency in both pre-and postmenopausal patients. This study investigated the incidence of breast cancer in women presenting with symptoms of hormonal deficiency and imbalance that was treated with subcutaneous testosterone pellet implants compared to the natural historical control of breast cancer frequency incidence.

The natural history of the incidence of breast cancer in women who never took any hormones were studied in several very large studies indicates a natural incident between 300-400 cases of breast cancer per 100,000 person-years.

Testosterone delivered as a subcutaneous pellet implant reduced the natural incidence of breast cancer in pre-and postmenopausal women from the previously established average incidence of 350 cases per 100,000 persons-years to 73 cases per 100,000 person-years which revealed a significant reduction in the natural or expected incidence/risk of breast cancer in those treated with testosterone implants.

Rapid Response of Breast Cancer to a Combination of Testosterone-Anastrozole Therapy

This article outlines the response of a breast cancer tumor volume before and after the implantation of three testosterone implants with anastrozole were placed around a 2.4 cm breast cancer tumor followed by an additional three testosterone implants placed 48 days later. By day 46, there was a seven-fold or 700% reduction in the breast tumor size and volume. By week 13, there was a documented twelve-fold or 1200% reduction in breast cancer tumor volume!
