Certain products used in the bodybuilding community are sometimes vilified and labeled as unhealthy and dangerous. This is a big problem when the mainstream media gives false and misleading information about a product that has been proven to help people survive certain cancers and other ailments. Just one example of an anabolic steroid used to improve athletic performance and physique: Masteron (drostanolone) is an androgen and anabolic steroid (AAS)

The principal clinical indication of drostanolone in the United States as well as international markets was the treatment of advanced inoperable breast cancer in women.

Hormonal treatment is part of the complex therapy for some kind of tumors, particularly the ones associated with hormone-active tissues like breast or prostate cancer. Some types of breast cancer cells, expressing estrogen receptors (called ER+ cancers), use estrogen for their growth and dissemination. That is why drugs that block estrogen receptors or decrease their expression on the cell membrane, antiestrogens, could limit the tumor spread and size. Drostanolone (all esters) has been FDA approved as an antiestrogenic drug for the treatment of breast cancer. By the time of its release, there were not many alternatives for patients suffering from breast cancer and drostanolone was a revolution for these patients. As it has lower androgenic rate compared to testosterone, the risk of virilization is much lighter. Due to this fact, women, who usually do not respond well to any AAS, were having much greater chance to survive cancer. Drostanolone can also be used for breast tumors that do not respond well to other treatments or also as palliative care for advanced incurable tumors. The effects of the product depend of course on the dose and period of administration. The risk of virilization becomes greater with high doses and continuous administration period.
