Not to be nitpicky, but this doesn't make sense at all. A steroid does not have to be an estrogen antagonist (you meant antagonist right?) to be useful for breast cancer. It can block aromatase or simply impart strong anabolic/androgenic activity without estrogenicity, which helps block tissue growth by shifting the estrogen/androgen balance. It also doesn't have to be an SHBG blocker per say, nor does it need to be a DHT derivative.
