Emcyt (estramustine phosphate sodium) is an oral medication proven to improve the quality of life (palliative care) of people with metastatic prostate cancer. In addition to directly damaging cancer cells, it lowers testosterone levels so they cannot grow or spread. Other medications treat prostate cancer better, so they aren’t commonly used.

Emcyt breaks down into two essential components when consumed: anti-cancer and estrogen. Estramustine breaks down into estrogens (estrone, estradiol) and cancer drugs (estramustine). According to research, this medication slows/stops cancer cell growth by increasing estrogens, which interfere with prostate cancer.
