前列腺癌
Prostate cancer is extremely rare in gonadectomized transgender women who have been treated with estrogens for a prolonged period of time. Whereas as many as 70% of men show prostate cancer by their 80s, only a handful of cases of prostate cancer in transgender women have been reported in the literature. As such, and in accordance with the fact that androgens are responsible for the development of prostate cancer, HRT appears to be highly protective against prostate cancer in transgender women.
