What is Male Breast Cancer?

Although breast cancer occurs far less frequently in men than women, the conditions exhibit similar characteristics in both sexes. The disease begins when normal breast cells grow uncontrollably, resulting in an unusual mass called a tumor. Tumors can be either benign (non-cancerous) or malignant (cancerous), in which case the tumor has the ability to metastasize and spread to other locations in the body. Breast cancer is seen less commonly in men because their breast duct cells are less developed than those of women, and because their breast cells are not constantly exposed to the growth-promoting effects of estrogen.

Propecia & Breast Cancer

The risk of developing male breast cancer may be increased in individuals who take Propecia over an extended period of time, according to the Journal of the National Cancer Institute:

Finasteride shrinks androgen-dependent prostate tissue by inhibiting steroid 5α-reductase, an enzyme that converts testosterone to dihydrotestosterone (DHT). However, inhibition of DHT production alters the estrogen-to-androgen ratio and may also increase the risk of gynecomastia and male breast cancer. Reports to the U.S. Food and Drug Administration (FDA) from June 1992 through February 1995 showed that gynecomastia had been observed in 214 men receiving finasteride therapy. Two of these men were subsequently found to have invasive ductal breast carcinoma. There was also a higher incidence of gynecomastia in men participating in the Prostate Cancer Prevention Trial. The rate of gynecomastia was 426 (4.5%) of 9423 subjects randomly assigned to the finasteride arm compared with 261 (2.8%) of 9457 subjects randomly assigned to the placebo arm. There was one case of breast cancer in each arm of the trial.

Propecia is a 1 millegram does of a drug used to prevent prostate cancer in men. The dosage for that purpose starts at 6 millegrams. At that dosage there is some greater side effects that include possible breast growth. Yes it is and anti-androgen but in the dosage to maintain hair it is at a too weak a dose to cause any feminizing effects
