benign prostatic hyperplasia
"I have been taking 0.5 mg of avodart twice a day for 4 years.  I have noticed no side effects and lab results verify that nearly all testosterone conversion to dihydrotestosterone (DHT) is blocked.  Since prostate cancer growth is stimulated by DHT, and not testosterone, my PSA has remained low (below 1)with no tumor regrowth (after radiation therapy)."
