Propecia Alters PSA Results in Prostate Cancer Screenings?

Dear Doctor:

I saw this online about the cancer risk and PSA results of people on propecia. What do you think about this article?

Propecia and Prostate Cancer: Balancing Vanity With Health

Thanks for sending that link. It has been known for some time that finasteride will reduce the PSA levels so a pre-PSA level is critical to get, particularly if you are over 50 years old when you start the drug. Prostate cancer is highly unusual in men under the age of 50, so I routinely get a PSA test on all men over 50 who I start on Propecia/finasteride. The interesting studies indicate that this drug will reduce the risk of prostate cancer, and that is great news.
