I had 20 treatments 3 years ago. The treatments are pain free and last less than a minute. The only side effect was some pain while urination that started a week in. Flomax drug took care of pain but needed to continue using it because radiation can have lasting effect on muscles in urethra. I have 6 month check ups and PSA has been negligible every time. Other then the commitment to the time for treatments, the side effects are much better then friends who chose surgery. You will likely meet other men going through the same experience. The group experience helps make it through it.

Best of luck.
