For Dad’s 50 not all that old, its good is sounds like the caught it early even if it turns out to be prostate cancer. Prostate cancer is very deadly in males especially, but normal very treatable if the catch it early. Its just that most guys are not to into a prostate exam so normal it progresses pretty far before the even catch it.

I truly hope everything will be ok with him, but does sound like the has regular check ups, and his Doc is on top of it, so more than likely even if it turns out to be prostate cancer he will be fine.
