I've getting checked for quite awhile, same urologist. He noticed a spike in my PSA and did a biopsy("you'll feel a little pinch".

Yeah, right! That's why they have you face the wall). Everything fine. Next PSA , good numbers . A year or so later, another spike, another biopsy. Again, AOK. Coupla low numbers then another spike. He asked some questions, I answered. Turns out someone shouldn't have assumed that I knew to refrain from 'activity' for 36 hours +/- before the blood draw

. It would've been a useful bit of information to have. Numbers have all been good since then.
