was your PSA always up at the 15 level as in for years? In my own case, my PSA jumped from 2 to 8.5 and I figured my Gleason 6 was getting worse. The Mayo Clinic doctors said no, that jump was too big in one year and that it was probably prostatitis. They put me on antibiotics and retested me two months later and I was back down to under 2. So your jump could have been something like that unless you were always up at that level.. I will say a prayer all goes well for you.
