Tony,
There is hope for us geezers. Watch that PSA like a hawk. Did they give you a reason for the drop? Was it prostititus? My high PSA was only 7.3. You and your doctor need to be very aggressive with this thing. My doctor at the Mayo Clinic told me to congratulate my doctors at home for being so aggressive in the detection of my prostate cancer. Good luck my friend!
Tom
