Hi Paul, they ablated about 2/3 to 3/4 or so, they took out a real lot. The goal was to take my formerly 110 cc prostate with some some small (one tiny) cancer spots into a 30 cc or so prostate with no cancer. The docs not worried if my former PSA of 16 bounces around like 3 or 4. That doesn't mean I love that it went up from 3 at 3 months to now 4. Anyway I have to wait so see if the work done has done the job and expect some PSA bouncing around is what I am told.
