When I went to Mayo/Rochester for biopsy (11/2019) I was aware of laser ablation. I found out that Mayo wasn't, at that time, doing laser ablation, but was doing cryo ablation experimentally. I had an anterior tumor in my prostate (Gleason score 4+3). I was approved by Mayo for cryo ablation, but when I asked about reoccurrences I believe the answer was 25% in two years time. For me (age 70 at the time) that was too high a number and too soon. I rolled to Proton Beam Treatment, which I had five treatments in early February 2020, with a short course of ADT (4 months). So far my PSA is staying around .02.
