Did I have all this treatment, and all these negative results for nothing? I’m 69 and was diagnosed with prostate cancer after a physical exam, scans, including nuclear bone scans and a prostate biopsy. At the time my PSA was 6.0 and my Gleason score was 7. I elected proton radiation and underwent 30 session of beam radiation. Following that I had 18 months of ADT. My PSA is now 0.15 and I have no testosterone, no libido and can’t remember my last erection. I read about individuals with PSA readings in the hundreds. I wondering why I put myself through all this.
