So you had a biopsy in 2015 that showed Gleason 6 cancer?
I'm just going to give you my opinion okay. I'm not a doctor but my husband had prostate cancer, Gleason 7, at age 56. He had a prostatectomy. The reason we did this versus radiation, HIFU, or cryo therapy is because these can all cause problems down the line. Who wants bladder cancer 10 years down the road because he did radiation. Now this is not a given but something to think about. So I see you are 63 and I'm thinking you have more than 10 years left to live and so who wants to watch cancer grow? How often are they recommending biopsies? My husband had Gleason 7 with a PSA of 3. I believe what you don't want to see is the up and down of the PSA levels. They should be zero actually. I cannot tell you anything about the testosterone treatment and how it would affect your PSA level. What does your doctor say?
