I have been on testosterone injections for about ten years. Dr felt a bump and a biopsy found G 7 (3+4.) PSA 7.4, age 72. I was told to stop the injections until I saw the specialist and any treatment discussed. He said that as they treat people with normal levels, I could recommence the testosterone to get it back to normal, as long as it was monitored. The last reading was 10.6 and the normal range is 6 to 26. I had 60 Gy in 20 fractions which finished 1 March. So now waiting 3 months or so for the next PSA and testosterone tests. I hope I got all the terminology right. Happy days! Best wishes. Keep us informed.
