It will be a year next month since I had my prostectemy. I’m 72. Gleason 9, extra scapular, etc. I just had my 4th PSA test and still < 0.01. Doctor is very encouraged. Will now get tested in 6 months. He made it clear that the two milestones are 5 years and 10 years. There certainly is a lot of mental anguish, knowing that the next test could be a red flag. I’ve made some dietary changes and continue to exercise(although I’m limited right now as I just had a total knee replacement). I’m enjoying every day. Try and be thankful you are undetectable. Enjoy each day. If and when there are changes in your health, take them on with the same determination you presently have. As I have learned, PC treatments have come a long way and it’s not necessarily a death sentence. I too, worry about the future, but have found enjoying the present has been better for my physical AND mental well being. Best wishes. Health and happiness. 🤞🙏🏻
