It sounds like all this “let’s wait and see” advice is coming from your befuddled surgeon, right? Politics and bruised egos aside, you should be seen by a Radiation or Medical Oncologist Immediately to start ADT in my opinion as a layman.
Surgeons like to wait snd see since they don’t want their surgeries to be viewed as “failures” right off the bat. But with your aggressive G9 and a type of cancer that doesn’t really express a lot of PSA, by the time you reach the .2 level it might be too late.
I met a man whose PSA was 1.0 and he had a highly aggressive G10. So YES, you can go on ADT now and it will stop your cancer spread while you heal from the surgery. You DO have to heal for about 90 days before starting radiation but ADT is sometimes even started before surgery if a cancer is aggressive enough. I agree with you that you are wasting valuable time and should act rather than wait.
