Bomber, I assume you're getting periodic blood tests... especially PSA and testosterone. Hopefully that's reassuring.
Also, ask your oncologist if you're a good candidate for Lutecium-177.

I'm kinda of in the same situation and I feel like they have pretty much given up on me. My Urologist had me on ADT for about six weeks before he dropped me and my medication because I questioned his order for a transrectal biopsy. That was it no further discussion and he washed his hands of me. I'm 71 with a PSA of 287 and cancer in my bones and lymph and he still wanted me to undergo a biopsy without ever asking me how I felt about it. Pretty unethical if you ask me but I'm happy I didn't agree to a transrectal without a MRI. I'm in a rather rural area and far from a major city so even finding a Urologist is a problem let alone getting proper care. I probably should have expected such treatment from him when on our first and only visit he was wearing a mask. How can anyone have faith and trust in a health care professional when they won't give up the mask? It's like their badge of honor for their disgusting and inhumane behavior during the so called pandemic in which they acted like complete authoritarians. Power is an insatiable appetite that never finds content.
