Hi, just finished SBRT about 6 weeks ago while doing ADT since February. I was 4+3 and cancer was pretty aggressive. My radiation was 5 sessions for the prostate and 3 for the hip bone. My PSA just prior to radiation was 0.19 and as of yesterday it was undetectable.
I've been on white button mushrooms for the past month and a half after reading clinical trial results from multiple places. I believe it helped to reduce my PSA and it looks like I'll be doing this maybe forever as long as my PSA remains where it is. I'm also taking CBD oil as there have been studies that it has a good effect on prostate cancer.
Good luck all. Dave
