Because the cancer was outside the prostate, as well, I was told that radiation was my only option along with ADT which I was in for 18 months. No metastasis to bones yet, but to seminal vesicles and pelvic areas. Progession now after docetaxal, Zytiga, Casodex. Still on Lupron. Waiting to see who is going to biopsy as tumors are hard to reach. Docs aren't sure what the growing tumors are, prostate or lung which was diagnosed in both lungs last year. So far nothing has worked for me. I still have Lynparza to try as a last option.
