I'm 82 years old and did an MRI, Biopsy and PET Scan with very minor inconveniences. I'm now being treated for metastatic prostate cancer by two means. They are Camcevi 42 mg subcutaneously every 6 months and Xtandi four 40mg pills taken daily. This is not a cure, but the treatment is very tolerable, and I feel good about my life being prolonged.
