I've been stage IV since (200😎. PSA is .265 been clmbing for a while now. Third relapse after RP. NED other than PSA. I'm curious if there is any way to locate the tumor at my level. Doc said I could go to Mayo and spend $10K of my money-but no point since treatment would be the same with PSA results. Thinks its in my spine 99% chance. Any good things out there to locate-heard of a new improved PSA-PSMA maybe. But I do annual bone scan and xrays are always negative. Doc says 7.0 ng PSA level to see on scan. Thanks
