Biochemical rerrurrence after SRT
Had RP Jan 17. PSA undetectable for 1 year then reoccurred at .016. Tested 2 months later and at .028. Then underwent SRT and PSA was undetectable for 5 years. Now came back at .018. Tested 3 months later and now down to .008. Without a prostate why would I have any PSA number unless it was a reoccurrence and why would it go down on its own. Perplexing? Appreciate any clinical thoughts.
