I imagine you feel gutted. Mine never went to undetectable after RP with a low of .03. BCR after 2 years with doubling every 6 months second year, followed by radiation and ADT which I am finishing up in 4 days. Best of luck and hope you are going to a research hospital instead of a private practice. One uses standard of care which translates to safe for the doctor and the other cutting edge with SOC and stage 3 drug trials looking a cure. I'm surprised they aren't proposing a PSMA and suggesting ADT and radiation. .2 was my providers trigger point. Research hospital Genitourinary doc suggested waiting until 2.0 and stated they could find it and treat it at that point. That will gin up some controversy in the room. Best wishes for you with these challenging decisions that you have to make.
