I feel I should know the answer to this by now, but I'm a worrier. I had my RP in September 2018. Since then, I've had PSA readings every 6 months or so (last 2 were a month or two late). The PSA readings have NOT been ultra-sensitive; they have been under threshold--either <0.05 or <0.1.
Just got a reading of 0.1, and of course I'm jumping to conclusions. So what are the recommendations? Go for ultrasensitive test and follow? Go straight to the RO?
