PSA is less than 0.1 today yet again, nearly 16 years since I finished salvage radiation.

Since it seemed to be creeping up on ultrasensitive tests in 2020 and 2021, I started seeing an oncologist that specializes in prostate cancer. But it really doesn't look like anything--probably a protein that's close enough to PSA to trigger a response on the ultrasensitive test. 

So we're going to go to checks every 6 months, vs. every 4, and then I imagine I'll just go back to yearly checks.
