Don’t forget that since you had radiation as primary treatment, you still have a healthy prostate remaining (though about 35% smaller than before).

Unlike those who had a prostatectomy - who have an expectation of undetectable PSA for the rest of their lives - your remaining prostate gland will continue to naturally produce PSA - though at “new normal” levels - for the rest of your life.

For you, a PSA of 0.(anything) ng/mL is good.

As for what to expect next? —> continue with regular PSA tests. If your PSA goes beyond 1.0 ng/mL, then start looking into it. (I’m 5-years post radiation; I have PSA tests every 6 months. My most recent PSA test was 0.314 ng/mL. See my attached PSA tracking chart.)
