Did you have ADT with your radiation treatments? If not, they say it may take 18+ months to reach target levels.

I had ADT with my 28 proton radiation treatments. 3 months after the first 3-month injection, my PSA was at 0.008; it stayed there for 6 months after the 2nd 3-month injection. Now 3 years later, it varies between 0.3-0.5.
