Although my rad oncologist did not need me to get a PSA test until 3 months after SRT was complete, my uro surgeon wanted me to keep getting monthly PSA tests for now. My Sept 8 test result, which was at 5 weeks thru SRT, was 0.17, down from 0.41 the month before. I just called to confirm that this was not an error.
I was prepared to wait many months to see a drop, and had been warned it could be 3-6 months before I would see one. Has anyone else seen a drop this early on? I am trying to figure out whether the PSA fell for unknown reasons, or whether the radiation can actually be blamed for the drop.
Now I ain't complaining... in fact, I'll take it!
