Sorry that I misread your .041 as .41. It is definitely low at this point. You have a while before it even reaches .2 if it does. At least now you know what the options are for getting treated.

When my PSA hit .2 after a prostatectomy, I was given a Lupon shot and two months later had salvage radiation. That’s sort of the ideal treatment, They didn’t have PSMA PET scans back then. Today you can have a scan and see if something shows up that can be zapped before SRT.
