VancoverIslandHiker, Boy sounds like you live in a great area and beautiful. Live in Florida so if you don't (I do though) like the ocean not much else here.

Forgive my lack of knowledge but the undetectable PSA level is something like .02 (again I am not sure but there is a bottom number) what that number means is undetectable not that PSA was found.

If you had your prostrate removed it should be at that undetectable level as told to me by my PCP and urologist. If the PSA starts going up it is not something generated by your prostate which again could be normal and not be caused by cancer. If you numbers go up an indicator that the prostrate cancer had spread to another area and is generating PSA again.

I read one post that said something about other causes of having some PSA but I am not familiar with that information. I heard the same thing from my Urologist that I was not going to die from prostrate cancer but it was based on the type I had, within my prostrate only, and my tests scores. His father died of prostrate cancer.
Merry Christmas to also James and hope you new year is a good one.

I am going to forget 2023 as was diagnosed back in January/February and almost the entire year has been dealing with the anxiety over prostrate diagnosis, testing, treatments, and now my first two follow testing after treatments.
