Yes, I'm out of my depth here too, but I'd think that once you've had confirmed prostate cancer — even if it's considered cured now — genetic markers showing that you're more likely to develop prostate cancer no longer add any value to refining the PSA result. You know you can develop prostate cancer because you *have* developed prostate cancer, so your oncologist already knows to take your PSA result seriously.

Again, I might be misunderstanding.
