Again, I don't know that I'd trust much of what you've told so far, but the one thing that is most baffling to me, is that if it is in-fact true, that there can be prostate cancer cells that do NOT have the PSMA surface protein (which I've not yet heard-of), then that would mean that a highly-specific and diagnostic prostate cancer imaging scan, like the PSMA-PET, would be utterly useless, since it would yield an 'untrue', false negative result. THAT, is what's scary to me! In fact, if true, it would seem to turn the whole equation of diagnosing and treating prostate cancer, upside-down. So second- and third-opinions, period! That's where I'd be heading, post-haste, and not from anyone at Mayo. Hopefully, that's what you're doing.

The very best of luck to you on this, and please keep us informed as you learn more.
