Re: Should I repeat a bioposy?
The "rare atypical small acinar proliferation" means they couldn't get a good read on what it is - often it is cancer, often not. It's a strong indicator of a do-over. You don't know the Gleason scores of the missed cores either -- it could change everything.
If the biopsy was painful, you can ask for a nerve block. It's painless and doesn't leave you drowsy like anaesthesia does. I'd wait until I recovered from the last test, though, and make sure you get antibiotics before and after -- lots of bacteria in there.
