You've gotten good information and thorough answers to your questions.
Only thing I'd add, is that it's not unusual for a Uro to always plan on giving the results face to face. The Uro I went to, told me on the day if the biopsy, that I should make an appointment to come back, as his protocol is to have an I. Person discussion on the results whether positive or negative. (My results were negative for cancer, first biopsy). In fact my second biopsy, with a different Uro, and it was positive for cancer, and I was told over the phone , 3 days after the procedure.
So While I don't want to give you false hope, don't jump to conclusions that might lead you down a black hole of fear and panic. Keep your imagination in check.
