Re making a fuss don't assume anything about the NHS is acting in your best interest, I am not talking about getting angry, start by making the consultants secretary your "best mate", stay informed (you are on here so that's a start!), Ask for your PSMA scan report, get your biopsy results in writing, make sure you are an informed patient.
Your negative PSMA scan is a good thing and much better news than the bone scans that used to be done.
You will know a lot more when they get your prostate on the slab, make sure you get the report!
