I'm not sure but I do not think you get as detailed an assessment of the variant after a biopsy as you do after an RP pathology. Happy to be corrected.
I would (based on bitter experience) get the hell off of Dr Google.
This forum would be a good place to get elaboration on any questions or for stuff that arises between consultations but your consultant should be the first port of call.
If you have questions going in to a consultation, write them down and write down the answers.
If you are worried you might miss something, bring your partner to act as scribe or ask to record the meeting.
Don't forget you can ring your onco nurse for advice and chats as well (also the PCUK hotline).
Keep on keeping on.
