You should be able to call the department and ask for a chat with the prostate clinical nurse specialist (CNS) - may be a Macmillan nurse. They are very good at explaining things and will have more time than the consultants, and you can probably see them within days (or even same day - I have popped in without an appointment a couple of times).
Unfortunately (particularly outside of England), many hospitals don't have CNS, and even in England, numbers are dropping with vacancies unfilled. (I read a report showing 50% of CNS are due to retire during next 10 years, just at the time when their workload is increasing fastest.)
