Download the toolkit or phone the specialist nurses on the number at the top of the web page & ask them to send you a copy in the post. Read up on the treatments & make sure that you fully understand the implications of the different treatments - if you saw a urologist yesterday, ask to see an oncologist before you decide.
The men who cope best tend to be the ones who understood the potential side effects and were prepared just in case. The ones that struggle are the ones who either thought side effects wouldn't affect them (I am young, that probably only happens to old patients type thinking) or whose surgeon was over-confident and / or glossed over the negatives.
