Information and help on the internet that I have found useful.
Warning : For the most part my tour of the net for information has been very positive but occasionally, and I stress occasionally, after effects of treatment and/or operations have been far worse than the person concerned had believed and this has led to extreme distress for that person. I have found this not to be the norm so please keep things in perspective if you go surfing the net.
Prostate Cancer Charity : Plenty of information here and I have downloaded some of their PDF pages to study at leisure. A good one.
