If you havn't already done so, you need to obtain a print out of your biopsy report which provides details on the gleason score, % of cancer in each sample and a lot of additional information. The biopsy slides should be sent to an expert pathologist for a 2nd reading.
Biopsy readings are subjective: what looks like cancer to one person can look normal to another. It's surprising how many 2nd readings come back with a different diagnosis, which can sometimes influence consideration of treatment options.
Most important things is to find the best doctor available regardless of which treatment you select. There are a lot of variables like quality of the facility, equipment and treatment techniques, but a top doctor will provide the best chance of a good outcome with few side issues.
There are a lot of good publications available. For a very comprehensive and objective book, I like the one by Lee Nelson MD. Although written a few years ago, it covers the main treatment obtions, diagnosis, choosing your doctor, stages, lifestyle changes, diet,nutrition etc.
The book by Dr Scardino, who is one of the top surgeons, is also very informative, but would probably be more of interest where surgery is the main consideration.
The yananow site mentors section has stories from men who have used the various treatments, who would also be happy to provide answers to specific questions.
