Prostate Cancer Foundation pcf.org has free Patient Guides that can be downloaded or requested in hard copy.
Patrick Walsh MD's book Surviving Prostate Cancer is a resource appreciated by many on this site including me.
You may be asked many questions by men on this forum including your age, PSA results, number of Biopsy samples taken each time and general health.
Surgery or radiation are the primary treatment choices.
At 72, I had surgery for Gleason 9, and would choose surgery again.
Hopefully your 2d opinion will provide insightful information.
I understand the whirlwind urgency; I had RP 4 wks after biopsy.
Best wishes.
