Educate yourself - it's amazing how much peace of mind it brings. Stick around here and read books.
My doc told me that 40% of men my age (47) were walking around with my level of PCa and had no idea. His message - don't panic. Sounds like yours is early and non aggressive. Weigh your options, get a second opinion and go from there. BTW - opinions i found did not vary much at all. They all agreed I could do watchful waiting, but eventually would need surgery because of my age. I talked to four excellent uro's. You will likely find similar consensus re: your first uro suggested.
