If you're into the science research on prostate cancer, I'd recommend watching the videos by Dr. Eugene Kwon at Mayo Clinic in Rochester. The videos are long, but, they're quite educational. I'm a little nerdy but I found these presentations extremely informative and helpful.

I too found the post-surgery pain to be considerably less than expected. In fact (IMO) the biopsy procedure was more distressing. I called it borderline barbaric ... but you survive.
