For what it is worth, get the second and third opinions, but do it quickly.
In my case, the post op pathology report stated the cancer "extends out to but not through the prostatic capsule". I believe if I would have waited very long, it may have penetrated the capsule.
I had only one of twleve biopsy cores show cancer and that one was only 10%. My PSA was only 3.4.
Good luck and best wishes.
