Thoughts from my own experience:

1. When I got a 2nd opinion at the local center of excellence, they reviewed my biopsy slides and changed the one spot with 4+4 to 4+3. The surgeon I chose to do my procedure said that made him more willing to perform nerve-sparing if it were possible.

2. As a result, within 7 months of surgery, I had full return of continence and erectile function @ age 74.

3. Surgery after radiation is almost always more difficult/complicated with higher risk of damaging something due to scaring from radiation. That factored into my decision.
