@jeffmarc Thank you so much for this useful information. Because my cancer is already known to be aggressive, my urologist said the genetic test isn't useful. Obviously, with surgery, they will analyze the cancer after the fact - another up vote for the surgical option. All of this is really helpful.

I remain inclined towards surgery - not least because my surgeon is one of the best in the country and essentially said "I can take care of this" with an informed confidence that was reassuring. I fully expect recurrence and that it will be a chronic issue for the rest of my (hopefully very long) life.

Glad to know you're doing so well. Thank you again for sharing.
