Mark,
Sorry you qualified to join our club, but glad you found us.
Going to Sloan for your 2nd opinion is absolutely the right thing to be doing.
As Pat already mentioned (and you already said you are planning) you want to follow up on those slides and find out where there are and get your hands on them to bring to Dr. Dalbagni.
This diagnosis can be a scary thing no matter what your age.
Caught in early stages, bladder cancer is very treatable. It's going to be a pain in the butt for many years as BCG and regular surveillance are on the horizon. The good news is, that is very, very likely to be a looooooonnnnnnggggggg horizon.
We here call that a "Good Thing".
Since you've been lurking a few days and reading, you know we are very open to any and all questions. Keep us in the loop as you find out more and ask anything that comes to mind.
Mike
