Brenda,
It is probably too soon to tell if your "wasting your time" with the BCG. BCG is very effective for CIS. CIS is highly agressive however it does require close monitoring.
Since you were Ta, it is still likely that BCG is the best course of action for now.
Can't tell you how pleased I am to read that you already went to MD Anderson for a second opinion. Now that you have the results of the cysto, you want to follow up back with Dr. Grossman and get his opinion.
I had CIS and mine came back after a couple of years. I had decided that I would get my bladder out if it came back because I wanted to be aggressive in treatment since it gave me the best chance of getting "cured".
Turned out that when it did come back it was already invasive (T2) so I didn't have to argue the point.
If this is a recurrence from your first TURBT only a few months ago, I wonder if they missed some or it seeded or if it's really a recurrence already. Not that it really matters though. Seems like it might be worth trying BCG as long as you can tolerate it as it does have a very high success rate, HOWEVER, Dr. Grossman should be the one to guide you on this one.
I'd suggest getting back in touch with him post haste. (If not today, then tomorrow).
