Well, we did mitomycin C first because I had a pretty rough time w/ the BCG.. I also had the mitomycin C wash as soon as my surgery was over with the grade 3 tumor..but then followed that with mitomycin. I have heard it helps a lot of people when BCG didn't work.. OR BCG with Interfuron.. about the same odds I think.
The BCG interfuron is a completely different set of side effects for me. Its not unbearable but I feel pretty yucky.
I would do what you could with treatments.. as long as the cancer isn't muscle invasive.
I wish you the best..
