Carol, bladder cancer as usually found is rather different from most other types of cancers, and so is its treatment. Unless there are metasteses elsewhere in the body, it is usually treated, as Pat said, by urologists with special training in the treatment of bladder cancer.
Again, to take note of Pat's comments, it is extremely important to find a urologist who treats a LOT of bladder cancer; most urololgists make their living treating prostate issues. And these bladder cancer specialists are most usually found in major universities and cancer centers.
Pat is the EXPERT on who is where in this field and, given your geographic location, can give you leads on many possibilities for treatment.
