From what I'm reading, your story is as of yet, incomplete. Correct me if I'm wrong. You say there is a diagnosis of bladder cancer from a cysto. Cysto's find tumors, not necessarily cancer. Your next Cancer Center visit will be for a surgery? (TURBT). This is to remove what they found (the first attempt), from which the tumors(s) will be analyzed for a pathology report to determine what it is, and what stage (more waiting). Now you have more specific information for her, and can determine how to proceed. Glad you found this place.
Chasing B-C via online sources will generate undue fear and anxiety. Best wishes for both of you at this time.
