I believe that BCG is the treatment of choice when the tumors keep returning. It isn't really fun, but is not usually that bad either (how is that for damning with faint praise?) I, and lots of others in this group, have been through this and are, at least as of now, cancer-free.
Very good idea to make a list of questions and schedule a time to discuss these, calmly, with your uro.
There is a lot of info on BCG on this web site, and we are all willing to offer answers to questions.
