Nancy,
I am not an expert on terminology -- TCC (transiitional cell carcinoma) is the common term applied to most bladder cancer and that's what I was originally dx as having, although I had both papillary and CIS tumors, and even after 6 rounds of BCG they recurred after only about 6 month. Good news was that everything so far has been noninvasive and that's the main thing. You can learn a lot on this forum from those who have been posting for years, like Patricia, Rosemary, Wendy, Rosie, Zack and so many others too numerous to name. Dr. Lamm is also a great resource and he will answer your e-mails if you have a question. Back when I was having a lot of inflammation from BCG, I asked Dr. Lamm if that was normal and he responded right away. I shared this e-mail with my urologist and since then he has treated me with a lot more respect as someone who has taken an interest in his own treatment. I don't know if this approach would work with all doctors but in my case it certainly helped.
