[|Human|] I have Bladder Cancer and I had the Tumor removed 2/21/13. I had BCG treatments following the removal of the Tumor. It was supposed to be an outpatient surgery however it took much longer than it was supposed to because of the bleeding and cutting involved.  Today I had another Cystoscopy and he saw a growth that requires it to be removed again.  Why wouldnt a 2nd Cystoscopy be performed prior to the treatments to insure that all Cancer was removed visually at least prior to wasting 6 weeks of BCG treatment only to discover growth?  It makes no sense to me why one would assume everything was removed if it was that extensive.  Is it an ego thing that the doctor wouldnt consider looking to check his work to insure everything was good prior to jumping into BCG therapy?
[|AI|]  Hi and welcome to Chat Doctor. Thank you for the query. It is hard to say was it necessary to do cystoscopy. Because BCG is considered to strengthen immune response and prevent tumor recurrence. This is important even when there are no signs of tumor because there can be micrometastases or tumors which aren't visible. SO BCG would be helpful in such circumstances. All in all there is more benefit of BCG than cost. And it isn't so important to establish that there is tumor recurrence. Wish you good health. Regards
