That was good news, indeed! The "usual" protocol followed in cases such as your husband's is to have a cystoscopy exam every three months for about two years, then every 6 months until about 5 years have passed, then annually forever. The only "bad news" about your husband's diagnosis is that this type of cancer can come back, which is why the vigilance of the frequent exams is important. IF it does return, it will be found early and removed.
No, BCG is not used in cases such as his. Since the cancer was removed, there is nothing currently there to treat. Also, it is not as effective in low-grade bladder cancer as it is in high-grade. It does have side effects, which are cumulative, so it is best saved for times when the patient really needs it. IF low grade bladder cancer returns multiple times BCG is then a possibility.
