As Alan noted, your description of the diagnosis is a little confusing. You should ask for, and receive, a copy of the pathology report for your information and for your records. IF the tumor is high grade and IF it has not progressed beyond the bladder lining BCG is the standard of care. There has been a shortage of BCG in the past few years but I understand that this situation is now much better. Depending upon when your TURB was a month would not be an unusual time to wait since if takes about that length of time for the bladder to heal from the procedure before BCG can be administered. However you wouldn't want to wait much longer.
A second opinion might be a very good idea in your case. You would want to request it from a place that treats a LOT of bladder cancer patients such as a university medical school urology department or a National Cancer Institute designated cancer center. IF your cancer is invasive, BCG is not the treatment most urologists would recommend.
