As Warren mentioned, the key is getting to major bladder cancer center with urologists that have extensive experience dealing with bladder cancer. They typically have multidisciplanary teams who evaluate your situation. These hospitals are typically teaching hospitals but not all are created equal.
Where are you located?
Did you have a severe reaction to the BCG? Typically, if BCG is given it is given once a week for 6 weeks and then followed up with maintenance doses (3 weeks every 3 months, then spread out over time).
Low grade is certainly the best to have if you have to have bladder cancer. Sometimes it is just treated with removal and then watchful waiting. Since you had more tumors within three months, it will probably warrant some additional treatment but a top urologist and a top bladder cancer center is really the one to make that assessment with you.
