It makes no sense to use BCG if you don't have cancer. BCG is actually most effective on CIS (an aggressive surface layer form of bladder cancer). If you tumors were not cancerous you should say yipee!!!
Consider yourself pretty darn lucky even if you do have more non-cancerous tumors come back.
It can be a nuisance getting scoped. Will they keep coming back? Maybe. A lot depends on what they are. As Catherine said, get your pathology report to see what it says. Talk to the doctor (whichever one you see) with the pathology report in your hand. Ask him/her if they are going to just keep coming back and what the risk is for actual cancer.
Congratulations on not having cancer!
