There is a fairly high recurrence rate. Some types are worse than others. I suggest you ask your uro. DO NOT skip any cystos. You should be getting them every 3 months for a year, then every six months. Dr. Lamm is the doctor that has done the most BCG research. Look at his site for recommendations on maintenance doses. They are HIGHLY recommended. If you tolerate BCG without major problems then you should definately follow his protocol for maintenance doses. It can GREATLY reduce the chance for recurrence.

Another article on the protocol can be found here at the American Bladder Cancer Society wes site: http://blcwebcafe.org/content/view/112/122/lang,english/
Best of Luck to you!
