What is BCG (Bacillus Calmette-Guerin) treatment for non-muscle invasive bladder cancer?

BCG (bacillus Calmette-Guerin) is an intravesical immunotherapy using a bacteria of Mycobacterium bovis (bovine TB) that has been reduced to cause less harm to the body. The bacteria is still kept viable (or "live") so that it can actively work in the body to kill the cancer cells.

Intravesical is a way in which a medication is put into the bladder. Liquid drugs are put directly into the bladder through a catheter.

BCG is used as a therapy for and protection against bladder cancers that come back after a period of time in patients that have a more aggressive bladder cancer diagnosis. It is currently the most effective treatment.
