BCG bacteria to treat Bladder Cancer | The Scientist

Bacillus Calmette-Guérin (BCG) is a puny cousin of the bacteria that causes tuberculosis, and as such serves as an excellent vaccine against the disease. But BCG is also used to treat bladder cancer. Research published today (June 5) in Science Translational Medicine reveals how BCG achieves its cancer-fighting performance, and suggests the bug has a better chance of winning if the patient has a prior BCG vaccination.
