Bacillus Calmette-Guérin immunotherapy

Bacillus Calmette-Guérin (BCG) immunotherapy is a treatment primarily used for bladder cancer. It involves introducing a weakened form of the bacteria that causes tuberculosis directly into the bladder. This stimulates the body's immune system to recognize and attack cancer cells in the bladder lining. The treatment usually requires multiple sessions and can help prevent cancer from returning or progressing. BCG is generally well-tolerated, with side effects often limited to mild urinary symptoms. It leverages the body's natural defenses to target cancer more effectively, offering a valuable option for patients with certain types of bladder cancer.
