Mechanism of action

BCG works as an immunotherapy by activating innate and adaptive immune responses against tumor cells. When instilled directly into the bladder, it triggers local inflammation and recruits immune cells (T cells, macrophages, dendritic cells) that recognize and eliminate malignant urothelial cells. This mechanism has made BCG the gold standard for non-muscle-invasive bladder cancer treatment for decades.
