Cancer immunotherapy harnesses the body's immune system to fight cancer by developing antibodies or T cells that target and destroy cancer cells. Researchers are working to develop new immunotherapy approaches that use antibodies or T cells to identify and eliminate cancer cells while leaving normal cells unharmed. Immunotherapy holds promise as a revolutionary new approach for treating many cancer types by giving the body's own immune system tools to fight the disease.
