Immunotherapy is a type of biological therapy which boosts the body’s immune system to fight cancer.

Immunotherapy strengthens the immune response and prevents cancer cells from evading detection by the immune system. Rather than directly targeting cancer cells, immunotherapy works by training the immune system to selectively attack and destroy cancer cells. This can involve suppressing factors that inhibit the immune response or enhancing the immune system’s ability to recognize and target cancer cells.

The main types of immunotherapy drugs being studied for lung cancer include immune checkpoint inhibitors, therapeutic cancer vaccines, and adoptive T cell transfer. Currently, immune checkpoint inhibitors have shown the most progress and are the approved immunotherapy drugs for lung cancer.
