Cancer immunotherapy uses the immune system to help fight cancer

  • The immune system is the body’s natural defense against infection and disease, including cancer.

  • T cells are a type of white blood cell and an important part of the immune system. They can find, target, and potentially eliminate harmful cancer cells and foreign invaders in the body.

  • Immunotherapy has the potential to work with the immune system to fight cancer. Immunotherapy most often looks for certain targets, which may appear on both cancer and healthy cells.

In the last few years, the Food and Drug Administration (FDA) has approved some CAR T cell therapies for certain types of blood cancer. However, some are still being studied in clinical trials.
