- A protein or other molecule that is found only on cancer cells and not on normal cells. Tumor-specific antigens can help the body make an immune response against cancer cells. They may be used as possible targets for targeted therapy or for immunotherapy to help boost the body’s immune system to kill more cancer cells. Tumor-specific antigens may also be used in laboratory tests to help diagnose some types of cancer.
