Biomarker testing provides more information about cancer— beyond the type and stage. A biomarker is a molecule in the body that doctors can measure to tell them something specific about the person and the cancer. Health care providers who test for biomarkers are trying to find out if the person has a cancer subtype that matches to a targeted therapy drug. Watch this 5-minute guide from our Precision Medicine video series to learn more about biomarker testing and how it is being used to diagnose and treat cancer patients.
