Biomarkers Fact Sheet

Biomarkers (short for biological markers) are molecules found in body tissues and fluid, including tumor tissue and blood. In terms of cancer, biomarkers include vital information about your tumor. You may hear them described as “an expression of your tumor” or “your tumor type.” Typically, they are either a protein or antibody (molecule) released by a tumor, or they are a body’s response to the presence of cancer, which could show up like a gene mutation.

Knowing your biomarkers can help your doctors identify your best treatment options and help you in making well-informed decisions about how your cancer will be treated. Knowing your biomarkers will allow you to be your own best advocate.
