A biomarker is a piece of information about your health. Biomarkers include your blood pressure, your blood type, and cholesterol or blood sugar levels measured in a blood test. The biomarkers of cancer are also known as tumor markers.
Patients and survivors are sharing their stories about colorectal cancer and biomarker testing.
Colorectal cancer patients would like to hear from you about your experience with biomarker testing, what you learned from your results, and how it affected your treatment. Help us encourage all CRC patients to know their biomarker.

Knowing your biomarker can connect you with clinical trials treating cancer just like yours. New targeted therapies are being developed, and you may benefit from participating in a clinical trial. Learn more about clinical trials and how they fit into your cancer care.
