Overview

Colorectal cancer genetic testing can tell you if you carry rare changed, or mutated, genes that can cause colorectal cancer. Although most people who get colorectal cancer do not have one of these mutated genes, having certain gene changes can increase your chance of getting colorectal cancer.

The most common genetic changes related to colorectal cancer are familial adenomatous polyposis (FAP) and Lynch syndrome. In these conditions, screening often starts sooner than age 40.

Your doctor may suggest genetic testing if your family history or your personal medical history puts you at an increased risk for colorectal cancer. If you have an increased risk, your doctor may also recommend you start cancer screening earlier than someone who has an average risk of cancer.
