Screening is the process of looking for cancer in people who have no symptoms of the disease. Current colorectal screening options are described through the links below. These tests can be divided into: 1) those that can find both polyps and cancer, and 2) those that mainly find cancer.

Screening for Polyps and Cancer These tests look at the structure of the colon to find any abnormal areas either with a scope inserted into the rectum or with special medical imaging (x-ray) tests. Polyps found before they become cancerous can be removed, so these tests may prevent colorectal cancer. Because of this, these tests are preferred.
Screening to Find Cancer These involve testing the stool (feces) for signs that cancer may be present. These tests are less invasive and easier to have done, but they are less likely to detect polyps.
