Colorectal Cancer Screenings

Screening is the process of looking for cancer in people who have no symptoms. Several tests can be used to screen for colorectal cancer (see American Cancer Society Guideline for Colorectal Cancer Screening).
People at an increased risk of getting colorectal cancer should talk to their doctor about when to begin screening, which test is right for them, and how often to get tested. Several screening tests can be used to find polyps or colorectal cancer.
Different modalities are available ranging from stool based tests to radiology and endoscopy with varying sensitivity and specificity. However, the availability of these tests is limited to areas with high economic resources. Recently, FDA approved a blood-based test (Epi procolon®) for CRC screening.
