This PDQ cancer information summary for health professionals provides comprehensive, peer-reviewed, evidence-based information about colorectal cancer (CRC) screening. This summary is reviewed regularly and updated as necessary by the PDQ Screening and Prevention Editorial Board ¹.

Information about the following is included in this summary:

• CRC incidence and mortality statistics and information about CRC risk factors.
• CRC screening modalities.
• Benefits and harms of CRC screening.

This summary is intended as a resource to inform clinicians and other health professionals about currently available CRC screening modalities. The PDQ Screening and Prevention Editorial Board uses a formal evidence ranking system ² in reporting the evidence of benefit and potential harms associated with each screening modality. It does not provide formal guidelines or recommendations for making health care decisions. Information in this summary should not be used as a basis for reimbursement determinations.

This summary is also available in a patient version ³, which is written in less technical language.
