State of the Art Review: Colorectal Cancer Screening

Although colorectal cancer is the third leading cause of cancer-related deaths in the U.S., the burden of this disease could be dramatically reduced by increased utilization of screening. Evidence-based recommendations and guidelines from national societies recommend screening all average risk adults starting at age fifty. However, the myriad of screening options and slight differences in screening recommendations between guidelines may lead to confusion among patients and their primary care providers. This goal of this review is to briefly summarize the colorectal cancer screening guidelines issued by three major organizations, compare their recommendations, and address emerging issues in colorectal cancer screening.
