Colorectal Cancer Screening
Although colorectal cancer is the third leading cause of cancer-related deaths in the United States, 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 50 years. However, the myriad screening options and slight differences in screening recommendations between guidelines may lead to confusion among patients and their primary care providers. In addition, varied colorectal cancer incidence and screening rates among different racial/ethnic groups, inconsistent screening recommendations based on family history and/or age, and increasing awareness of the role of nonadenomatous and nonpolypoid lesions also pose potential challenges to primary care providers when counseling patients. The goal of this review, therefore, is to briefly summarize the colorectal cancer screening guidelines issued by 3 major organizations, compare their recommendations, and address emerging issues in colorectal cancer screening.
