[Evidence-based colorectal cancer screening]

Colorectal cancer has been identified as an appropriate candidate for early detection and treatment of both asymptomatic individuals and those at risk of the disease. The lifetime incidence of colorectal cancer among persons at average risk is sufficiently high to justify screening the general population. This review presents the latest strategies employed in early detection of the colorectal cancer. An ideal screening test should satisfy some basic criteria: must be simple, secure, accepted by the population with valid and reproductive results. Despite the demonstrated benefits of colorectal cancer screening, incidence and mortality rates of this common cancer remain high. More optimally tailored screening tools are needed that combine the features of a potentially ideal screening test.
