The incidence of colorectal cancer is rising and increasing public awareness of this condition has stimulatedinterest in screening tests. Colorectal cancer is treatable and curable in its early stages and clear benefits arepresent if the cancer can be detected in its early stages. Sensitivity of the faecal occult blood test (FOBT) byimmunochemical techniques for colorectal (CRC) cancer screening has been reported as 67% to 89% in certainpopulation screening programs. Although much work has been done to address screening of colorectal cancer inthe community, not much has been done to establish what the expected outcomes of screening are in a cohort ofvoluntary asymptomatic individuals. This paper retrospectively reviews the findings in such a cohort whosought health assessment (including a FOBT) at a Health Screening Centre in a tertiary hospital in Singaporeover the period of 2002 to 2007. The outcomes are discussed together with references to other relevant studies onfaecal occult blood test screening of CRC.
