Organised cancer screening in Korea began in 1999. Operating system has been stabilised, target population have expanded and participation rate has been increased throughout its ten years. Here we present an overview of the organised cancer screening system in Korea and introduce the National Cancer Screening Programme including results from 2002 to 2008. Furthermore, we present the results of the Korea National Cancer Screening Survey, a survey that is representative of the population, from 2004 to 2009. Finally, we discuss our achievements and the future challenges.
