Factors Associated with Organized and Opportunistic Cancer

Cancer is the most common cause of death in Korea (Statistics Korea, 2011). In 2009, 69,780 people died of cancer, accounting for 28.3% of all deaths in Korea. That year, the incidence was 398.9 per 100,000 men and 376.9 per 100,000 women; it had increased rapidly from 1999 to 2009, growing annually by 3.3% (Jung et al., 2012). Because of the high incidence of cancer, the Korean National Cancer Center (KNCC) has been constantly expanding its organized cancer screening program (Park et al., 2012). The KNCC’s National Cancer Screening Program (NCSP) has been in operation since 1999 (Park et al., 2012). In the beginning, the NCSP for gastric (Lee et al., 2011), breast (Kang et al., 2013), and cervical (Jun et al., 2009) cancer was available only to Medical Aid
