title: Trends in Participation Rates for the National Cancer Screening Program in Korea, 2002-2012.
abstract: OBJECTIVE
  The National Cancer Screening Program (NCSP) in Korea supports cancer screening for stomach, liver, colorectal, breast, and cervical cancer. This study was conducted to assess trends in participation rates among Korean men and women invited to undergo screening via the NCSP as part of an effort to guide future implementation of the program in Korea.
  
  
  METHODS
  Data from the NCSP for 2002 to 2012 were used to calculate annual participation rates with 95% confidence intervals (CI) by sex, insurance status, and age group for stomach, liver, colorectal, breast, and cervical cancer screening.
  
  
  RESULTS
  In 2012, participation rates for stomach, liver, colorectal, breast, and cervical cancer screening were 47.3%, 25.0%, 39.5%, 51.9%, and 40.9%, respectively. The participation rates increased annually by 4.3% (95% CI, 4.0 to 4.6) for stomach cancer, 3.3% (95% CI, 2.5 to 4.1) for liver cancer, 4.1% (95% CI, 3.2 to 5.0) for colorectal cancer, 4.6% (95% CI, 4.1 to 5.0) for breast cancer, and 0.9% (95% CI, -0.7 to 2.5) for cervical cancer from 2002 to 2012.
  
  
  CONCLUSIONS
  Participant rates for the NCSP for the five above-mentioned cancers increased annually from 2002 to 2012.
