OBJECTIVES: Organized, nationwide screening for breast cancer with mammography started in Hungary in January 2002. Women in the age group 45-65 years are the target population and 2 years screening interval is applied. The aim of this study is to analyze the attendance rate of the 3rd screening round (2006-2007). METHODS: The data derive from the financial database of the National Health Insurance Fund Administration (NHIFA) covering the period of 2006-2007. We calculated two attendance indicators. The up-take of the program means the percentage of women aged 45-65 who, having been sent an invitation for screening, attend a screening unit and undergo mammography in response to that invitation. We defined coverage as the ratio of women in the age group 45-65 years having either a screening mammography or a diagnostic mammography. RESULTS: In 2006-2007 there were 453142 screening mammography cases and 1248183 diagnostic mammography examinations in Hungary. We found 41.7 % and 52.5 % up-take in 2006 and 2007 respectively; and 46.3 % combined rate for 2006/2007. The screening coverage was 29.2 % and the diagnostic coverage was 21.6 %, while the total coverage (screening and diagnostic) was 49.3 %. CONCLUSIONS: The attendance of the Hungarian organized breast cancer screening program – compared to the previous period before the implementation of the organized screening program – is promising, although to achieve the expected results in mortality decrease a further improvement of both the uptake and coverage is necessary.
