Since 2006, under the National Programme to Fight Cancer Diseases (NPZCHN), programs to prevent breast and cervix cancers have been implemented. But their impact on incidence of and mortality from the cancers, as well as on the numbers of survivals, is not significant. The aim of the social auditing was to evaluate the effectiveness of the programs after 10 years of implementation of NPZCHN and to develop conclusions and recommendations for necessary changes in implementation of the programs in the next 10 years. During the auditing activities, meetings with representatives of 20 public institutions deciding on the cancer prevention methods, experts and MPs were held. 33 deepened interviews were conducted among stake-holders and experts on the implementation of the National Programme for Preventing and Early Diagnosing Cancer, as well as questionnaire surveys among 1051 women (including 150 from single mother homes) and 50 deepened phone interviews. Each of the three stages of the auditing were summed up in a report, and the whole work was presented in the final report containing the main conclusions from the analyses and surveys led, the diagnosis of the problem of low reporting and ineffectiveness of screening programs, and recommendations for the ministry of health that can improve the effectiveness of screenings in the next 10 year of implementation. The recommendations concerned both professional and organisational, managerial, administrative, financial and communication aspects of the programs. A conference to sum up the project was also organised where the results of the auditing were presented to over 60 participants, including representatives of institutions that are crucial for cancer prevention: MZ, NFZ, COK, NIK, PZH, media and patient organisations. The report was publicised in media where it was cited 290 times. The project will benefit women reporting for preventive screenings for breast and cervix cancers who will be helped by better implementation of the programmes. The cooperation with Icelandic and domestic partners had a professional nature and consisted mainly in supplying materials for the report, participation in meetings with decision-makers, and joint presentation of the results of the auditing during the conference.
