Background: The EDIFICE survey aimed to investigate the compliance of the general population to the screening tests available in France for the 4 most common cancers: breast, colorectal, prostate and lung. Implementation of breast cancer screening has been generalized in France since 2003: women aged between 50 and 74 years are systematically invited to perform a mammography every second year. Results pertaining to breast cancer are reported hereafter.
Methods: This nationwide observational survey was carried out in France from 18 January to 2 February 2005 among representative samples of 773 women aged between 40 and 75 years and 600 general practitioners (GPs). Information collected included socio-demographic characteristics, attitude towards cancer screening and actual experience of cancer screening, as well as GPs' practice regarding screening. The precision of the results is ± 4.3% for a 95% confidence interval.
Results: Among the 507 participating women aged between 50 and 74 years, 92.5% (469/507) had undergone at least one mammography: 54.6% (256/469) underwent this test on their own initiative and 44.6% (209/469) of women performed it in the framework of a systematic screening plan. Most women participating in the systematic screening (89.0% i.e. 186/209) had a mammography within the last dating from less than 2 years versus 73.8% (189/256) of those who performed it outside the screening program (Chi2 test; p<0.01). Interestingly, 422 women (61.9% i.e. 422/682 women aged between 40-75 years with at least one mammography) had performed a mammography before the recommended age for screening. There was a significant correlation (p = 0.009) between the existence of a first mammography before 50 years of age and subsequent screening on women's own initiative (54.6% of 469 screened women). Main reasons for not performing the screening test every second year (77 women aged between 50-74 years) included: feeling unconcerned and/or unmotivated (p = 0.0001), no cancer anxiety (p = 0.020) and no recommendation by the GP (p = 0.015); Of the 600 participating GPs, 68.6% (412/600) systematically recommended a mammography to their patients. GPs' perceptions of the reasons for women's avoidance of the screening test were unwillingness to be aware of mammography results (44.4% - 266/600) and the belief that mammography was painful (52.5% - 315/600).
Conclusion: The main result of the EDIFICE survey is the high rate of women's attendance at mammography screening. The EDIFICE survey pointed out that systematic and organized screening played a major role in the regularity of screening tests for breast cancer every second year. GPs and gynaecologist are key actors in heightening public awareness.
