Efficacia preventiva dei programmi di screening in Europa

"After considering all published data from European studies, the reduction in breast cancer mortality associated with mammographic population-based service screening programmes is in the range of 25–31% for women invited for screening and 38–48% for women actually screened with  sufficient follow-up time. It appears that much of the current controversy surrounding the value of mammography screening is due to the use of inappropriate methodological approaches that are unable to capture the true effect of mammographic screening. Overall, the results of this first comprehensive review of European breast screening services show that for every 1,000 women screened every two years from the age of 50 to the age of about 68-69, between seven and nine lives would be saved, and four cases would be over-diagnosed. The European breast screening programmes are preventing large numbers of breast cancer deaths, and the benefits outweigh the harms of screening. The programmes should continue to provide high quality screening services and should work towards achieving targets on coverage, uptake and assessment rates. In addition, communication methods should be improved in order to raise women’s awareness, and to make information on the pros and cons of breast cancer screening more accessible, relevant and comprehensible"
