The study is a prospective interventional cohort study conducted within the Slovenian national breast cancer screening programme DORA at the Institute of Oncology Ljubljana.
Women aged 45-49 years and 70-74 years will be selected from the Central Population Register and invited by mail to participate in screening mammography. Screening and any required additional diagnostic assessment will be performed according to the established procedures and quality standards of the DORA programme.
The primary objective is to evaluate key breast cancer screening quality indicators in the two age groups, including participation in screening and the proportion of screened women referred for additional assessment. The study will also collect information relevant to the development of age-specific communication strategies and to the planning of personnel, equipment, information systems, and infrastructure required for a possible expansion of the national screening programme to women aged 45-74 years.
The planned sample size is approximately 2,150 women.
