In Poland, there is a breast cancer screening program addressed to women aged 50–69 who meet one of the following criteria: (1) have not had a mammogram in the last two years, (2) have received a written indication to re-mammography after 12 months (within the breast cancer prevention program), due to the burden of the following risk factors (breast cancer among family members (mother, sister, daughter); mutation in the BRCA1 or BRCA2 genes; no previous malignant breast cancer). Here, BRCA1 is linked to breast carcinoma.
