Abstract

Introduction: Service mammography has been offered biennially to women aged 50-69 years in the municipality of Copenhagen since 1991. The results were compared to breast cancer cases before initiation of screening. The comparison concerns prognostic factors and the treatment-related consequences. Material and Methods: Data from the Copenhagen service mammography screening were linked to data from the DBCG database. Results: Before screening, 16% of breast cancer cases had a tumour size of 10 mm or less, this percentage increased to 41 in the screen detected cases. Sixty per cent of breast cancer cases showed no evidence of metastatic spread to axillary lymph nodes before screening; this percentage increased to 78 per cent in the screen-detected cases. Forty per cent of ductal carcinomas showed a malignancy grade I before screening, compared to 53% in the screen-detected cases. Thirteen per cent were treated with breast conserving therapy before screening, as opposed to 48% in the screen-detected cases. Forty-one per cent needed postoperative adjuvant treatment before screening, compared with 21% in the screen-detected cases. Discussion: A marked improvement was seen in the prognostic and treatment-related characteristics of the screen-detected breast cancer cases, as compared to breast cancer cases from the same area before screening was initiated.
