Thirty years of population-based breast cancer screening in Iceland: a comparison of quality indicators and tumour characteristics between women aged 40-49 and 50-69 years.

ABSTRACT:

Background and purpose

Organised mammography screening reduces breast cancer mortality by 30-40% in women aged 50-69. Despite limited evidence for women aged 40-49, screening guidelines are trending toward younger ages. Iceland has offered biennial screening to women aged 40-69 since 1987. This study compares screening quality indicators and tumour characteristics between women aged 40-49 and 50-69 from 1990 to 2020. Patient/material and methods: Screening-related data were obtained from the Icelandic Breast Cancer Screening Program, and breast cancer diagnoses and tumour characteristics were sourced from the Icelandic Cancer Registry.

Results
