Screen-Detected Breast Cancer Outcomes by Mammography Participation in Immediate Past Screening.

ABSTRACT:

Importance

Mammography screening is essential for the early detection of breast cancer; however, delayed detection among screen-detected breast cancers (SDBCs) is rarely studied.

Objectives

To investigate whether women diagnosed with SDBC who missed the screening round immediately before the diagnostic round experience clinically significant delays in detection and whether tumor characteristics vary.

Design, setting, and participants

This prospective register-based cohort study included all women diagnosed with SDBC in Stockholm, Sweden, between January 1, 1995, and February 28, 2020, with a follow-up until December 31, 2022. Data were analyzed from November 5, 2023, to May 27, 2024.

Exposure

Nonparticipation in the screening immediately prior to the diagnostic
