Inequalities in breast cancer incidence and mortality in women with and without disabilities in South Korea: A population-based cohort study.

ABSTRACT:

Objective

Women with disabilities often face functional limitations and comorbidities that increase cancer risk. This study investigated breast cancer incidence and mortality among women with and without disabilities in South Korea.

Methods

We analyzed 2.87 million cancer-free women aged ≥30 who participated in the 2002-2003 national health screening program, linking the National Health Insurance Database, Cancer Registry, and cause-of-death records (2003-2019). Standardized incidence ratios (SIRs), standardized mortality ratios (SMRs), and mortality-to-incidence (M/I) ratios were calculated by disability status. Cox proportional hazards models with piecewise follow-up estimated adjusted hazard ratios (aHRs) for breast cancer outcomes.

Results

Among 296,689 women with
