Global evolution of breast cancer incidence in childbearing-age women aged 15-49 years: a 30-year analysis.

ABSTRACT:

Background

Breast cancer (BC) poses an increasing threat to women's health, yet its characteristics in women of childbearing age (WCBA) are infrequently reported. This study aims to investigate the patterns and trends in BC incidence among WCBA over the past decades.

Materials and methods

This study focuses on BC incidence in women aged 15-49 years, consistent with the WHO definition of WCBA. Estimates and 95% uncertainty intervals (UIs) for BC incidence in WCBA were obtained from the Global Burden of Diseases Study 2021. We utilized an age-period-cohort (APC) model to estimate the overall annual percentage change in incidence (net drift, % per year) and the annual percentage change within each age group (local drift, % per year). This model also provided fitted longitudinal
