Incidence Rate Trends of Breast Cancer Overall and by Molecular Subtype by Race and Ethnicity and Age.

ABSTRACT:

Importance

Black and Hispanic women in the US experience higher incidence rates of aggressive molecular subtypes of breast cancer, including triple-negative disease. However, how these rates are changing, particularly across different age groups, has not been well documented.

Objective

To assess changes in overall and subtype-specific breast cancer incidence rates in the US by age and race and ethnicity.

Design, setting, and participants

This cohort study used Surveillance, Epidemiology, and End Results program cancer registry data from 22 US cancer registries on 1 123 658 females who received a diagnosis of invasive breast cancer from 2010 to 2019. Statistical analysis was conducted from August 2023 to October 2024.

Exposures

Age and race and ethnicity.
