Age-Specific Incidence of Breast Cancer Subtypes: Undrstanding the Black-White Crossover

Breast cancer incidence is higher among black women than white women before age 40 years, but higher among white women than black women after age 40 years (black-white crossover).

Description
Summary:Breast cancer incidence is higher among black women than white women before age 40 years, but higher among white women than black women after age 40 years (black-white crossover). Here, Clarke et al use newly available population-based data to examine whether the age-specific incidences of breast cancer subtypes vary by race and ethnicity. Results show that the black-white crossover in breast cancer incidence occurs only when all breast cancer subtypes are combined and relates largely to higher rates of triple-negative breast cancers and lower rates of HR+/HER2-breast cancers in black vs white women.
