Breast Cancer Incidence Rates in Ghanaian and US Black Women From 2013 Through 2015.

ABSTRACT:

Importance

Uncertainty exists about whether women of West African ancestry have increased rates of estrogen receptor (ER)-negative breast tumors, which commonly have earlier age onsets than ER-positive tumors and are aggressive. High-quality population-based studies in Africa with tumor pathology data are generally unavailable, and there is speculation that younger population age structures may explain the increased frequencies of reported ER-negative tumors.

Objective

To estimate age-standardized and age-specific rates of ER-negative breast cancer among Ghanaian women and non-Hispanic Black and non-Hispanic White women in the US.

Design, setting, and participants

This cross-sectional study used 2013 through 2015 data from a population-based case-control study conduct
