Population-based cohort study of neighborhood deprivation and breast cancer mortality among Black and White women

Neighborhood deprivation has been associated with increased breast cancer mortality among White women, but findings are inconsitent among Black women, who experience different neighborhoods contexts. A population-based cohort study using Georgia Cancer Registry data on 36,795 women with breast cancer diagnosed in 2010 to 2017 and followed-up until December 31, 2022, found that neighorhood deprivation was associated with increased breast cancer mortality among non-Hispanic White women, but not among non-Hispanic Black women, regardless of the modifying neighborhood characteristics considered. The authors conclude that these findings suggest that factors beyond neighborhood deprivation may contribute to increased breast cancer mortality among Black women.
