Key Points Question Is historical mortgage lending discrimination (1930s redlining) associated with recent breast cancer outcomes differently by race and ethnicity? Findings In this cohort study of 14 964 breast cancer cases, we found evidence that residence at diagnosis in areas historically graded “best” (vs residence in redlined areas) was associated with lower odds of late-stage diagnosis, lower odds of high tumor grade, lower odds of triple-negative subtype, and lower hazard of breast cancer–specific death, but only among non-Latina White women. Meaning These findings suggest that historical structural racism may be associated with beneficial cancer outcomes among privileged racial and ethnic groups.
