Breast Cancer Disparities — One’s Neighborhood Can Significantly Impact BCSS

Objective: To determine the association between living in disadvantaged neighborhoods in New York City with tumor grade and breast cancer (BCa)-specific survival (BCSS). Design: Retrospective, single-center cohort study. Methods: The authors identified BCa patients from their prospectively maintained institutional database. Patients who lived in New York City and underwent surgery at their institution between 2013 and 2024 were included in the study.

The authors determined the association between tumor grade and living in a disadvantaged neighborhood. Results: 5452 women with stage I to III BCa were identified, with 3479 (64%) living in advantaged neighborhoods and 1973 (36%) living in disadvantaged neighborhoods. Women living in disadvantaged neighborhoods were significantly younger than those living in advantaged neighborhoods. A hi more...
