About The Study: In this cohort of Black women, living in disadvantaged neighborhoods was associated with a higher mortality from breast cancer, even after accounting for stage at diagnosis, treatments, and individual-level lifestyle factors. Community-level interventions to reduce environmental stressors and improve conditions in disadvantaged neighborhoods, including access to high-quality cancer care, may be critical to reducing racial disparities in breast cancer survival.
