Endocrine-disrupting chemicals (EDCs) are known contributors to breast cancer development. EDC exposures commonly occur through food packaging, cookware, fabrics, and personal care products as well as through the environment. Increasing evidence highlights disparities in EDC exposure across racial/ethnic groups, yet breast cancer research continues to lack the inclusion necessary to positively impact treatment response and overall survival in these socially disadvantaged populations. Additionally, the inequity in environmental exposures has yet to be remedied. Exposure to EDCs due to structural racism poses an unequivocal risk to marginalized communities. In this review, we summarize recent epidemiological and molecular studies on two lesser-studied EDCs, per- and polyfluoroalkyl substances (PFAS) and parabens, the health disparities that exist in EDC exposure between populations and their association with breast carcinogenesis. We discuss the importance of understanding the relationship between EDC exposure and breast cancer development, particularly to promote efforts to mitigate exposures and improve breast cancer disparities in socially disadvantaged populations.
