Investigating the link between PFAS chemicals and breast cancer risk in diverse populations

A nested case-control study of perfluoroalkyl and polyfluoroalkyl substances (PFAS) and breast cancer risk in the Multiethnic Cohort

NIH-funded research University of Southern California · NIH-11059222

This study is looking at whether being exposed to certain chemicals called PFAS can increase the risk of breast cancer in women from different backgrounds, especially those in low-income communities, by checking their blood samples and health information.

What this research studies

This research aims to explore the relationship between exposure to per- and poly-fluoroalkyl substances (PFAS) and the risk of developing breast cancer among a diverse group of women. By analyzing pre-diagnostic blood samples and comprehensive data on breast cancer risk factors, the study seeks to identify whether higher levels of PFAS are associated with increased breast cancer risk. The research will focus on various racial and ethnic groups, particularly those in low-income communities who may have higher PFAS exposure. The methodology includes a nested case-control design within the Multiethnic Cohort, allowing for a thorough examination of genetic, metabolic, and environmental factors.

Who could benefit from this research

Good fit: Ideal candidates for this research include women from diverse racial and ethnic backgrounds, particularly those living in low-income communities in California and Hawaii.

Not a fit: Patients who do not reside in the study areas or who do not have a history of breast cancer may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to better understanding and prevention strategies for breast cancer, particularly among high-risk populations.

How similar studies have performed: While some studies have suggested a link between PFAS and breast cancer in primarily white populations, this research is novel as it focuses on a diverse cohort and aims to provide more comprehensive data.
