The goal of this study is to examine the role of traffic related air pollution in relation to the risk of breast cancer. Vehicle exhaust is a major contributor to air pollution and contains thousands of chemical compounds, including some that are well-established human carcinogens. This study will make use of the extensive air monitoring system that has been set up throughout California that measures background and regional air pollution levels. Study subjects will include a diverse sample of 61,000 female participants from the Multiethnic Cohort Study* that reside in California. This project will also incorporate information on neighborhood factors, health behaviors, and genetic susceptibility.
