Residential exposure to vehicular traffic-related air pollution during childhood and breast cancer risk.

ABSTRACT:

Background

Some studies have supported an association between traffic-related air pollution exposure and breast cancer risk. However, few studies have considered exposures in early life, which may be a period of increased susceptibility.

Objectives

To examine the association of childhood residential exposure to traffic-related air pollution with breast cancer development.

Methods

The Sister Study is a prospective cohort of 50,884 initially breast cancer-free women, of whom 42,934 provided information at enrollment about roads and traffic near their primary childhood residence before age 14 as well as relevant covariates. Adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) for the association between traffic-related measures at childhood residence and adul
