Air pollution and breast cancer risk in the Black Women's Health Study.

ABSTRACT:

Background

Air pollution contains numerous carcinogens and endocrine disruptors which may be relevant for breast cancer. Previous research has predominantly been conducted in White women; however, Black women may have higher air pollution exposure due to geographic and residential factors.
