Lifetime dairy product consumption and breast cancer risk: a prospective cohort study by tumor subtypes.

ABSTRACT:

Background

Previous literature on dairy products and risk of breast cancer is inconsistent, and the relationship may depend on the life-period of dietary assessment.

Objective

We examined dairy consumption from adolescence through later adulthood and incidence of breast cancer by menopausal status and tumor molecular subtypes in the Nurses' Health Study (NHS), a prospective cohort study.
