Abstract 745: Circulating plasma metabolites and breast cancer risk

Metabolite profiles reflect the integrated impact of the genome and exogenous exposures on the metabolic state and may provide insight into biologic mechanisms contributing to breast cancer development. To better understand this, we explored the association between pre-diagnostic plasma metabolites (N=307) and breast cancer among women in the Nurses9 Health Study. Plasma metabolites were profiled for cases and controls via liquid chromatography tandem mass spectrometry (LC-MS) using samples taken ≥10 years prior to diagnosis (distant, N=939 cases), and Citation Format: Kristen D.
