Alcohol, Breast Cancer, and Metabolism
Localized Mammary Alcohol Metabolism as a Mechanism Linking Low-Level Alcohol Intake to Breast Cancer Risk
University of Illinois at Urbana-Champaign
50 participants
Sep 3, 2026
INTERVENTIONAL
Conditions
Summary
Alcohol consumption, even at low levels, has been associated with increased breast cancer risk, but the biological mechanisms underlying this relationship remain unclear. This study will examine whether breast tissue may locally metabolize alcohol by measuring alcohol-related compounds in paired blood and breast milk samples from lactating women. The findings may help clarify alcohol-related biological pathways relevant to breast cancer risk and improve risk communication.
