Description
The Breast Cancer Research Foundation (BCRF) launched this initiative to investigate why breast cancer is occurring at increasing rates in younger women and why early-onset and postpartum disease may be more aggressive or respond differently to treatment. It seeks testable explanations at the molecular, genetic, cellular, and tissue levels, with findings that could inform prevention, interception, or improved outcomes.
Areas of interest include tumor biology; postpartum breast cancer and involution; mechanisms linking environmental exposures and modifiable risk factors to disease; and changes in normal breast biology across reproductive life. BCRF particularly welcomes work on immune mechanisms connecting these areas. Projects should move beyond description toward mechanism and causality, connect discovery to clinical relevance, and produce meaningful findings throughout the grant period.
