To test this hypothesis the investigators will focus on studying BC patients using an innovative approach, the DIGNITY Study (De-convoluting interactions between genes, the cancer environment, and the immune system to develop therapies that work for you) designed to building a live tissue biobank of Patient Derived Tumor Organoids (PDOs) derived from tumor at surgery, preceded or not by neoadjuvant therapy (NAT), and at recurrence/metastasis. BC patients enrolled in this study are consented to enable investigators to generate a biobank of tumor tissue (obtained from surgically removed excess that would otherwise be disposed off ) and matched blood cells ( obtained from an already existing line or a venipuncture ordered per standard of care testing) at key timepoints in their treatment course.
