Maggie L DiNome

Professor of Surgery
Surgical Oncology
4101 Macon Pond Road, Raleigh, NC 27607

Overview


I am a faculty member at Duke in the Department of Surgery, Division of Surgical Oncology. I am a surgical breast oncologist whose clinical research interests focus on the de-escalation of axillary surgery for patients with lymph node positive breast cancer. My translational research interests focus on epigenetic modifications in breast cancer. I have returned to Duke (Medical School 1994), having spent the past 20 years in Los Angeles, most recently at UCLA where I served as Chief of Breast Surgery and Director of Breast Health for the UCLA Health System. I am honored to have joined the Duke faculty and am eager to grow the program in Wake County as the medical director of breast cancer services.
