Dr. Chan treats both benign and malignant breast conditions and focuses on a multidisciplinary, evidence-based approach to caring for each patient as a whole individual.  Her training in breast surgery enables her to offer patients comprehensive breast cancer care in collaboration with Radiation Oncology, Medical Oncology, and Plastic Surgery.  She is a member of the American College of Surgeons, Association for Academic Surgery, American Society of Breast Surgeons, and Society of Surgical Oncology.
