Research Summary

Dr. Cheryl Ewing is Associate Professor of Surgery at UCSF Mount Zion Hospital. Her focus is in breast cancer surgery and sentinel lymph node dissection. Her other interests include quality of care and evaluation of barriers to medical and breast care for minority women.

Dr. Ewing completed her undergraduate education at the University of Michigan, and received her medical degree from Wayne State University School of Medicine. She then went on to complete her residency at University of Michigan Medical School, and then her fellowship at the University of Chicago. She joined the faculty at UCSF in 2001.

Dr. Ewing has lectured extensively at many local, national, and international events. She has been very active in mentoring residents and fellows, serving four years as the Mount Zion Site Director for the Surgery 110 Rotations and teaching several CME courses and Grand Rounds.

Dr. Ewing is involved in several studies involving quality of care among breast cancer survivors. Specifically, these involve post-surgery symptom management, and customizing risk assessment and tailoring treatment to the individual patient's medical profile and preferences. Her primary focus in on how being a breast cancer survivor affects the quality of life in different race/ethnic groups, and how that relationship is modified by social support, depression, and spirituality.

Dr. Ewing is a member of most of the major surgical societies, and has been the recipient of several awards, including the Susan G. Komen Local Hero Award.
