I believe that the care of every patient should be tailored to his/her disease process, other medical conditions, and goals of treatment. My philosophy is to provide multidisciplinary care that offers patients all available options, including the most recent treatment advances and participation in clinical trials. The end result is an individualized treatment plan that addresses the disease but also values each patient’s unique perspective regarding care.

Clinic Locations


Dr. Yen joined the Medical College of Wisconsin in 2004, after completing her surgical oncology fellowship at the University of Texas M.D. Anderson Cancer Center. Her clinical practice is devoted solely to patients with breast cancer and tumors of the endocrine system (thyroid, parathyroid and adrenal gland). She is the Service Chief for Breast and Endocrine Surgery at Froedtert Hospital.

Dr. Yen’s research program is also devoted to breast cancer and endocrine surgery. Her funded breast cancer health services research is focused on quality of care, patterns of care and the relationship of these patterns of care to outcomes of care. Her research has examined lymphedema (arm swelling) after breast cancer treatment, processes of breast cancer care, and adoption of sentinel lymph node biopsy. Dr. Yen is also active in clinical trials and is the institutional principal investigator for the Alliance for Clinical Trials in Oncology, a national clinical trials network sponsored by the National Cancer Institute (NCI).

Dr. Yen is a fellow of the American College of Surgeons, and a member of the editorial boards of Annals of Surgical Oncology and Surgery.  She holds several national leadership positions, including Recorder for the Central Surgical Association, editorial board member for the Surgical Council on Resident Education, and member of the American College of Surgeons Advisory Council for General Surgery.
