Dr. Ley is a breast surgical oncologist who has practiced in the Tucson community since 2006. She provides high quality, compassionate, and personalized care for each patient, working with Arizona Oncology’s team of breast cancer, medical oncology, radiation oncology, and genetics specialists to develop a comprehensive treatment plan based on the latest research. 

Dr. Ley specializes in surgical care for breast cancer patients, including minimally invasive biopsies, axillary node preserving procedures, nipple-sparing mastectomies, and treatment of high-risk patients. 

Dr. Ley previously served as Director of Breast Surgery and Associate Professor of Surgery at the University of Arizona. She also serves as Medical Director of TMC’s Breast Health Program. 




I enjoy getting to know my patients and their families. I strive to understand the experiences, values, and influences that shape each patient’s life and response to illness and treatment. This holistic view helps me to collaborate with my patients to plan the surgical therapy that will provide the most successful outcome for their diagnosis, while helping them achieve the best possible quality of life. I aim to communicate with my patients frankly, yet gently, and with empathy. No matter our background, we are all people with challenges, successes, and feelings.
