“This is how medicine used to be,” Breast Surgeon Dr. Sonya Sharpless says about Cancer Treatment Centers of America® (CTCA). “That is a good thing.”

Originally from Canada, Dr. Sharpless earned her Doctor of Medicine degree at Queen’s University in Kingston, Ontario, in 1988. At the University of Manitoba, she completed a two-year rotating internship in 1989, followed by a residency in general surgery in 1994. She trained in Cadaveric Organ Retrieval for several years at the University of Manitoba, where she later served as Cardiothoracic Surgical Assistant and the surgical doctor on call in the Intensive Care Unit.

Dr. Sharpless came to the United States in 1995, completing a fellowship in surgical oncology, followed by a year of surgical oncology research at the University of Illinois.

Since 1995, Dr. Sharpless has cared for patients in large hospital settings and smaller clinics. From 2003 to 2014, she provided surgical oncology services in her own private practice. She has also served as Clinical Instructor in Surgical Oncology at the University of Illinois and Chicago Medical School and was Director of the Women’s Center at Lake Forest Hospital for several years. She joined the CTCA hospital near Chicago in February 2014.

Dr. Sharpless is Board Certified in General Surgery by the American Board of Surgery. She holds a medical license through the State of Illinois. She is a Fellow of the American College of Surgeons, and a member of the Society of Surgical Oncology, the American Association of Cancer Research, the American Society of Clinical Oncology and the American Society of Women Surgeons. She has been an invited speaker at national and international conferences and has published research on breast cancer in several scientific journals.

At CTCA, Dr. Sharpless is focused on the treatment of breast cancer. She particularly enjoys the friendly atmosphere among both patients and colleagues. “People are genuinely happy to be here,” she says. “This is what medical care should be like.”
