Dr. Arnaout is part of the Ottawa Breast Cancer Biomarker Research Program, whose mandate is to develop patient centered translational breast cancer research to better the lives of women struggling through the diagnosis and treatment now. Working closely with Dr. M. Clemons (a Medical Oncologist) and Dr. C. Addison (Senior Scientist at OHRI), they have formulated the ACA team, whose approach of working together means that research findings can be rapidly translated to improve the care of women in the clinic and operating room. This research includes biomarker predictors of treatment response and future metastatic disease. She leads several "window of opportunity" clinical trials with the ultimate goal of expediting drug development in breast cancer and reducing the anxiety of patients who are waiting for definitive surgical treatment.   Dr. Arnaout’s research is also committed to improving access and delivery of high quality care to breast cancer patients in Ontario. She is the leader of two specialty programs for breast cancer patients in Ottawa that fast track patients from diagnosis to treatment. 

Dr. Angel Arnaout is a Breast Surgical Oncologist at the Ottawa Hospital, Clinical Investigator at the Ottawa Hospital Research Institute, and Assistant Professor at the University of Ottawa. In addition to her clinical and scientific reserach interests, her passion as a surgeon is to aggressively treat breast cancer but with minimal side effects and cosmetic detriment, recognizing the importance of body image on the breast cancer patient. As such is also the pioneer in Oncoplastic Surgery in Ottawa; a new minimally invasive breast surgical technique that combines breast cancer surgery with plastic surgical techniques.
