Dr. Steven Narod is a world-leader in the field of breast and ovarian cancer genetics. Over the course of his career, he has profoundly shaped current knowledge of how to assess breast and ovarian cancer risk and reduce its mortality amongst carriers of BRCA1 and BRCA2 mutations. He studies various aspects of cancer prevention and screening, proving that prophylactic surgeries and medications can prevent hereditary breast/ovarian cancers. For women unwilling to undergo radical surgeries, he is pinpointing dietary options that reduce risk.

Dr. Narod has identified founder mutations in a number of traditionally isolated ethnic populations, including people of French-Canadian, Bahamian and Ashkenazi Jewish descent. His database of nearly 13,000 women from 30 countries supports numerous international collaborations in countries around the world, advancing cancer genetics in North America, Asia, Europe the Caribbean and Latin America. Most recently, his collaborative research has proven that women in Poland carrying a BRCA1 mutation have a substantially lower risk of breast cancer than women in North America with the same mutation. His recent research has also revealed that, while one per cent of Jewish women in Ontario carry a BRCA1/2 mutation, fewer than half of these women qualify for provincially-funded genetic screening. 

Dr. Steven Narod is a Tier I Canada Research Chair in Breast Cancer, a University of Toronto professor in the Dalla Lana School of Public Health and the Department of Medicine, and a senior scientist at Women’s College Research Institute, where he leads the Familial Breast Cancer Research Unit.

In 2012, Dr. Narod was elected a Fellow of the Royal Society of Canada. With more than 550 peer-reviewed publications and an H-index of 85, Dr. Narod is the most-cited researcher in the world in the field of breast cancer.
