Besides being a fellowship-trained breast surgeon and general surgeon, Dr. Farrugia completed a Ph.D. focusing on inherited breast cancer at Mayo Clinic in Minnesota. During this time, he discovered novel techniques to determine which mutations in the BRCA1 and BRCA2 breast cancer susceptibility genes cause breast cancer and which are harmless. For this work, he received an award from the United States Department of Defense that funded his research. Dr. Farrugia’s research has helped researchers around the world identify harmful mutations in these genes.
