Wednesday, August 13, 2025 Please join us in congratulating our friend and colleague, Timothy Whelan on his appointment to the Order of Canada. He is a world-class radiation oncologist and his research has redefined radiation therapy’s use in the treatment of breast cancer, improving survival rates and limiting side effects. He has mentored many trainees, solidifying the reputations of McMaster University and the Juravinski Cancer Centre as leaders in oncology clinical trial training. Dr Whelan was the past co-Chair of CCTG's Breast Site Committee and is the chair of CCTG MA.39 clinical trial. He also led the CCTG MA.20 trial, which showed that the addition of regional nodal irradiation to whole breast irradiation after breast conserving surgery reduced the risk of breast cancer recurrence, leading to the wide adoption of this approach for women with node-positive breast cancer. https://www.gg.ca/en/order-canada-appointees-june-30-2025
