Breast Cancer Canada and the Canadian Society of Surgical Oncology (CSSO) are proud to announce the BCC–CSSO Career Development Research Award. This new initiative is focused on the growth of Canada’s surgical oncology talent pipeline. An investment of $200,000 will help keep Canada’s top breast cancer surgeons here at home by supporting early-researchers at a critical stage in their careers. The goal? To see patients across the country benefit from world-class expertise, innovative research, and high-quality, evidence-based breast cancer surgery: by Canadians, for Canadians. We are pleased to announce Dr. Matthew Castelo as the inaugural award recipient. His research project, PROTECT, will explore the variation in breast cancer surgical care across Canada.

Timely @JCO_ASCO commentary on CNS surveillance for MBC by @JerzakKasia et al. Mixed recommendations from international societies, informed by practices that predated novel RT techniques (eg SRS) and brain-active drugs (ADCs, TKI). Urgent call to action. ascopubs.org/doi/pdf/10.1200…

Looking forward to Dr. Osman joining our Breast Surgical Oncology team @WCHospital on July 1st! @UofTGSx @UofTSurgery
Dr. Fahima Osman arrived in Canada as an 11-year-old refugee, and grew up the eldest of 9 kids. Today, she is a surgical oncologist and the first Somali refugee to become a doctor in Canada. This great @globeandmail piece about Dr. Osman is a must-read. bit.ly/3Ful2Vh
