Metastatic Breast Cancer Advisory Board

MBC Advisory Board

The Metastatic Breast Cancer Advisory Board was created to help empower Canadians living with metastatic breast cancer (MBC) by providing patient-focused insights on issues related to those affected by and concerned about MBC.

The Advisory Board brings together the lived experience and knowledge of women living with MCB, women who have had early-stage breast cancer, and caregivers. Members will help identify and inform Rethink’s annual priorities for MBC initiatives and also take an active role in helping to create and roll-out education, advocacy and support initiatives that support the unique needs of MBC patients.
