Diagnosed with de novo Metastatic Breast Cancer (MBC) in July 2020, Mary speaks publicly about her experiences since diagnosis, and she serves as a voice for those who are uncomfortable telling their own stories and for those who no longer can. As an advocate, Mary seeks to provide support and information—and hope—to newly-diagnosed folks, influence better policy and research outcomes, participate in identification and resolution of support service gaps (especially for historically marginalized communities), help healthcare providers increase cultural competency and person-first language, and make “patient-centered” more than a buzzword. She has several projects under development, including “CancerAside”—a regular sub-series of her soon-to-be-launched social justice podcast, “CosEffect.”
