Summary of Research

Dr. May Lynn Quan is a health services and clinical researcher in oncology, focusing primarily on delivery of care, quality and outcomes for women with breast cancer.  She is the Scientific Director of SPHERE - Strategies for Precision Health in Breast Cancer, funded through a donation from Arnie Charbonneau to the University of Calgary and grants from CIHR-ICR, the Canadian Cancer Society, Alberta Innovates, the Breast Cancer Society, the Yates Memorial Endowment for Cancer Research and the Medical Services Inc (MSI) Foundation. 

SPHERE supports a core team of scientists, analysts with program management, research assistants and data management with a focus on providing a collaborative research environment for trainees at the undergraduate, graduate, post doctoral,  resident and fellowship levels. Starting in 2024, a research fellowship has been created to further support training of future researchers in breast oncology.



Current Research

Dr. Quan highly values collaborative research. She is currently the co-Principal Investigator on RUBY, a pan-Canadian collaborative project to create a prospective cohort of women 40 years of age and under newly diagnosed with breast cancer in order to help better understand the support needs of these women, along with improving treatment and outcomes. The cohort has collected blood, tissue and patient reported outcomes from diagnosis to 5 years from over 1500 women from 32 sites across Canada. The study is co-funded by the Canadian Cancer Society and the Canadian Institutes of Health Research (CIHR-ICR) and has lead to additional grants supporting the unmet needs of this population through the co-development of SAPPHIRE, an App created with patients to accompany them through their cancer journey funded by a grant from the Alberta Cancer Foundation and the Canadian Cancer Society.
