Medical Advisory Board

The mission of Living Beyond Breast Cancer’s Medical Advisory Board is to serve as an expert resource on issues of concern to people affected by breast cancer and their families and to assist with outreach to other health professionals and consumers about the breadth of LBBC programs for people affected by breast cancer.

Many Medical Advisory Board members help with reviewing content for our website and publications, serve as speakers at our events and help answer your questions about breast cancer during our ask-the-expert series.
