Last fall, the California Breast Cancer Research Program (CBCRP) launched the Global Challenge to Prevent Breast Cancer with a goal of surfacing transformative breast cancer prevention research ideas. Dr. Hannah Lui Park was one of 10 finalists selected to present their ideas and compete in the live and live-streamed Idea Showcase and Competition on May 15th in San Francisco, California. Her idea was to explore In Utero and Pre-conception determinants of breast cancer in order to drive Personalized Breast Cancer Prevention. All 10 finalists’ 5-minute pitches as well as Dr. Susan Love’s keynote presentation can be seen here: http://www.cbcrp.org/global-challenge/livestream.html
