The Breakthrough Bike Challenge (BBC) supports Penn Medicine's Abramson Cancer Center in a unique way. It funds scientists with bold and innovative ideas for early stage cancer research that can lead to "breakthroughs" in cancer solutions. Seed capital for early stage research is one of the most underfunded parts of the cancer research process. Yet it is often the source of "breakthroughs" in cancer reserach. BBC's mission is to bridge that gap in funding.
