Translating Today's Discoveries in Childhood Cancer Research into Tomorrow's Treatments.

The Greehey Children’s Cancer Research Institute is one of only two institutes in the United States exclusively focused on pediatric cancer research. With 19 laboratories, the institute leverages expertise in cancer genomics, DNA repair, RNA biology, and drug development to discover new and less harmful treatments for childhood cancers.
