Nemours Children's Center for Cancer and Blood Disorders

The goal of our work in cancer and blood disorders is, very simply, to find a cure. To do so, we’re constantly searching for new biomarkers (molecules that show whether bodily conditions are normal or cancerous) and better treatments.

Our work is organized within the Nemours Children's Center for Cancer and Blood Disorders (NCCBD), a pediatric cancer center that includes our clinical and pediatric cancer research programs at the Nemours Children’s Hospital, Delaware, Nemours Children’s Hospital, Florida and Nemours Children’s Health, Jacksonville, Orlando and Pensacola, Fla. Each of our locations has been recognized for having outstanding participation in clinical trials, and for clinical trial access and management.
