Childhood Cancer Research Network: a North American Pediatric Cancer Registry

Abstract

Nearly 12,500 children under the age of 20 years are newly diagnosed with cancer each year in the United States (3). The incidence of childhood cancer has been increasing slightly, but significantly, over the last several decades, particularly among White children (4). Confirmed risk factors for childhood malignancy are few, but a growing body of evidence suggests environmental exposures play a role (5).
