In the United States in 2024, an estimated 13,000 new cases of cancer will be diagnosed among children from birth to 14 years, and about 1,040 children are expected to die from the disease. Although cancer death rates for this age group have declined by 70 percent from 1970 through 2020, cancer remains the leading cause of death from disease among children. The most common types of cancer diagnosed in children ages 0 to 14 years are leukemias, brain and other central nervous system tumors, and lymphomas. The Division of Cancer Epidemiology & Genetics (DCEG) investigators study factors associated with childhood cancer to improve understanding of their causes to inform prevention and treatment of these malignancies. They also study the late effects of treatment and other long-term outcomes for survivors of childhood cancers.
