The most common cancers in children are (childhood) leukemia (32%), brain tumors (18%), and lymphomas (11%).[7][14] In 2005, 4.1 of every 100,000 young people under 20 years of age in the U.S. were diagnosed with leukemia, and 0.8 per 100,000 died from it.[15] The number of new cases was highest among the 1–4 age group, but the number of deaths was highest among the 10–14 age group.[15]
