  • a Cancers are classified according to the third version of the ICCC.

  • b In summing up the total number of cancers, each case of leukemia, lymphoma, and CNS cancer is counted only once.

  • c A total of 4554 cancers were diagnosed among the 4473 children with cancer because some children experienced >1 cancer, in different diagnostic groups. Therefore, the total number of cancers by diagnostic group differs from the number of individuals with cancer.
