Crude incidence, age-specific incidence, and standardized incidence rates of leukemia in children under 14 years of age in Iran: an updated meta-analysis.

Background: Cancer is the second leading cause of death in children aged 0-14 years and leukemia is the most prevalent of them among children in the world and Iran. Estimating cancer incidence is a vital tool in epidemiology and subsequent cancer control programs.
