Abstract

Background: Geographic differences in the incidence of cancers may suggest unique genetic or environmental exposures that impact the risk of acquiring cancer. This research aims to determine the incidence rate and geographical distribution of common cancers among Iranian children. Methods: In this ecological study, we extracted data that pertained to the incidence rate of common cancers among children from reports by the National Registry of Cancer and Disease Control and Prevention in 2008. A map of the cancer incidence rates was designed by using geographic information system. Results: The most common cancer sites among children were the hematology system, brain and central nervous system, and lymph nodes. The central provinces had the lowest cancer incidences. Conclusion: The considerable variation in incidence of childhood cancers in Iran suggests a possible potential environmental risk factor or genetic background related to this increased risk among children. © 2016, Shiraz University of Medical Sciences.
