Background: Childhood cancers include a variety of malignancies with variable incidence by age, sex, ethnicity and geographic region. Cancers in children has been reported to have different patterns in various countries of the world. We have previously described the pattern of childhood cancer in Iraq during a five-year period (2000-2004). The aim of this paper is to describe the most recent pattern of cancer by primary site in Iraqi children observed during four-year period (2015-2018).
