Introduction: Childhood cansers are the second leading cause of death among children. Since the incidence and prevalence of malignancies are different in different regions and there are several cultural and environmental factors involved, the aim of this study was investigating epidemiology of common malignancies in children in Hamedan Province during the years of 1386-1395. Methods: In this cross-sectional study, the population study was the children with  malignancies referred to Besat's Hospital in Hamadan Province. The collected data were analyzed using SPSS 20 software. Descriptive indices and Chi-square test were used in this study. Results: All available records showed that the malignancy was more prevalent in boys in freqency (57/7%). Most acute lymphoblastic leukemia (ALL) patients were 1-9 years, most acute myeloid leukemia (AML) patients were older than 9 years and most other malignancies were 1-4 years and over 9 years. The number of blood platelets (PLT) and the white blood cells (WBC) of the majority of patients in other malignancies, respectively, were greater than 100,000 and less than 50,000. For acute lymphoblastic leukemia and acute myeloid leukemia patients, the number of PLT and WBC  were less than 100,000 and less than 50,000, respectively. The most clinical symptoms for acute lymphoblastic leukemia patients were fever and pale,  fever and bleeding for acute myeloid leukemia AML patients, and finally masses and fever for patients with other malignancies. Conclusion: Although the results of the family cancer were consistent with expected results concluded of similar studies, but  the incidence of other malignancies in females was different (51/1%) with the results of some other studies.
