Frequency of chronic hemoblastosis and age features

In the structure of oncological morbidity, among malignant tumors of other localizations, hemoblastoses occupy the 5th-6th place. It is noticed that men suffer from hemoblastoses more often than women, and rural residents less often than the urban population. In children of the first 5 years of life, acute lymphoblastic leukemia prevails with an absolute frequency in persons aged 20-45 years - chronic myeloid leukemia. The search for adequate ways of prevention, early detection and effective treatment of hematological malignancies is the most acute problem of oncohematology.
