Leukemia is a malignant blood disease caused by the overproliferation of a certain blood cell system in children’s hematopoietic tissues and infiltration of other organs and tissues. Because the early symptoms of childhood leukemia may be related to the severity, genetic factors, viral infections, physical conditions and other influencing factors, so early symptoms vary from person to person, there is no so-called seven symptoms of early childhood leukemia, common early childhood leukemia symptoms include the following: 1, fever: some children with leukemia can appear early more typical symptoms, such as fever, anemia, etc., but the fever The fever type is usually different, it can be low fever, persistent high fever or irregular fever, usually not accompanied by chills, usually antibiotic treatment can not play a role; 2, anemia: some children in the early stage of anemia symptoms, mainly manifested as mental depression, low appetite, weakness, pale, shortness of breath after activity, etc., and will be aggravated with the development of the disease, mainly related to the inhibition of bone marrow hematopoietic stem cells Bleeding: Most of them are skin and mucous membrane bleeding, such as gum bleeding, nasal bleeding, and skin bleeding petechiae, and a few children with leukemia may even have intracranial bleeding. In addition, due to individual differences, some children may also show symptoms such as enlarged liver, spleen, lymph nodes, bone and joint pain or lesions in the early stages of leukemia. These symptoms are usually indicative of leukemia cell infiltration, which can lead to headaches, drowsiness, and vomiting. Because most children with leukemia have atypical early symptoms, they can be confused with other diseases, which can lead to misdiagnosis. Children with these symptoms should go to the hospital for routine blood and bone marrow cytology tests, which usually show abnormal platelet and white blood cell levels, to improve their quality of life through early diagnosis.
