Frequent fevers in children do not indicate leukemia. There is a big difference between the two, as children with leukemia have recurrent fevers due to lowered immunity and infections that cause recurrent fevers, not recurrent fever symptoms.
The main clinical manifestations of leukemia are fever, anemia, and severe bleeding, often with malaise, lethargy, such as bleeding gums, nasal bleeding, bleeding spots and petechiae on the skin, and painful enlargement of the liver and spleen lymph nodes in leukemia. In the case of leukemia, the white blood cells are significantly abnormally elevated or decreased, and the hemoglobin and platelet counts are reduced; the child has frequent fevers, mostly due to bacterial or viral invasion, resulting in fever caused by symptoms of upper respiratory tract infection, mainly due to poorer health and decreased resistance.
The first step to confirm the diagnosis of leukemia is to check the blood count, etc. If you want to confirm the diagnosis of leukemia, you need to do a bone marrow aspiration to see the bone marrow image to fully confirm the presence of leukemia; many clinical symptoms of fever are first considered to be caused by various infections, and the incidence of leukemia is actually not that high.
