An abnormally high increase in white blood cells is not necessarily leukemia.
People with leukemia may have elevated or decreased white blood cell levels. In the early stages of acute leukemia, the white blood cell count is decreased, only in the later stages, the white blood cell count is increased.
Leukemia is a condition in which the bone marrow abnormally proliferates and differentiates a large number of nonfunctioning white blood cells. Currently leukemia can be divided into hypoproliferative leukemia and hyperproliferative leukemia. Patients with hypoproliferative leukemia may not have high white blood cell counts. In addition, when leukemia occurs, the spleen engulfs the abnormal white blood cells, which can also lead to a decrease in white blood cell levels.
It is important to note that leukocyte levels can also be abnormally high when the body has an infection (eg, upper respiratory tract infection, skin infection, purulent infection, cellulitis) or in states other than ovulation, hunger, excitement, or emotional stress.
The diagnosis of leukemia should not be based solely on an increase in white blood cells, but also on bleeding, fever, bone pain, and so on.
