Leukemic cell is a blood cell that is not related to leukocytes, appearing in the blood during acute leukemia. It occurs in the form of multinucleated giant cells. Contain a different number of cores. Normally, such cells are usually absent. Impaired growth and maturation of leukemia cells can lead to the formation of cancer cells. When favorable conditions arise, they begin to actively divide, capturing healthy cells, disrupting the immune system, changing the composition of the blood. Such cells can produce a large number of leukocytes, which is not typical for healthy ones.
