What type of cells are predominant in leukemic individuals?

In individuals with leukemia, the predominant cells are typically immature leukemic cells, which are also known as blasts. These cells arise from the uncontrolled proliferation of leukemic stem cells, resulting in a large number of immature white blood cells that crowd out normal cells in the bone marrow and bloodstream. This overproduction of immature cells is a hallmark of leukemia and is responsible for the various symptoms associated with the disease, including anemia and increased susceptibility to infections.

Normal lymphocytes and normal granulocytes are not typically found in predominance in leukemic patients; instead, their numbers are often reduced due to competition for space and resources in the bone marrow from the leukemic cells. Platelets are also not predominant in leukemic individuals; in fact, platelet counts can be decreased due to impaired production and increased destruction in some types of leukemia. Therefore, the distinguishing feature of leukemia is indeed the presence of these immature leukemic cells.
