What type of cells are leukemia cells?

Leukemia is a malignant disorder of hematopoietic stem cells, typically arising from clonal proliferation of these stem cells, which disrupts normal blood cell production. This may lead to symptoms such as bleeding, anemia, fever, and infections. So, what exactly are leukemia cells?

What Are Leukemia Cells?

Leukemia cells are abnormally proliferating white blood cells resulting from a malignant clonal disorder of hematopoietic stem cells. Dysregulation in cellular proliferation, differentiation, and apoptosis leads to uncontrolled clonal expansion of white blood cells. These abnormal cells accumulate and proliferate within the bone marrow and may infiltrate other tissues and organs, thereby impairing normal hematopoiesis. Consequently, circulatory failure may occur, leading to hepatomegaly, splenomegaly, and lymphadenopathy.

Based on differences in cellular differentiation and disease progression, leukemia cells are classified into two main types: acute and chronic. In acute leukemia, the leukemic cells are typically arrested at an early stage of differentiation—most commonly promyelocytes—and the disease progresses rapidly over several months. In contrast, chronic leukemia cells retain relatively greater differentiation capacity and proliferate more slowly, often persisting for several years.

Patients with leukemia should follow a diet that is light, easily digestible, and rich in protein and vitamins. Increased fluid intake is also recommended to promote uric acid excretion and help prevent hyperuricemia. We hope this information is helpful to you.
