How do leukemias affect bone marrow function?

• A. They enhance production of normal blood cells
• B. They lead to overcrowding of leukemic cells
• C. They improve the immune response
• D. They have no impact on bone marrow

Answer: (B)

Leukemias are characterized by the uncontrolled proliferation of abnormal white blood cells within the bone marrow. This overproduction of leukemic cells leads to overcrowding in the bone marrow, which ultimately impairs its ability to produce normal blood cells, including red blood cells, other white blood cells, and platelets. As a result, patients often experience severe consequences such as anemia, increased susceptibility to infections, and bleeding tendencies due to the inadequate production of these vital components of the blood. Thus, the correct understanding of how leukemias affect bone marrow function centers on the overcrowding of leukemic cells that disrupts normal hematopoiesis.
