Leukemia - Definition

Ask a question


Leukemia is a cancerous disease that affects the bone marrow cells. The bone marrow normally produces red blood cells, platelets, and white blood cells. Leukemia is essentially characterized by an abnormally high production of immature white blood cells, meaning those whose development is not yet completed, which invade the bone marrow and blood and can then migrate to other organs. Bone marrow becomes less functional and sets up a panel of myelosuppression with a result of decreased red blood cell production, anemia, decreased platelets, thrombocytopenia with a risk of bleeding, and decreased white blood cells with neutropenia, and the weakening of the immune system with the body exposed to infections. Various forms of leukemia exist and are studied by specialists.
