Leukemia Overview<br />Cancerous cells fill up the bone marrow and prevent healthy red cells, platelets, and mature white cells (leukocytes) from being made<br />Tumor suppressor genes are deactivated<br />
Chronic Lymphocytic Leukemia (CLL)<br />CLL cells (mutations) multiply and replace normal white blood cells in bone marrow<br />Spreads to blood stream<br />Failure of bone marrow<br />Almost never occurs in children<br />
Chronic Myeloid Leukemia (CML)<br /><ul><li> Increased and unregulated growth of mainly myeloid (bone marrow) cells in bone marrow
Accumulation of these mutated cells into the blood.
Mainly affects adults</li></li></ul><li>Acute Lymphocytic Leukemia (ALL)<br />Malignant (immature) white blood cells continuously multiply and are overproduced in the bone marrow<br />Causes damage and death by crowding out normal cells and by spreading to other organs<br />Most common in children but can also occur in adults<br />
Acute Myeloid Leukemia (AML)<br />Abnormal fast multiplying myeloid cells replace healthy cells, causing bone marrow to fail<br />Occurs in children and adults<br />
