Overview of Leukemia
Classification of leukemia
Leukemias are grouped into four main types: Acute Lymphoblastic Leukemia (ALL) None Acute Myeloid Leukemia (AML) None Chronic Lymphocytic Leukemia (CLL) None Chronic Myeloid Leukemia (CML) None The types are defined according to how quickly they progress and the type and characteristics of the White Blood Cells that become cancerous. Acute leukemiasprogress rapidly and consist of immature cells. Chronic leukemiasprogress slowly and consist of more mature cells. Lymphocytic (lymphoblastic) leukemiasdevelop from cancerous changes in lymphocytes or in cells that normally produce lymphocytes. They may be acute or chronic. Myeloid (myelocytic, or myelogenous) leukemiasdevelop from cancerous changes in cells that normally produce neutrophils, basophils, eosinophils, and monocytes. They may be acute or chronic.
