Adult acute myeloid leukemia (AML) is a cancer of the blood and bone marrow. AML is also called acute myelogenous leukemia, acute myeloblastic leukemia, acute granulocytic leukemia, and acute nonlymphocytic leukemia. This type of cancer is the most common type of acute leukemia in adults and usually advances quickly if not treated immediately. See Adult Myeloid Leukemia for signs, symptoms and treatments.
