Definition

A type of acute myeloid leukemia (AML) that is caused by previous treatment with chemotherapy or radiation therapy. t-AML is an aggressive (fast-growing) cancer in which there are too many myeloblasts (immature white blood cells) in the blood or bone marrow. t-AML usually occurs within 7 years after treatment. It is more common in adults. Also called therapy-related acute myeloid leukemia.
