Acute megakaryoblastic leukemia is also known as acute magakaryocytic leukemia. It is a type of cancer affecting the blood. Although the precise cause of this disorder is not fully understood, exposure to radiation or certain chemicals is considered risk factors for this condition. Acute megakaryoblastic leukemia may cause various symptoms such as bruises, excessive bleeding, fatigue and fever. A physician can often diagnose this condition with a physical exam and blood tests, although certain imaging studies such as an x-ray or CT scan might be necessary. Treatment for cancers of the blood, including acute megakaryoblastic leukemia, is rapidly progressing with advances in medical research. Currently, chemotherapy and bone marrow transplant are two possible treatment options.
