This document discusses acute leukemia, including: 1. Acute leukemia is cancer of the blood and bone marrow characterized by excessive production of immature white blood cells. It is classified as either acute myeloid leukemia (AML) or acute lymphoblastic leukemia (ALL) based on the affected cell type. 2. Signs and symptoms include fatigue, infections, bruising, and bleeding due to low red blood cell, white blood cell, and platelet counts. Diagnosis involves blood and bone marrow tests showing excessive blasts. 3. Treatment involves chemotherapy, blood transfusions, antibiotics, and sometimes stem cell transplant, with the goal of inducing remission and reducing blast counts.
