What is Acute Lymphoblastic Leukemia (ALL)?

  • In the form of leukemia known as acute lymphoblastic leukemia (ALL), a group of white blood cells called lymphocytes is affected. Also called acute lymphocytic leukemia or acute lymphoid leukemia, ALL progresses very quickly and requires immediate treatment. Although ALL most commonly affects children (usually between the ages of 2 and 3), it also affects adults. Leukemias as a group are the most common form of cancer in children, accounting for about 30 percent of childhood cancers and affecting about 3,800 children each year in the United States. About 80 percent of children with leukemia have acute lymphoblastic leukemia.
