Acute Lymphocytic Leukemia Facts

Acute lymphocytic leukemia (ALL) is a type of blood and bone marrow cancer that produces too many white blood cells called lymphoblasts. This disease is sometimes referred to as acute lymphoblastic or acute lymphoid leukemia. The disease is termed “acute” because it progresses quickly, and if it is left untreated, it may be fatal within weeks.

ALL is the most prevalent leukemia in children, and the most common childhood cancer. ALL also occurs in adults. Of the 5,400 estimated cases of ALL that were diagnosed in 2008, about 30 percent were adults. The causes of ALL are unknown.
