What is acute lymphoblastic leukemia (ALL)?

ANSWER

ALL is a type of leukemia that starts from white blood cells in the bone marrow, the soft inner part of bones. It develops from cells called lymphocytes, a type of white blood cell central to the immune system, or from lymphoblasts, an immature type of lymphocyte.

Acute lymphoblastic leukemia invades the blood and can spread throughout the body to other organs, such as the liver, spleen, and lymph nodes. But it does not normally produce tumors as do many types of cancer. It is an acute type of leukemia, which means it can progress quickly. Without treatment, it can be fatal within a few months.
