Leukemia
Leukemia is cancer of the blood. It’s the most common form of cancer in childhood. The cancer cells grow in the bone marrow and go into the blood. The bone marrow is the soft, spongy center of some bones. It makes blood cells. When a child has leukemia, the bone marrow makes abnormal blood cells that don’t mature. The abnormal cells are usually white blood cells (leukocytes). The bone marrow also makes fewer healthy cells. The abnormal cells reproduce very quickly. They don’t work the same as healthy cells.
Some of the types of leukemia that occur in children include:
- Acute lymphocytic (lymphoblastic) leukemia (ALL). This is the most common type of leukemia in children.
- Acute myelogenous (myeloid, myelocytic, non-lymphocytic) leukemia (AML). This is the second most common type of leukemia in children.
- Hybrid or mixed lineage leukemia. This type is rare. It is a mix of ALL and AML.
- Chronic myelogenous leukemia (CML). This type is also rare in children.
- Chronic lymphocytic leukemia (CLL). This type is extremely rare in children.
- Juvenile myelomonocytic leukemia (JMML). This is a rare type of cancer that doesn’t grow quickly (acute) or slowly (chronic).
