Leukemia

Childhood leukemia is a cancer that starts in the blood-forming cells in the bone marrow. Leukemia is most often found in the white blood cells, but  it can develop in other blood cell types. It is the most common form of childhood cancer and there are several types and sub-types.

If your child has been diagnosed with leukemia, you can request a copy of ALSF's Childhood Leukemia to learn more about your child's cancer and treatment options, as well as read stories from other childhood cancer families.
