KidsHealth: Childhood Cancer - Leukemia
When a child has leukemia, large numbers of abnormal white blood cells are produced in the bone marrow. These abnormal white cells crowd the bone marrow and flood the bloodstream, but they cannot perform their proper role of protecting the body against disease because they are defective.

The Leukemia & Lymphoma Society is the world's largest voluntary health organization dedicated to funding blood cancer research, education, and patient services.

MedlinePlus: Childhood Leukemia
Leukemia is cancer of the white blood cells. It is the most common type of childhood cancer.
