Leukemia starts in the bone marrow where blood cells are made. It happens when certain blood cells divide without control or order. The abnormal cells crowd out the healthy blood cells. This causes many of the symptoms.
The cause of leukemia is not clear. It is likely a combination of genes and environment.
