Leukemia is a cancer of the blood cells. It starts in the bone marrow, the soft, spongy inner part of certain bones. The cancerous cells in leukemia are the white blood cells (leukocytes).
About 31,000 new cases of leukemia are diagnosed in the United States each year. Acute myelogenous leukemia and chronic lymphocytic leukemia are the most common types in adults.
