Leukemia is a cancer that starts in the blood-forming cells of the bone marrow. When one of these cells changes and becomes a leukemia cell, it no longer matures normally. Often, it divides to make new cells faster than normal. Leukemia cells also don't die when they should.
Leukemia is a malignancy (cancer) of blood cells. In leukemia, abnormal blood cells are produced in the bone marrow. Usually, leukemia involves the production of abnormal white blood cells -- the cells responsible for fighting infection. Acute lymphocytic leukemia (ALL, also known as acute lymphoblastic leukemia) is the most common type of leukemia in children, but it can also affect adults. 2  In this type of leukemia, immature lymphoid cells grow rapidly in the blood.
