Save 100's of thousands district wide on textbooks!! Districts of all sizes a re searching for what to purchase and provide for their teachers.

Leukemia: Causes, Symptoms and Treatments. Leukemia (British spelling: leukaemia ) is cancer of the blood or bone marrow (which produces blood cells). A person who has leukemia suffers from an abnormal production of blood cells, generally leukocytes (white blood cells). People sometimes confuse leukemia and lymphoma. Leukemia is a cancer of the blood, lymphoma is cancer of the lymphatic system (lymph glands). The word Leukemia comes from the Greek leukos which means white and aima which means blood. The DNA of immature blood cells, mainly white cells, becomes damaged in some way.
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.hronic lymphocytic leukemia (CLL) is a type of cancer that starts from cells that become certain white blood cells (called lymphocytes) in the bone marrow.
