Cancer is a phrase used to describe the abnormal proliferation of cells. In this case, cells proliferate uncontrollably in any portion of the body, causing a problem as they spread to other sections of the body. Leukemia occurs when cells develop out of control in the bone marrow. The bone marrow produces blood, and when cancer develops in the bone marrow, it affects the blood.Â
Bone marrow is a soft and spongy substance that is found in bones. Bone marrow produces a variety of cells, including red blood cells, which transport oxygen and nutrients, white blood cells, which aid in infection resistance, and platelets, which help in blood clotting.
