What is bone marrow?
Bone marrow produces blood cells for the body. The blood-forming cells in bone marrow grow into:
Red blood cells, which carry oxygen to all parts of the body
White blood cells, which help the body fight infection
Platelets, which help control bleeding
A healthy body is always making new blood-forming cells, which are necessary for survival. If the blood-forming cells begin making many abnormal cells and not enough healthy blood cells, as happens in leukemia, a marrow transplant to replace the blood-forming cells may be the best treatment.
What diseases are treated with a marrow transplant?
A bone marrow transplant is a standard treatment option for many patients with life-threatening diseases like leukemia or lymphoma, which are cancers of the blood.
