The stem cell transplant is a procedure to replace one's damaged bone marrow with healthy bone marrow. Before going through with this procedure, a person will receive high amounts of chemotherapy or radiation therapy to destroy the diseased bone marrow. Once through with this, the person will receive new blood-forming stem cells to help rebuild the bone marrow. Stem cells for the procedure may be donated or used from another part of the person's body.
