Why do a blood or marrow transplant (BMT)?

There are three reasons to do a BMT: • In the case of bone marrow failure, a BMT replaces absent or abnormal stem cells with functional stem cells allowing production of blood cells and a healthy immune system. • If the patient has cancer, the BMT replaces stem cells that are killed as a side effect of very high dose chemotherapy and radiation therapy given to cure the cancer. • When genetic errors are present, the BMT replaces defective or absent cells in the body that originate in the bone marrow.
