It is a method used to restore the body's ability to produce new blood cells after a patient has undergone other forms of aggressive cancer treatment [5]. For certain types of cancer, very high doses of chemotherapy or radiation are required to destroy the cancer cells, but cells that produce blood are also destroyed in the process. In this case, stem cells are administered along with a blood transfusion. Stem cells are collected either from the patient before cancer treatment or from a donor. After stem cell treatment, it takes two to four weeks for an individual's body to recover and begin producing blood cells again. As with other treatments, there are risks involved, including the possibility that the stem cells will not settle in the bone marrow and begin producing blood cells as intended. When that occurs, it is deemed a failed treatment, and the process may be repeated.
