In an autologous BMT, the type needed for your disease, you are your own donor. The advantages of autologous BMT are elimination of the danger of GVHD and the possibility of an easier recovery period.
In an autologous BMT, your own bone marrow and/or stem cells will be removed before you receive chemotherapy and/or radiation. After it has been removed, your bone marrow may need to be processed to remove lingering cancer cells or isolate stem cells. It will be frozen and stored until your treatment is finished, then thawed and given back to you to replace the marrow that was destroyed by your treatment.
Autologous BMT is possible when the disease affecting your bone marrow is in remission or the condition the patient is being treated for does not involve the bone marrow.
