Autologous Transplant is stem cell transplant that uses your own cells, which means you are your own donor. In this type of transplant, your stem cells are harvested (removed) prior to receiving high doses of radiation therapy, or chemotherapy, or both. Your stem cells are then frozen and stored. After you receive your high dose cancer treatment to remove cancerous cells from your marrow, your stem cells are then thawed and returned back into you. This is known as “rescue” transplant.
