Please describe the types of stem cell transplants for treating cancer?

Two types: Only blood cancers can be treated with stem cell transplants. There are two sources for stem cells. Your own stem cells(if the bone marrow is healthy and uninvolved with cancer) or a matched donor stem cells. The stem cells can be colelcted from the bone marrow or from the peripheral blood(more modern technique).

HSC Transplant: The only stem cell transplant in regular practice are hematopoietic stem cell (HSC) transplants for diseases like leukemia, lymphoma and myeloma. HSC can be collected from donor bone marrow (BMT), from the peripheral blood (PBSC), or from umbilical cord blood. HSC transplants vary further by the type and intensity of the preparative chemotherapy, immune suppression, and selection of donor.
