How likely is having a relapse during a bone marrow transplant?

Most are successful: This will depend on the reason for the transplant and the exact type of transplant performed. For example, an identical twin bone marrow will not reject and some blood cell cancers have a greater chance of recurring than others. Check with your hematologist-oncologist.

Depends: The chance of having a relapse after a bone marrow transplant is dependent on the disease that a patient is being transplanted for, the status of the disease and the type of transplant.
