Bone marrow donation risks
Bone marrow donation is a relatively safe procedure and carries no risks other than those related to the setting of the procedure itself. In case of bone marrow donation from the marrow itself, the main risk is that of the anesthesia, and the small wound found at the back of your pelvis will be no more than a few centimeters across.
Peripheral bone marrow donation is much safer and carries minimal risks. The choice of the type of donation, however, depends on the amount needed and the resources available at the hospital to obtain enough blood stem cells from the peripheral blood.
