If you and your doctor are considering a bone marrow transplant (BMT) as a treatment option, your doctor will first determine what type of bone marrow transplant is best for your specific case. If you need an autologous transplant, your transplant will be done with your own cells. If you need an allogeneic transplant, donated cells will come from an adult donor or umbilical cord blood unit. Remember, you are not responsible for finding your own donor.

For patients who need an allogeneic transplant, your doctor will look for a matching donor in your family. Each brother and sister who has the same parents as you has a 25% (1 in 4) chance of matching you. 

However, 70% of patients (7 of 10) do not have a match in their family. For these patients, doctors work together with Be The Match® to search the Be The Match Registry® and other registries around the world to find a matching unrelated donor or cord blood unit.
