A Need for Donors
The likelihood of an ethnic minority patient finding a bone marrow donor are extremely low; significantly lower than that of Caucasian patients.

There are several reasons:
Bone marrow is the part of the body which produces the blood. Blood is made up of four main components: red blood cells, white blood cells, platelets and plasma. Each of these components serve an important function in the operation of the human body:
When someone's bone marrow becomes defective in some way, the body is unable to create normal blood cells. Based on the roles of the various blood components above, this poses very severe health risks, including an inability to transport oxygen, an inability to stop bleeding, and an inability to fight infection. Depending on the specifics of the diagnosis, patients undergo a variety of procedures, which can include chemotherapy.
When a patient's bone marrow is unresponsive to alternative measures, that means the bone marrow must be replaced. Humans are capable of receiving and growing bone marrow from others via transplant, which opens the door for the National Bone Marrow Registry and bone marrow donors.
The matching required for a bone marrow transplant is much more specific than the matching required between blood transfusion recipients. In order to receive a bone marrow transplant from another individual, a donor and recipient must have matching human leukocyte antigen (HLA) tissue types. HLAs are protein markers that the immune system uses to recognize which cells belong in the body and which do not. To minimize the chances of a transplant rejection, these HLA tissue types must match as closely as possible. (Source: marrow.org)
