Bone marrow transplant and organ transplant are completely different things. But both are transplants that save the lives of seriously ill people.
Vadim Matveevich Kemaykin, Head of the Oncohematological Service of the National Scientific Research Center: "Bone marrow transplantation is not done for everyone and not always. The disease is the same, but the degree of risk that it will return is different. Doctors see it. If the risk is low, the likelihood of relapse is small. Transplantation, especially if not A relative donor, you can not do it. Medium, and God forbid, tall - you need to ring all the bells and look for a person whose stem cells are most suitable for transplantation. Without it, the patient will not live long. But finding a donor is not easy!
Even one suitable unrelated donor in the same country in which the patient lives is already a great success. "
