What is bone marrow transplant? A bone marrow transplant is a medical procedure used to replace damaged or diseased bone marrow with healthy stem cells to restore normal blood cell production. Also known as hematopoietic stem cell transplant (HSCT), it helps treat conditions affecting red blood cells, white blood cells, and platelets. The procedure may involve autologous, allogeneic, or cord blood stem cells depending on the patient’s condition. At Medicover Hospitals, bone marrow transplant procedures are performed by experienced hematology specialists using advanced transplant protocols and supportive care systems.
