A bone marrow transplant is a medical procedure that replaces damaged or diseased bone marrow with healthy bone marrow. Bone marrow is the soft tissue inside bones that produces blood cells. This treatment is often used for conditions like leukemia, lymphoma, and certain blood disorders. There are two main types of bone marrow transplants: autologous, where a patient receives their own stem cells, and allogeneic, where the stem cells come from a donor. The procedure can help restore the body’s ability to produce healthy blood cells and improve overall health.
