marrow transplant

A marrow transplant, also called a stem cell transplant, is a medical procedure that replaces damaged or diseased bone marrow—the soft tissue inside bones responsible for making blood cells—with healthy stem cells. These stem cells can come from the patient (autologous) or a donor (allogeneic). The process typically involves preparing the patient with high-dose chemotherapy or radiation to destroy unhealthy cells, then infusing the healthy stem cells into their bloodstream. Once transplanted, these cells find their way to the bone marrow, where they begin producing new, healthy blood cells, helping treat conditions like leukemia, lymphoma, or certain blood disorders.
