Bone Marrow Transplant
A treatment that restores healthy blood-forming stem cells after the bone marrow has been affected by disease or intensive treatment.
What Is Bone Marrow Transplant?
A bone marrow transplant is a procedure that replaces damaged or destroyed blood-forming stem cells with healthy ones. It is also called a stem cell transplant or hematopoietic stem cell transplant.
This treatment may be used for selected blood cancers and bone marrow-related conditions, such as leukemia, lymphoma, multiple myeloma, and some other disorders.
American Cancer Society explains that a stem cell transplant puts healthy blood stem cells back into the body after bone marrow has been destroyed by disease, chemotherapy, or radiation.

How Bone Marrow Transplant Works
The process usually includes:
Pre-transplant assessment
Chemotherapy or conditioning treatment
Stem cell infusion
Blood cell recovery
Infection monitoring
Long-term follow-up
Types of Transplant
Autologous Transplant
Uses patient’s own stem cells
Uses the patient’s own stem cells, which are collected before treatment and returned after high-dose chemotherapy or conditioning treatment.
Allogeneic Transplant
Uses donor stem cells
Uses stem cells from a donor. This type of transplant may be considered when donor cells are needed to help rebuild healthy blood-forming cells.
Matched Sibling Donor
Sibling donor match
A type of allogeneic transplant where the donor is a sibling whose tissue type is closely matched to the patient.
Unrelated Donor
Registry donor option
A donor is identified through a donor registry when a matched sibling donor is not available. Suitability depends on medical assessment and matching results.
Cord Blood Transplant
Umbilical cord blood stem cells
Uses stem cells collected from umbilical cord blood. This may be considered in selected cases depending on disease type, cell dose, and transplant planning.
Who May Need It?
Bone marrow transplant may be considered for selected patients with:
Leukemia
Lymphoma
Multiple myeloma
Bone marrow failure disorders
Certain high-risk blood diseases
Recurrent or difficult-to-control blood cancers
Not all patients with these conditions need a transplant.

Common questions about bone marrow transplant
Is bone marrow transplant the same as stem cell transplant?
They are closely related terms. Many modern transplants use stem cells collected from blood.
Do all patients need a donor?
No. Autologous transplant uses the patient’s own stem cells. Allogeneic transplant needs a donor.
How long is recovery?
Recovery may take weeks to months, and immune recovery may take longer.
Is transplant suitable for older patients?
It depends on overall health, organ function and transplant center assessment.
