What is Bone Marrow Transplant?

Bone Marrow Transplant

Quick Answer

A bone marrow transplant is a medical procedure that replaces damaged or destroyed bone marrow with healthy bone marrow. It is often used to treat certain types of cancer, blood disorders, and immune system conditions.

Overview

Bone marrow is the soft tissue inside bones that produces blood cells. When bone marrow is damaged due to diseases like leukemia or conditions such as severe anemia, a transplant can help restore its function. During a bone marrow transplant, healthy marrow from a donor is infused into the patient's bloodstream, where it travels to the bone cavities and begins to produce new blood cells. The process involves several steps, starting with the collection of healthy bone marrow from a donor, which can be a matched relative or an unrelated volunteer. Before the transplant, the patient usually undergoes chemotherapy or radiation to eliminate any remaining diseased cells and prepare their body for the new marrow. This procedure is critical because it can save lives by providing a fresh supply of healthy blood cells, which are essential for fighting infections and carrying oxygen throughout the body. An example of when a bone marrow transplant is necessary is in the case of a child with leukemia. After undergoing treatment to destroy cancer cells, the child's bone marrow may not be able to recover on its own. A transplant can provide the child with healthy cells, giving them a better chance at recovery and a healthy life, illustrating the importance of this surgical procedure in modern medicine.
