A stem cell transplant is a treatment to replace your diseased bone marrow with healthy stem cells that help you grow new bone marrow. A stem cell transplant may be an option if Hodgkin's lymphoma returns despite treatment.
During a stem cell transplant, your own blood stem cells are removed, frozen and stored for later use. Next you receive high-dose chemotherapy and radiation therapy to destroy cancerous cells in your body. Finally your stem cells are thawed and injected into your body through your veins. The stem cells help build healthy bone marrow.
