Bone marrow transplant survivors have an increased risk of developing a second or “secondary” cancer later in life. This video discusses risk factors for developing a secondary cancer, cancers most frequently seen after transplant and monitoring and testing that should be done periodically to catch second cancers early when they are easiest to treat. (Throughout the talk, bone marrow transplant refers both to bone marrow transplants and stem cell transplants, as well as cord blood transplants.)
