This registry is for healthy people who are willing to donate their bone marrow to lymphoma and leukemia suffers if they are a match. Sufferers will be registered by their physicians, who will then keep a lookout for potential matches. For anyone to sign up to be a donor, all that is required is a simple mouth swab that is sent to you. You can register online easily and have the kit sent to your home. From there, you will follow the instructions, send it back, and wait to be called if a match is found. One person for every 480 registrants is a match, and has the opportunity to save a life.
