Mel sits down with Acute Lymphoblastic Lymphoma childhood cancer survivor David Tuccaro. Bad to the Bone is David's biography, Bad to the Bone, written by Marala Scott, one of Oprah's Angel Network. David talks about his fight with ALL and most importantly how he was saved by a bone marrow donor. Registering to be a bone marrow donor is as simple as a cheek swab with a q-tip. Donating bone marrow is just like donating blood. David's bone marrow match was from Germany. Find out how a simple swab could save someone's life on an all new show available on demand.
