Transcript for Cancer Survivor Meets Life-Saving Donor on 'GMA'
You're going to meet this wonderful woman right here because we have a lot in common. Many of you know I have a rare blood disease. It has a long name to it. Its nickname is mds. I'm going to undergo a bone marrow transplant in a few weeks now. I'm one of thousands of patients that need a transplant. In a perfect world, we all would be matched up with donors. I'm blessed that my sister is one. The happy ending of the story of the woman sitting next to me right now, I cannot wait. And you're going to meet the young man who gave you the gift of life. Before we have that reunion, erica, we want to show people your story. Thanks. Reporter: For erica turner, life as a happily-married mother of two came to a screeching halt. Her world stopped with a simple statement from her doctor. He said, mrs. Turner, we believe you have leukemia. And I looked at him and said, cancer of the blood? It was like somebody hit me with a low blow. Reporter: And her condition was spiraling. She was getting sicker. It's a very aggressive leukemia. Reporter: Even with chemo and radiation, there was only one life-saving solution. I had to have a bone marrow transplant. That was my only option to survive. Reporter: Erika was an inspiration to her medical team. She was filled with hope. Filled with love. And filled with joy. Reporter: A very tough battle. For african-americans and other minorities, it's harder to find a bone marrow match. The likelihood of finding an african-american donor is about 60%. A little higheor hispanics. It's about 70%. And for caucasians, it's in the realm of 90%. After weeks of waiting, as erika's condition worsened, a match. Even better news. They were a perfect match. Reporter: The zeros on the bottom say their blood proteins are no different. They're an absolutely perfect match. A ten for ten, they call it. It was a male. And that he was a senior in college. That's all I knew. Reporter: But when final preparations came for her transplant, erika was about to give up. I was burned out. I was tired. I didn't want to go. I fought and I fought. I tried. And my husband said, fine. Get back in bed. And we'll watch you die. I jumped up. I said, I'm going to die? Ha. I'm going to show you. Reporter: The transplant worked. And soon, erika was in remission. But there is one more stop on erika's journey. I've never met him. I've never seen him. But I'm so excited to look into his eyes. To look into his soul. And tell him thank you. I just want him to know, that he is my hero. When people are faced with the realization they might die and they have to rely on the kindness of a total stranger, and they say yes, and everything comes together, it's a pretty miraculous story. And it's a journey. If this doesn't give you goosebumps, I don't know what will. I am. I know you are. Are you ready to meet this young man? I'm ready to meet the man who saved my life. It gives us great pleasure to bring out christopher magoon, the young man who saved erika's life. Thank you. Thank you. Good to meet you, finally. You are great. Thank you. Bless you. Very nice to meet you. You are an angel. Thank you. You've been waiting to look into his eyes. You hadn't seen him before. You have to -- you're required to wait a year until you contact your donor. You've been doing facebooking back and forth? More e-mailing. More e-mailing, yeah. A bit of facebooking. What is this, you have been waiting to look into his eyes and tell him? Christopher, I just want to say thank you, from the bottom of my heart, with my whole soul and my whole being. Thank you for giving me back to my parents. Thank you for giving me back to my kids and to my husband. I love you. And there's nothing in this world that I would not do for you because you did it for me. And I love you. I love you. Thank you so much. I love you. You're beautiful. We've been calling you a hero. And we were really touched when you said that this woman right here is. Absolutely. What do you mean by that? You're the one that fought for your family. I had the easy job. You know, I was asleep for the whole thing. I got to watch tv for two days. That was it. You know, you're the one who is sick. Yes. And always believed you were going to get better. Yes. And you did. I did. And now, youan supply hope for people in similar situations across the country. Yes. But there's people like you that give us life. You know, donations -- this has to be even more precious, erika, that a total stranger -- my sister -- my momma made my sister give me her marrow. My whole family wanted to do it. And it was just a blessing. It's not that common. But a total stranger. Yes. And you're right. Your sister, she loves you. She's seen you grow into the beautiful woman that you are today. This young man here, he didn't know me from a can of paint, you know? He didn't know me. And he was so willing and I just can't find the words. But he was just so willing to give his life, you know? So that I can have mine. Christopher, what would you say to those people who are wondering whether or not they should join the registry? I would say do it again in a second. Even if you don't know anyone who is sick, you might later down the line. It's really not that painful a procedure. That's one of the huge myths. Trust me, it's not that bad. It's like getting your wisdom teeth out. You're under. You wake up. People take really good care of you because you're doing a good thing. Go to bethematch.Com. And get that cheek swab. A painless procedure to get in the registry. That's the most important step. It is. We're going to let you spend more time together. Erika, you have your husband and your beautiful boys here. Christopher, bless your heart. Thank you so very much.
