Bone Marrow Donors Soar After GMA's Robin Roberts MDS Announcement

As many of you know, 5 years ago I beat breast cancer. I've always been a fighter, and with all of your prayers and support, a winner. Sometimes the treatment for cancer can cause other serious medical problems. Today, I want to let you know that I've been diagnosed with MDS or myelodysplastic syndrome. It's a disease of the blood and bone marrow and was once known as preleukemia. My doctors tell me I'm going to beat this -- and I know it's true. If you Google MDS, you may find some scary stuff, including statistics that my doctors insist don't apply to me. They say I'm younger and fitter than most people who confront this disease and will be cured. Today, I will start what is known as pre-treatment --- chemotherapy in advance of a bone marrow transplant later this year. Bone marrow donors are scarce and particularly for African-American women. I am very fortunate to have a sister who is an excellent match, and this greatly improves my chances for a cure. As you know from my recent interview with Mark Zuckerberg, organ donation is vitally important. Many people don't realize they can be bone marrow donors. I encourage everyone to sign up on a donor registry like bethematch.org. For more on this story: http://abcnews.go.com/Health/robin-ro...
