Robin Roberts on Getting Second 'Chance' at Life After Health Scare: 'I Had a Year or Two to Live'

Robin Roberts underwent a life-saving procedure in 2012. Now, she lives to tell the tale.

The Good Morning America anchor, 60, was previously diagnosed with myelodysplastic syndrome and needed a bone marrow transplant surgery to survive. Roberts' sister, Sally-Ann, eventually became her donor.

During an upcoming appearance on Rachael Ray Wednesday, Roberts opens up about how she felt upon learning that Sally-Ann was a match.

"My doctor told me I had a year or two to live if I didn't have a successful transplant," she recalls to Rachael Ray. "My other siblings were not a match. My doctors had already told me there was not anybody on the list that matched me. It came down to my sister Sally-Ann."

Roberts continues, "When they came back — and they had to do repeated tests to get to the certain level — and they said, 'Yes, she's a match.' And I cannot tell you, you just exhale, and you're like, 'I got a chance.' "

Roberts gets choked up as she remembers seeing whether her sister would be willing to be her donor.

"I remember calling my sister because then I had to say to her, 'You are a match. Do you want to go through with this,' " she recalls. "Because sometimes, people will put themselves on the list and say they want to be a donor, and then it gets to that point and they have second thoughts."

"And my sister said, 'Not only is this something I want to do, I feel I was born to be [your donor],' " she adds.

Roberts celebrated the ninth anniversary of her life-saving procedure on Instagram Monday, sharing a photo of herself holding up nine fingers as her dog sat in her lap.
