Robin Roberts announces GMA leave, will undergo bone marrow transplant

NEW YORK

After undergoing 10 days of tests, Roberts will receive the transplant from her sister. Doctors say her sister is a perfect match for the transplant.

Roberts has MDS, a rare blood and bone marrow disease once known as preleukemia. She is also a breast cancer survivor.

Roberts said she is luckier than many workers who become ill, and noted her bosses have been generous in giving her time off. They've also assured her that her job will be waiting for her when she's well enough to return. She described herself as "very blessed."
