Robin Roberts and Good Morning America

Robin Roberts Taking Medical Leave from Good Morning America

Robin Roberts is ready to do battle.
On Monday, the 51-year-old Good Morning America co-anchor announced that her extended medical leave begins next Monday, Sept. 3; recently diagnosed with myelodysplastic syndrome (MDS), a rare blood and bone marrow disorder, Roberts is undergoing a bone marrow transplant in September, and she'll temporarily sign off this
Friday Aug. 31.

With an ongoing feature called "Robin's Journey," this week's GMA will put a spotlight on Roberts' treatment, procedure and recovering process, with her medical team weighing in her fight against MDS -- and other families who have dealt with the disease.
