Robin Roberts: 'Good Morning America' anchor announces medical leave

Good Morning America anchor Robin Roberts will take a leave of absence from the show after this week, the show has confirmed. Shortly before this morning's broadcast, when Roberts made the announcement herself, this message appeared on GMA's official Twitter: "Friday will be @RobinRoberts' last day before leaving for her bone marrow transplant and treatment for MDS."

Roberts began to unravel the news this past weekend that her leave was impending when she tweeted about leaving her dog KJ with friends in Maine. This morning, Roberts told viewers that she is preparing to check into the hospital from treatments next Tuesday. "It still takes about 10 days after being admitted because there are some things you have to go through before the (bone marrow) transplant actually occurs," she said according to USA Today's report. Roberts' sister Sally will provide the bone marrow for the transplant. Roberts will be away from the program for months, though no specific return date has been announced.

Throughout the week, GMA will celebrate "Robin's journey." Roberts, a breast cancer survivor, announced in June that she was suffering from MDS (myelodysplastic syndrome), a rare blood and bone-marrow disease. She told viewers last month that she was anticipating a medical leave in late August, though she had not set a specific date until today's confirmation.
