NEW YORK >> ABC’s “Good Morning America” co-host Robin Roberts is already wishing to leave the hospital following her bone marrow transplant.

Her oncologist, Dr. Gail Ropoz, said on the morning show that Roberts had emailed that note Friday, a day after the procedure. ABC showed a brief video clip of Roberts in her hospital bed receiving bone marrow from her donor sister to treat MDS, a blood and bone marrow disease.

Ropoz said Roberts is being monitored to guard against infection and to see that her white blood cell count is increasing. She said Roberts can expect some good and bad days in her recovery.

She was surrounded by family and friends during the five-minute procedure, including ABC anchor Diane Sawyer.
