Robin Roberts returned to the set of Good Morning America yesterday morning for the first time since her bone marrow transplant this past September.

The popular television host was diagnosed last year with MDS (myelodysplastic syndrome), a rare blood disorder that affects bone marrow. Roberts discovered that her sister was a perfect bone marrow match during the course of her treatment.

“What a thrill to be back at GMA’s Times Square studio this morning and see the best folks in the world, my GMA family,” Roberts announced.

Although she did not resume her usual duties as a morning co-host that day, she returned to the studio before the show began to start the slow process of transitioning back to work, which included testing out the bright studio lights, getting used to wearing makeup again, and assessing the risk of infection on set.
