Robin Roberts was back on the set of "Good Morning America" Thursday, if only backstage.
Roberts, who is nearing the end of her recovery from her bone marrow transplant, is doing a series of "dry runs" that her doctors approved leading to her return to the 'GMA' anchor desk.
Roberts arrived to the studio in Times Square at 5 a.m. after getting up at 3:45 a.m.
"My doctors want me to see how many people I actually come in contact with. How my body reacts to the stimulation, that's code word for stress, of being in the studio environment," Roberts explained.
"My skin is very sensitive and so we have to see how it reacts to the studio lights. My vision is still a little blurry from the treatment. All of this is getting better day by day so that is the next step."
Roberts, a breast cancer survivor, underwent her bone marrow transplant in September to treat myelodysplastic syndrome or MDS, a rare blood disorder that affects the bone marrow.
Roberts is expected back on the anchor desk in a few weeks.
