The news was announced on "GMA" this morning, with Josh Elliott adding that she'll slowly work up to anchoring the newscast 5 days a week.

"What a difference a year makes," said Roberts, who began feeling the symptoms of her illness about a year ago. "I cannot wait to return to my "GMA" family. It's going to be an incredible morning in Times Square. The overwhelming thoughts and prayers of the viewers have played a major part in getting me here today. I cannot thank everyone enough."

Roberts announced last June that she had been diagnosed with the rare blood and bone marrow disorder Myelodysplastic syndrome (MDS) after successfully fighting breast cancer while her treatment and triumphs have been well-documented by the "GMA" crew over the ensuing months.
