The 'Good Morning America' host Robin Roberts highlighted the urgent need for stem cell donations — an outpatient process that saved her life — on the 12-year anniversary of her return to 'GMA' following a stem cell transplant.

"Good Morning America" co-anchor Robin Roberts is marking 12 years since she returned to the anchor desk after receiving a lifesaving stem cell transplant.

Robin Roberts took to the air on the latest iteration of Good Morning America to look back on an emotional milestone — her return to the show after a stem cell transplant. Back in 2012, Robin, 64, was diagnosed with myelodysplastic syndrome, or MDS, a rare blood disorder that affects the bone marrow.

As "GMA" turns 50, we honor 12 years since the co-anchor's return to the desk after her stem cell transplant. Noise-canceling AirPods are a rare $149 and a bestselling Henckels 20-piece knife set is a record-low 65% off, to name a few.

Instead of Robin Roberts, Michael Strahan, and George Stephanopoulos, three replacements were at the GMA desk. They included familiar faces, Gio Benitez, Rebecca Jarvis, and Linsey Davis, who filled in admirably.
