Five months after recovering from a bone marrow transplant, Robin Roberts returned to Good Morning America (GMA)! The morning-show co-host has overcome breast cancer, and most recently a condition known as myelodysplastic syndrome (MDS). Few probably had ever heard of this condition, much less know what it is. MDS is a disorder where the bone marrow produces too few functioning red blood cells, white blood cells and platelets. Robin's treatment involved chemotherapy, a stem cell transplant and a long recovery.
