Good Morning America co-anchor Robin Roberts to receive bone marrow transplant Thursday

CLEVELAND - Good Morning America co-anchor Robin Roberts will receive a bone marrow transplant today from her sister, Sally-Ann.

The GMA host is battling Myelodysplastic Syndrome or MDS.  This is a rare blood disorder that affects the bone marrow and usually arises on its own. However, on occasion it can occur as a result of cancer treatment as it did as a result of Robin’s successful breast cancer treatment.

For the past several months Robin has been undergoing chemotherapy in preparation for the bone marrow transplant.
