ABC’s Roberts has blood, bone marrow disorder

NEW YORK (AP) — Robin Roberts is facing a new medical challenge that will require her to start chemotherapy and get a bone marrow transplant. The “Good Morning America” anchor announced on the ABC show Monday morning that she has been diagnosed with myelodysplastic syndrome, a blood and bone marrow disease once known as preleukemia. She says she will undergo chemo and a bone marrow transplant this year as “pretreatment” for the disease, which she says she has known about for several weeks. She says her sister is a great match for her. While she says she’ll miss a day here and there, she’ll remain on the air. Roberts battled breast cancer five years ago.
