“Good Morning America" anchor ROBIN ROBERTS just announced she was just diagnosed with a serious blood and bone marrow disease after beating breast cancer.

The feisty 51 year old GMA fan fave who beat breast cancer previouisly said she’s determined to beat this as well.


An emotional Roberts —  surrounded by her co-hosts, as well as World News Tonight anchor and close friend Diane Sawyer — made the announcement towards the end of Monday’s broadcast and then issued a blog post.

In a statement Robin said, "Today, I want to let you know that I’ve been diagnosed with MDS or myelodysplastic syndrome.  It's a disease of the blood and bone marrow and was once known as preleukemia.

"As many of you know, 5 years ago I beat breast cancer.  I’ve always been a fighter, and with all of your prayers and support, a winner. Sometimes the treatment for cancer can cause other serious medical problems."

"My doctors tell me I'm going to beat this — and I know it's true."

Roberts will begin pre-treatment starting today — chemotherapy in advance of a bone marrow transplant operation to occur later this year.
