Robin Roberts will start medical leave from “Good Morning America” after the show’s broadcast on Friday.
The 51-year-old anchor revealed in June that she had been diagnosed with myelodysplastic syndrome (MDS), which was once known as preleukemia.
MDS is rare disease of the blood and bone marrow can be caused by the treatment for cancer. In 2008, Roberts battled breast cancer.
The former ESPN reporter will undergo chemotherapy and a bone marrow transplant. Her sister Sally was a match and will serve as her donor.
“Good Morning America” will pay tribute the former athlete in with a special segment called “Robin’s Journey.”
“I’ll begin the [transplant] process. It still takes about 10 days after being admitted because there are some things you have to go through before the (bone marrow) transplant actually occurs,” Roberts shared on air.
In the days after her initial announcement, Roberts wore fashionable armbands to cover the pic line chemotherapy treatment while on air.
On July 31, she left “GMA” mid-broadcast after announcing she wasn’t feeling well and went on an early vacation.
During her absence, ABC has lined up Barbara Walters, Diane Sawyer, Katie Couric and Kelly Ripa other celebrity guest hosts to sit alongside George Stephanopoulos, Lara Spencer, Sam Champion and Josh Elliott.
For the first time in 16 years, “GMA” has beaten NBC’s “Today” in the ratings numerous times since its initial victory on the week of April 9.
