(NEW YORK) -- On Wednesday, Robin Roberts made her triumphant return to ABC's Good Morning America, five months after she underwent a bone marrow transplant to treat a rare blood disorder. The network will give us an inside look into her fight against myelodysplastic syndrome in a 20/20 special airing Friday night.
Robin's Journey, airing at 10 p.m. Eastern time, documents personal moments in Roberts' battle, including her pre-transplant treatment and her hospitalization. It will feature her ABC News colleagues Diane Sawyer, George Stephanopoulos, Sam Champion, Josh Elliott and Lara Spencer.
Roberts tells ABC News Radio she doesn't recall some of the moments in the special because she was "out of it" at the time. She adds that the program was tough for her to watch: "There were some parts I just had to zip through and say, I don't want to remember. But it's important to."
It's important, she says, because the special can serve as an educational tool for viewers and help them "be better aware" in the event someone in their life goes through a similar battle.
