Bruce Springsteen Shares Positive Health Update On Wife Patti Scialfa

Last month, Bruce Springsteen 's wife, Patti Scialfa , revealed that she had been diagnosed with cancer — multiple myeloma to be exact, which is a type of cancer that affects the bones and bone marrow. But, in a first look at upcoming ABC News special "Backstage and Backstreets," set to air on Sunday, September 20th, Springsteen shared an optimistic update on his wife.

Speaking to ABC's George Stephanopoulos, Bruce said of his wife when asked how she was doing, "She's doing good, we caught it early, which is important," adding, "It's a tough disease, it's very fatiguing."

As for why they chose now to reveal Patti's diagnosis, Springsteen said of the decision,"She hadn't played in the band in a long time, and people, I don't think, knew why. 'Where's Patti?'"

Scialfa shared her cancer diagnosis in early September in the new documentary, Road Diary: Bruce Springsteen and the E Street Band . She shared, "This affects my immune system, so I have to be careful what I choose to do and where I choose to go." She added, "Every once in a while, I come to a show or two and I can sing a few songs on stage, and that’s been a treat. That's the new normal for me right now, and I’m OK with that."
