“This affects my immune system, so I have to be careful what I choose to do and where I choose to go,” Scialfa, 71, said in the film when discussing her illness.

“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,” she continued.

Scialfa joined the E Street Band right before the 1984 “Born in the U.S.A.” tour. She later married Springsteen in 1991 and was inducted into the Rock and Roll Hall of Fame in 2014.

Fox News Digital reached out to Scialfa for comment.

What is multiple myeloma?
Multiple myeloma, a cancer of the cells in the bone marrow, is diagnosed in more than 35,000 people in the U.S. each year, according to the American Cancer Society.

Plasma cells grow in the bone marrow, which has been described as a “factory” of blood.

In a healthy person, the cells produce proteins called antibodies that are directed against germs to fight infection, according to Dr. Cristina Gasparetto, a hematologic oncologist and professor of medicine at Duke University School of Medicine.

Multiple myeloma occurs when plasma cells grow “out of control,” the ACS states.
