The 38-year-old told Sports Illustrated's MMQB in a new interview that she underwent surgery at Cedars-Sinai Medical Center in Los Angeles on Oct. 11.
"Should I have been standing for a full game five days after surgery? Let’s just say the doctor didn’t recommend that," Andrews told SI. "But just as I felt during my trial, sports were my escape. I needed to be with my crew."
Andrews went through a second procedure on Nov. 1 and was later told she wouldn't need radiation or chemotherapy.
The cancer battle came toward the end of an emotional year for Andrews. In March, she was awarded $55 million in her civil lawsuit against a stalker and a hotel owner over a secret recording and release of a video showing her naked during a hotel stay.
"Throughout my career, all I’ve ever wanted is to just fit in," Andrews told Sports Illustrated. "That I had this extra baggage with the scandal, I didn’t want to be any different. I felt that way about being sick too. I don’t want players or coaches to look at me differently."
She ended the year on a happier note. Last month, Andrews got engaged to her longtime boyfriend, hockey player Jarret Stoll.
