"NFL on FOX" star Erin Andrews has revealed she battled cervical cancer during the regular season -- which required multiple surgeries -- but she didn't miss a single game.
The good news -- Andrews says she's "cancer-free" now ... and plans on working the Super Bowl.
The 38-year-old sideline reporter broke the news to MMQB ... saying she was diagnosed back in Sept. but told doctors she didn't want to miss any work.
She ended up missing two taping of "Dancing with the Stars" before her first surgery in October.
