Actress Maura Tierney is returning to the small screen after finishing treatment for breast cancer.

The former ER star was forced to walk away from TV drama Rescue Me after she was diagnosed with the disease last year. But, now she's putting her cancer battle behind her as she gets back to work on the show as Denis Leary's love interest.
 
Her rep tells TVGuide.com, "(Tierney) has finished treatment and is doing very well and is happy to move forward with the next phase of her life."
 
The actress has already filmed scenes for the program, which will air next year.
