Maura Tierney told the world back in July that she was going to undergo surgery to remove a tumor in her breast. At that time the plan was that she would have the surgery and return to the show Parenthood which had just started shooting. Now though, she is being forced to drop out of the show because her treatments are going to interfere with the production schedule.
Her spokesperson told The Hollywood Reporter that Maura is disappointed she can't be on the show and that "her doctors remain confident that the outcome of her treatments will be positive."
I really hope so because Maura is one of my all time favorite people and actresses.
