Question: what episode of grey's anatomy is izzie diagnosed with cancer

title: Izzie Stevens
text: However , in January 2012 , Heigl stated in an interview that she has asked the producers if she could return to the show to give closure to Izzie 's storyline : `` I 've told them I want to ( return ) , '' she said . `` I really , really , really want to see where ( Izzie ) is . I just want to know what happened to her and where she went and what she 's doing now . My idea is that she actually like figures it out , and finds some success and does really well in a different hospital . She was always floundering you know , and so she was always one step behind the eight ball and I want to see that girl take some power back . '' She later went on to say that she regrets leaving the show , `` Oh yeah , sometimes , yeah . You miss it . I miss my friends . It was a great work environment ... and it becomes a family . I spent six years together with these people every day ... you grow up together , in a way , '' and again commented on Izzie possibly returning to the show , `` I always felt that if they wanted me to come back and sort of wrap up that storyline ... I want them to know that I 'm down with it if they want me to , but I completely understand if it does n't necessarily work ... They 've got a lot of story lines going on there . '' But in March 2012 , Shonda Rhimes said that there are no plans at the moment for the character to return , `` I think it was really nice to hear her appreciating the show . At the same time we are on a track we have been planning . The idea of changing that track is not something we are interested in right now . '' Three years later , Rhimes said she has completely moved on from the idea of Izzie coming back , `` I 'm done with that story . I 've turned that idea over in my mind a thousand times and thought about how it would go . And I do n't think so . ''
