Christina Applegate opens up about her recent battle with breast cancer and the radical decision to undergo a double mastectomy on Tuesday’s Oprah.

Christina admits she secretly suspected she’d be diagnosed with cancer at some point because her mother is a two-time breast cancer survivor.

“There was this part of me that sort of knew that the other shoe was gonna drop,” the star of ABC’s Samantha Who? tells Oprah.

“I was just gonna let them (breasts) go… and then, when I met with my doctor and I told him that was my decision and he brought the surgeon in, it was like the floodgates just opened up and I lost it.”
