Giuliana Rancic is having a double mastectomy next Tuesday and behind her strong and cheerful demeanor, she admitted exclusively to RadarOnline.com that she is "scared" about the surgery, but she adds, “I am going to survive.”

"I think I'm definitely scared of the unknown," Giuliana,37,said about her upcoming breast cancer surgery.  "I'm scared because I've never done this before, but I have Bill with me," she said about her husband who was with her at our interview at the SLS Hotel in Los Angeles Thursday.

The duo said they draw strength from each other, but that what really helps them is looking forward to the future without cancer.
