E! presenter and reality TV star Giuliana Rancic, who has been battling breast cancer, announced on Today Monday morning that she will undergo a double mastectomy.

Appearing with her husband Bill Rancic, the 37-year old explained how she came to the decision to get the surgery, instead of going with other measures that wouldn't require the removal of her breasts.

"With a double mastectomy, I have less than a one percent chance of getting it back," Rancic told TODAY. "With another lumpectomy, radiation and medication, I could have a 20, 30 or 40 percent chance in my lifetime. In the end, it all came down to choosing to live and not looking over my shoulder the rest of my life."

Watch Giuliana and Bill talk about the gut-wrenching decision below.
