Giuliana Rancic returned to "The Today Show" on Monday, December 5, to update viewers on health and announced that she will undergo a double mastectomy as part of her treatment for breast cancer.

The E! News host, who announced that she had early stages of breast cancer on October 5, appeared on the morning talk show with her husband when she said she decided to undergo the procedure after the lumpectomies she previously had did not effectively eliminate the cancer.

Her husband Bill Rancic, explained that the couple was going to a follow up appointment with her doctor when they learned the news.

"The next day we were going into the doctor hoping for some good news and unfortunately the one breast they weren't able to clear the margins and get all the cancer out," he said. "So we were then faced with a decision to make. Do you go back and do another lumpectomy and try to clean it out or do you go for another more radical procedure."

Giuliana Rancic also said that her desire to have child played "a big part" of her decision to get the double mastectomy but "not all of it."

"If I had chosen to just do another lumpectomy and then do radiation and then do anti-estrogen therapy, which means two to five years of medication, that basically puts me into early menopause," Giuliana Rancic said. "Then I would have to put off having a baby for several years. So that was something we took into account."

Giuliana married Bill Rancic, the winner of the first season of "The Apprentice," in 2007. The couple launched their own reality show, "Giuliana & Bill" in 2009.

She added, "To be honest, at the end all it came down to was just choosing to live and not looking over my shoulder for the rest of my life."

Bill Rancic said the two spoke with several experts and specialists before making the decision. "If she would have gone with the lumpectomy and radiation, then you have to go in every six months for the rest of your life getting mammograms," he said.

"Knowing Giuliana, she's going to be worrying three weeks before the mammogram, waiting for the results worrying and you're always looking over your shoulder," he added. "So I think in this particular case this was the best option for Giuliana."

"With the double mastectomy I have less than a 1 percent chance of getting it back," Giuliana Rancic said. "With another lumpectomy, radiation and medication, I could have seen 20 to 30 to 40 percent chance in my lifetime and for me it just wasn't worth it."

"I couldn't be more at peace with the decision. But it's hard, and I still break down some nights," Giuliana Rancic added. But I'm okay."
