Giuliana Rancic to have double mastectomy

Television personality Giuliana DePandi Rancic.

(WJLA, AP) Six weeks after revealing she has breast cancer, E! News host Giuliana Rancic says she will have a double mastectomy.

The 37-year-old made the announcement Monday on NBC's "Today" show.

When Rancic was first told a mastectomy was an option, she said absolutely not.{ }But after consideration, she changed her mind, making a decision that she says will save her life and her chances of one day having a baby.

"It was not an easy decision but it was the best decision for me," she said.

She says choosing the surgery is about choosing to live without wondering when or if the disease will come back.

"For me it was just very important to get the cancer out," Rancic said. "That's what I wanted."

Rancic was originally hoping surgery and radiation would be all the treatment she needed. But speaking out Monday morning, she said she's at peace with the choice to take a radical approach to getting rid of the cancer.

She plans to have the surgery next week and said she hopes to be recovered by New Year's Eve, when she and husband Bill Rancic are planning to be in Times Square.

Dr. Marc Boisvert, medical director at the Center for Breast Health at Washington Hospital Center, says the surgery does lower the recurrence rate. Boisvert is not treating Rancic.

Boisvert says procedure and reconstructive techniques have changed dramatically over the last two decades, leading more women to choose this option when fighting the battle.

"What I tell my patients is if you're going to worry about this everyday, consider getting a partial mastectomy," Boisvert said.

Rancic said she received an "overwhelming outpouring of love, prayers and support" after announcing her breast cancer diagnosis in October.

"I want to make sure to thank everyone and give them an update for being so kind and loving and supportive," she said Monday.

E! expressed its support for Rancic in a statement Monday.

"Giuliana's strength continues to amaze us," the network said. "We admire her courage and are proud to stand by her side through every step on her path to full recovery."
