Giuliana Rancic has returned to her on-air job just two weeks after undergoing a double mastectomy and reconstructive surgery.

The 37-year-old television host had the operation as part of her on-going treatment for breast cancer.

Giuliana appreciates she has made a quick return but it wasn't without getting the go ahead from her physicians.

"It feels great to be back at work," she said. "I wasn't sure whether I was going to return to E! News this week or after the New Year. The last thing I wanted to do was rush my recovery.

"Thankfully, I've been feeling better every single day since surgery and this weekend my doctors gave me the green light to get back to work.

"Even though I moved a tad slower than usual today, everyone welcomed me back with open arms and it was a wonderful homecoming."

Giuliana chose to undergo the double mastectomy to drastically limit her chances of the cancer returning.

She is dedicating a lot of her time now to urging women of all ages to self-examine and go to their doctors if they notice anything unusual.
