Giuliana Rancic feels "very honoured" to be seen as a role model following her cancer diagnosis.

The 37-year-old television host was diagnosed with breast cancer last year and underwent a double mastectomy. Giuliana and her businessman husband Bill Rancic opened up their lives to the public through their reality show, which the star is so glad she did.

"No way!" she exclaimed to the UK edition of OK! magazine when asked if he ever thought she'd be the role model she's become. "My biggest dream was to do exactly what I'm doing. I really do believe God has this master plan for me. He gave me this job so that I can help others.

"If I could go back and erase the day I was diagnosed, I would - it's ugly - but if you're going to go through it, make the best of it and try to make a difference.

"So many use reality shows to sell and put bad thought in young women's minds. We're very honoured we've been able to use our reality show for good."

Giuliana has previously spoken about how lucky she is to have her loved ones around her.

"[Mine and Bill's] marriage has gotten even stronger this year," she revealed. "I have an amazing husband, a wonderful family. I am very lucky."
