Giuliana Rancic revealed today that she has breast cancer, after doctors discovered a tumor during her latest round of in-vitro fertilization.

“It’s been a shock,” the 36-year-old E! News and Style Network host said in an emotional interview with the “Today” show. “A lot of people have been asking, ‘We saw that you went and got IVF, so what happened? Are you pregnant?’ But sadly, we’ve had to put that off.”

Having caught the cancer in its early stage, she said her prognosis is good.

“I will be OK, because I found it early,” Rancic said. “Now I truly believe God was looking out for me.”

Rancic had planned to wait until she was 40 to have a mammogram but said her IVF doctor strongly encouraged her to get one before undergoing fertility treatment because pregnancy can accelerate the spread of any potential cancer.

The cable host has long documented her struggle to have a baby on her Style Network reality-TV show “Giuliana and Bill” with husband Bill Rancic, the first “Apprentice” winner. At the end of last season, the pair were going for their third round of IVF after the first ended in a miscarriage and the second failed to work.

Rancic says she will still push to have a baby after undergoing cancer treatment.

“I still want this baby … because this baby has saved my life,” she said. “If I had gotten pregnant later down the line, I could have been a lot sicker.”

Her property developer husband has been “unbelievable,” she said. “The best thing about Bill is, he lets me cry when I want to cry.”
