Giuliana Rancic made a horrible announcement Monday on Today: “I have early stage breast cancer.”

The 37-year-old E! personality told Today host Ann Curry that her doctor discovered the illness back in August as she was about to begin IVF.

Before going through IVF, her doctor insisted that Rancic get a mammogram, an insistence which ended up saving her life.

Rancic said she “wasn’t prepared to get a mammogram until I was 40 years old.” The star who has had no history of breast cancer in her family said, “I never in my wildest dreams expected anything to be wrong.”

When Rancic heard the shocking news, she said she was “sobbing… It was like the world just crashed around me.”

But she says, “I will be okay, because I found it early. I’m doing surgery this coming week, and then I go to radiation for six and a half weeks.”

Her husband, Bill Rancic, has been extremely supportive during this ordeal. “Bill is unbelievable. He lets me cry when I want to cry.”

“He just lets me feel what I want to feel.”

And what about her pregnancy plans?  Giuliana says, “I’m not gonna give up. That baby will have saved my life.” She continued, “There’s some master plan. Now I know that [God] was looking out for me. I think a lot of us think we’re invincible. We have to start putting ourselves on the to do list.”

Celebrities and fans have shown their support for Giuliana and husband Bill took to Twitter to thank everyone:

“Thank you for all your love and support today. G is reading all your messages. She will win this fight, I PROMISE, and be back better than ever.”
