E! News host Giuliana Rancic, 37, made a shocking announcement this morning on "Today": She's been diagnosed with breast cancer.

"Through my attempt to get pregnant for the third time, we sadly found out that I have early stages of breast cancer," she revealed.

"It's been a shock. A lot of people have been asking, we saw that you went and got IVF, are you pregnant? But sadly, we've had to put that off," she says, saying that she found it early and will be going in for surgery later this week.

"I'm not gonna give up," she added about having a baby. "That baby will have saved my life ... there's some master plan. Now I know that [God] was looking out for me."
