( PEOPLE.com ) -- Giuliana Rancic said Monday that she has breast cancer , having discovered a tumor during a mammogram while undergoing another round of in-vitro fertilization in an effort to get pregnant . The E ! News and Style Network host , 36 , made the emotional announcement on NBC 's `` Today '' show . She will undergo surgery this week and then have six weeks of radiation therapy . The cancer has been detected early , and the prognosis is good , she said . Rancic was going to wait until 40 to have a mammogram , but her IVF doctor suggested she have one now . She says she will still push to have a baby , following one IVF attempt that ended in a miscarriage and a second that did n't work . `` I still want this baby ... because this baby has saved my life , '' she said . `` I truly feel God was looking out after me ... If I had gotten pregnant later down the line , I could have been a lot sicker . '' She also says her husband , Bill Rancic , has been `` unbelievable . The best thing about Bill is , he lets me cry when I want to cry . '' Coincidentally , Rancic recently filmed some on-the-street interviews to bust breast-cancer myths for the non-profit Bright Pink as part of National Breast Cancer Awareness Month , which marks its 25th anniversary this year .
