Former "Entertainment Tonight" correspondent Samantha Harris is battling breast cancer.

The 40-year-old television personality got choked up as she revealed the heartbreaking news on "Good Morning America" on Wednesday.

Harris initially detected a lump during a self-examination last fall, but her mammogram results came back clean earlier in the year. However, she says something still didn't feel right, which lead her to consult a breast cancer specialist several months later. Following a needle biopsy and a lumpectomy, specialists diagnosed her with breast cancer.

"It's scary and you worry. ... My daughters are three and six, you know. All they're concerned about is to have mommy active, be able to hold them, hug them, kiss them," a tearful Harris said. "I want to still do and from what the doctors say, I will still be able to do, but no matter how positive of a diagnosis as I have, it doesn't keep the demons of fear from taking over your mind and your thought process."

Harris consulted several specialists who presented her with two treatment options: A double mastectomy or a less-radical second lumpectomy with radiation. She opted for the double mastectomy and will go under the knife later this month, according to People.

Harris married Michael Hess in 2005 and the pair has two daughters, Josselyn Sydney, 6, and Hillary Madison, 3.

Despite her prognosis, the former "Dancing With the Stars" host is staying positive. "I will be here to plan my daughter's weddings and they better like the dress I pick," she shared in an in-depth interview with "Entertainment Tonight," which will air on Wednesday evening.

The brunette stunner, who leads an extremely active lifestyle and is a longtime runner, revealed in October that she got her first mammogram.

The American Cancer Society currently advocates for women to get mammogram screenings annually beginning at age 40.

Harris has already received an outpouring of support from her fans, who've been tweeting warm wishes for her.
