FOX News host Kat Timpf has been forced to defend herself from sick online trolls who are questioning her life-altering cancer diagnosis.

Timpf, 36, hit back at revolting comments after she was diagnosed with stage zero breast cancer just hours before giving birth to her first child.

On Thursday, Timpf’s Fox News co-star Greg Gutfield told viewers on his late-night comedy show that Timpf and her husband Cameron Friscia had welcomed their baby boy.

He then shared her cancer diagnosis and wished her well, saying, “We love her. We miss Kat, and I’m sure she’s doing great.”

“She’s a tough little bastard,” joked the Gutfield! host.

Thousands of fans commented on the clip to send their love to the author and co-host, but a few bad actors questioned her diagnosis in disgusting comments.

One person wrote on X, “I would argue whether stage zero cancer is really cancer at all. That’s not a knock on Kat, it’s a knock on our healthcare system and how they are motivated to generate revenue based on these types of misleading diagnoses.”

And another person agreed saying, “And it could be hormonal changes. I hope she doesn’t rush into extreme surgery.”

But Timpf defended her situation and quickly quieted the noise by blasting their bizarre claims.

“It’s not hormonal changes. It is cancer,” the new mom said.

“I promise I know more about my own case than people online and do not take life-altering medical treatments lightly.”

Fans applauded Timpf for her classy comment and sent their prayers as she embraces motherhood and fights a health battle.

“Praying for you. I’m so happy that it was caught early,” said one fan.

Another wrote, “Your son arrived at the perfect time to protect you from the stress of the diagnosis.”

‘HERO’ HOST

Timpf’s Fox News family has rushed to her aid since her announcement and diagnosis as they share their love and encouragement.

Martha MacCallum, who anchors her own daily spot on Fox News, said she was “sending lots of love and strength” after hearing about Timpf’s growing family.

And Kennedy Montgomery, who is a mainstay on Outnumbered and The Fix, described the new mom as “amazing in every way.”

“And you were heroic in labor given the day you’d just had! I love you,” she wrote on X.
