‘The Big Bang Theory’ actor reveals lung cancer diagnosis: ‘never smoked a cigarette’

Kate Micucci played Lucy on The Big Bang Theory

Kate Micucci, best known for her role in "The Big Bang Theory", has been diagnosed with lung cancer. The 43-year-old American actress shared news of her diagnosis in a TikTok video.

Micucci said she underwent surgery for lung cancer on Friday. “Hey everybody, this is not a TikTok, it’s a ‘Sick Tok.’ I’m in the hospital but it’s because I had lung cancer surgery yesterday,” the "Raising Hope" actor said in her TikTok video posted Saturday.

“They caught it really early,” she continued. “It’s pretty weird because I’ve never smoked a cigarette in my life. So, you know, it was a surprise, but also, I guess it happens.”

Micucci has appeared on three seasons of ‘The Big Bang Theory" as the shy and awkward Lucy, a woman that Raj meets at a party. Besides "The Big Bang Theory," she has appeared briefly on shows like "How I Met Your Mother," "Weeds," and "Psych."

The actor and comedian has a three-year-old son with her husband Jake Sinclair. “So the greatest news is they caught it early, they got it out, I’m all good,” she said of her cancer diagnosis.

In the comments section of her video, Micucci explained how she found out about her lung cancer. “I had one thing in my bloodwork that came back really high … It was HCRP … not sure what that is exactly but I guess it means there is inflammation somewhere,” Micucci explained. “So I went to a preventative doc who did a few scans. He scanned my heart and that’s where the spot in my lung was noticed.”
