“Big Bang Theory” Star Kate Micucci Reveals Lung Cancer Diagnosis: 'Never Smoked a Cigarette in My Life'

The actress and comedian, 43, said she had a successful surgery to remove the cancer after it was caught early

Big Bang Theory star Kate Micucci revealed she has been diagnosed with lung cancer.

On Saturday, the 43-year-old actress and comedian — who played Lucy on the fan-favorite CBS sitcom — posted a video on TikTok and shared her diagnosis from the hospital after undergoing surgery to remove the disease.

“Hey everybody, this is not a TikTok, it's a ‘Sick Tok,’” she said. “I’m in the hospital but it’s because I had lung cancer surgery yesterday. They caught it really early.”

“It’s really weird, because I’ve never smoked a cigarette in my life so uh, you know, it was a surprise,” Micucci said. “But also I guess, also, it happens and so the greatest news is they caught it early, they got it out, I’m all good.”

Lung cancer is the top cancer killer in the United States, accounting for about 1 in 5 of all cancer deaths. Although smoking is by far the leading cause of lung cancer and it is rare for someone who has never smoked to be diagnosed, it is possible.

According to the American Cancer Society, lung cancer in people who don't smoke can be caused by exposure to radon, secondhand smoke, air pollution, or other factors.

When lung cancer is diagnosed at an early stage, 70 percent live at least five years. Once lung cancer spreads to other parts of the body, long term survival is as low as five percent.

“It’s been a little bit of a trip and [I’ll] probably be moving slow for a few weeks but then I’ll be back at it,” Micucci said, adding that she can’t wait to get back to painting.

“Why am I still talking ... ‘cause I’m on drugs!” she quipped while giving a thumbs up.

The post also included a video of Micucci walking slowly through the hospital in her gown while wheeling along her IV drip.

In the comments section, the star answered one fan who asked if she had any symptoms that made her go get checked out.

“I had one thing in my bloodwork that came back really high,” she explained, noting later that she had high CRP levels, meaning there was a lot of inflammation. “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.”
