Kathy Griffin is encouraging fans to stay up to date on medical check-ups as she reveals a stage 1 lung cancer diagnosis.

In a statement on social media Monday morning, the comedian, 60, announced that she will undergo surgery to have part of her left lung removed, adding that she "hopefully" won't need to have chemotherapy or radiation treatments afterward.

"I've got to tell you guys something. I have cancer. I'm about to go into surgery to have half of my left lung removed. Yes, I have lung cancer even though I've never smoked!" Griffin wrote on Twitter and Instagram.

"The doctors are very optimistic as it is stage one and contained to my left lung. Hopefully no chemo or radiation after this and I should have normal function with my breathing. I should be up and running around as usual in a month or less."

"It's been a helluva 4 years, trying to get back to work, making you guys laugh and entertaining you, but I'm gonna be just fine," she continued, adding, "Of course I am fully vaccinated for Covid. The consequences for being unvaccinated would have been even more serious. Please stay up to date on your medical check ups. It's save your life. XXOO, KG."

In March 2020, Griffin had a health scare when she experienced COVID-19-like symptoms amid the pandemic, at one point visiting the emergency room after experiencing "unbearably painful" symptoms, including nausea, diarrhea, chills and a sore throat. At the time, she posted a photo of herself in a hospital bed wearing a mask.

The star married longtime beau Randy Bick on New Year's 2020 in what she described alongside a clip on Twitter at the time as a ceremony lasting "just under 14 minutes." Griffin's video of the nuptials was only of the first minute or so, and showed Lily Tomlin officiating.

Back in 2017, Griffin made headlines when she shaved her head to stand in solidarity with her sister Joyce as she underwent chemotherapy while battling cancer. In a series of photos posted on Twitter, Griffin posed alone and topless in front of bushes outdoors, smiling with pride and holding her right hand on her bare head.

The comedian's mom Maggie died in March 2020. A year before, in January 2019, Griffin had revealed that her mother had been diagnosed with dementia.
