Lucy Davis, best known for playing receptionist Dawn Tinsley in the original U.K. edition of “The Office,” has revealed that she has terminal cancer.

Writing on Instagram, Davis said she was diagnosed with Stage 4 breast cancer a year and a half ago after discovering a lump on her breast. The cancer had “metastasized to my bones,” she said, specifically her spine, right hip, and ribs, and was “incurable, and too late for chemo.”

“As of now, I’m trying to live out whatever might be left of my life in as fun a way as I possibly can. I always like to find the teachable moments in anything negative that happens. And cancer has not disappointed in that regard; there’s a lot I have learned from it, and I’m grateful for that,” she wrote.

“The thing that has been most vital to me is humour. I asked my friends and family to make fun of me as much as possible (which they’re really good at), and most importantly of all to not treat me like a sick person. There’s nothing that will make you feel more unwell than being treated as if you’re unwell.”

Davis, who also appeared in cult British comedy “Sean of the Dead” and later 2017’s “Wonder Woman” added: “I’m not scared of whatever comes next. I’m at peace with it.”
