She said she has never smoked a cigarette in her life:. In the video, actress Kate Micucci, who also starred in series such as "Scrubs" and "How I Met Your Mother," updated her followers on her condition. She revealed that her cancer had been detected early and could therefore be treated quickly:. The actress, seen lying on a hospital bed and wearing a surgical gown, humorously ended the video by giving the camera a thumbs up while saying, "Why am I still talking … ‘cause I’m on drugs!" . Lung cancer, although more frequent in smokers, can also occur in non-smokers. Radon exposure, secondhand smoke and air pollution are some of the possible causes of lung cancer in non-smokers, according to the American Cancer Society.
