Kayley Boda, a 22-year-old retail assistant from Manchester, UK, was diagnosed with lung cancer after she began smoking as a teenager. Initially thought her symptoms were a side effect of her smoking habit, but they worsened when she began coughing up a substance that had "grainy" pieces. She underwent surgery to remove half of her right lung and began chemotherapy, but returned to the doctors a month later with a pleural effusion, which doctors discovered was in her lungs' pleural lining. Boda's medical team has given her 18 months to live and is urging others to quit smoking.
