A 37-year-old UK mum coughed up a three-quarter-inch tumor, an incident that probably saved her life.

When Claire went to her GP and the biopsy revealed cancer, it was suggested that she needed chemotherapy to get rid of any remaining cancer. But doctors were surprised to find no evidence of cancer after conducting a positron emission tomography (PET) scan.
“The consultant turned round to me and said, ‘It appears you have coughed up your cancer. Congratulations,’” Osborn told the Daily Mail. “I was totally flabbergasted. I couldn’t believe a coughing fit had saved my life.” Later on she underwent a minor surgery to get rid of any possible cancer that might have been left behind.
Dr. Gary Walton, the head and neck surgeon who treated her, said that it was not impossible to cough out the cancer as it probably grew on a stalk at the back of her mouth.
