Protective cells in the lungs of ex-smokers could explain why quitting smoking reduces the risk of developing lung cancer, Cancer Research UK-funded researchers have determined.

Scientists from the Wellcome Sanger Institute and UCL have discovered that compared to current smokers, people who had stopped smoking had more genetically healthy lung cells, which have a much lower risk of developing into cancer.
