For ex-smokers. A limited study has shown some evidence that your lungs can replace smoking-damaged cells over time.
The study’s joint senior author, Peter Campbell of the UK-based Wellcome Sanger Institute, said the results should give new hope to smokers who want to quit.
“People who have smoked heavily for 30, 40 or more years often say to me that it’s too late to stop smoking – the damage is already done,” he said in a statement issued by the institute.
“What is so exciting about our study is that it shows that it’s never too late to quit.”
