Even years after quitting, former smokers still have a raised risk of lung cancer - and now scientists believe they know why. Smoking appears to permanently alter the activity of key genes, even though most cigarette damage is repaired over time.
Canadian researchers, writing in the journal BMC Genomics, looked at lung tissue of 24 people. UK experts stressed that giving up still delivers massive health benefits.
It has been shown that the poisons in cigarette smoke can alter the activity of genes. If you give up smoking, your risk of lung cancer falls significantly, but former smokers continue to have a slightly higher risk of lung cancer compared with someone who has never smoked.
"We know that giving up smoking massively reduces your chances of developing lung cancer" Spokesman, Action on Smoking and Health
The latest study from the British Columbia Cancer Research Centre in Vancouver suggests that some of these changes might be permanent.
