What studies found

In a study of 517 smokers with stage IA to IIIA non-small cell lung cancer, those who quit after diagnosis had median survival of 6.6 years versus 4.8 years for those who kept smoking, and 5-year survival of 60.6% versus 48.6%.

The catch

Observational, so other differences between the groups may play a part.

What to do

Ask your care team for quit-smoking help as part of treatment.
