Thanks for the reply, and I do see your point.

Has anyone ever heard figures about the number of people who DO NOT smoke who get lung cancer?

It would be an intersting statistic

Thanks for the reply, and I do see your point. Has anyone ever heard figures about the number of people who DO NOT smoke who get lung cancer? It would be an interesting statistic.

The percentage of lung cancer patients who have never smoked is approximately 10%.

Each year, over 170,000 Americans develop lung cancer, and approximately ten per cent of lung cancers, or 17,000 cases, occur in non-smokers.
