17. What are the chances of developing a second lung cancer?

A person who has had lung cancer once is more likely to develop a second lung cancer compared to a person who has never had lung cancer. Second cancers arise in a different site than the original cancer. If the original cancer returns after treatment, it is considered recurrent, not a second cancer. Quitting smoking after lung cancer is diagnosed may prevent the development of a second lung cancer.
