How can lung cancer be prevented?

Smoking cessation is the most important measure that can prevent lung cancer. Many products, such as nicotine gum, nicotine sprays, or nicotine inhalers, may be helpful to people trying to quit smoking. Minimizing exposure to passive smoking is also an effective preventive measure. Using a home radon test kit can identify and allow correction of increased radon levels in the home, which can also cause lung cancers. Methods that allow early detection of cancers, such as the helical low-dose CT scan, may also be of value in the identification of small cancers that can be cured by surgical resection and prevention of widespread, incurable metastatic cancer.
