Lung Cancer (cont.)
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.
- Lung cancer is the number-one cause of cancer deaths
in both men and women in the U.S. and worldwide.

cancers (NSCLC).
- The stage of lung cancer refers to the extent to which
the cancer has spread in the body.
- Treatment of lung cancer can involve a combination of
surgery, chemotherapy, and radiation therapy as well as newer experimental
methods.
- The general prognosis of lung cancer is poor, with
overall survival rates of about 16% at five years.
- Smoking cessation is the most important measure that can prevent the
development of lung cancer.
