Who Gets Non-Small-Cell Lung Cancer?

Risk Factors for Non-Small-Cell Lung Cancer (NSCLC)

* Age: The risk of NSCLC increases with age. Most people who get NSCLC are over age 65.

* Smoking: Smoking is the leading risk factor for NSCLC. About 80% of people who get NSCLC are current or former smokers.

* Secondhand smoke: Exposure to secondhand smoke can also increase the risk of NSCLC.

* Radon gas: Radon gas is a radioactive gas that can cause lung cancer. Radon is found in the air and soil, and it can enter homes and buildings through cracks in the foundation.

* Asbestos: Asbestos is a mineral fiber that can cause lung cancer. People who work with asbestos or who live near asbestos mines or factories are at increased risk of NSCLC.

* Other lung diseases: People with certain lung diseases, such as chronic obstructive pulmonary disease (COPD), are at increased risk of NSCLC.

* Family history of lung cancer: People with a family history of lung cancer are at increased risk of the disease.

People who have any of these risk factors should talk to their doctor about ways to reduce their risk of NSCLC.
