Lung Cancer

An estimated 228,000 new lung cancers are diagnosed every year in the United States. Although lung cancers can occur at any age, studies show that they are most commonly diagnosed in persons age 65 or older.

What is Lung Cancer?

Lung cancer can be classified as either small cell or non-small cell, depending on the type of cells affected.

Cancers originating elsewhere in the body often metastasize (spread) to the lung. These cancers are not considered to be lung cancers, since the cancer formed elsewhere in the body.

At the time of your diagnosis, your doctor will “stage” your lung cancer. The stage indicates how much your cancer has advanced and where in your body the cancer is located.

The stage of your cancer, along with the type of cancer, will determine what type of treatment will be the most effective.

Risk Factors

Factors that may increase your risk for lung cancer include:

Many studies have shown that air pollution may also increase the risk of lung cancer.

Additionally, people who have had lung cancer have an increased risk of developing a second lung cancer. Family history may also increase your risk. Lung cancer may also appear in people with few or no risk factors.
