What to Know About Lung Cancer Screening

What is lung cancer screening?

Lung cancer screening is a test used to find lung cancer in people who do not have any symptoms of the disease. It is typically recommended for people who are at high risk for lung cancer, such as those who smoke or have a family history of the disease.

How is lung cancer screening done?

Lung cancer screening is typically done with a low-dose chest X-ray or a computed tomography (CT) scan. A low-dose chest X-ray is a type of X-ray that uses a lower radiation dose than a traditional X-ray. A CT scan is a more detailed imaging test that uses X-rays and computers to create cross-sectional images of the body.

Who should get lung cancer screening?

The United States Preventive Services Task Force (USPSTF) recommends lung cancer screening for adults aged 55 to 80 who smoke or have quit smoking within the past 15 years. They also recommend screening for people who have a history of exposure to asbestos or other lung carcinogens.

What are the benefits of lung cancer screening?

Lung cancer screening can help to detect lung cancer at an early stage, when it is more likely to be curable. Early detection of lung cancer can also lead to less invasive treatment and a better chance for survival.

What are the risks of lung cancer screening?

Lung cancer screening carries a small risk of false-positive results, which can lead to unnecessary anxiety and further testing. There is also a small risk of radiation exposure from the X-ray or CT scan used in screening.

How often should I get lung cancer screening?

The USPSTF recommends annual lung cancer screening for people who meet the criteria for screening.

What should I do if I have a positive screening result?

If you have a positive lung cancer screening result, your doctor will recommend further tests to confirm the diagnosis. These tests may include a biopsy, a procedure in which a small sample of tissue is removed from the lung for examination under a microscope.

Early detection of lung cancer can save your life. If you are at high risk for lung cancer, talk to your doctor about whether lung cancer screening is right for you.
