Why and when should I get screened for lung cancer?

Your doctor may recommend a lung cancer screening or diagnostic test, but that doesn’t mean he or she thinks you have cancer. If you are at risk for developing lung cancer or have certain symptoms, there are screening tests that can detect cancer early. Getting tests, like chest x-rays or chest CTs, have helped detect cancer and decrease the risk for getting lung cancer.

Lung Cancer Risk Factors

There are many factors that could increase your chance of developing lung cancer, some you can control and some you cannot. It may be beneficial to be screened if you

Smoked or were exposed to smoke

The number of cigarettes smoked and the years you’ve been smoking significantly increases the chance of cancer.

Quitting at any age can lower this risk.

Exposure to secondhand smoke can also increase your risk of lung cancer.

Were exposed to radon gas, asbestos, or other carcinogens

Exposure to these substances can be unsafe when exposed to high levels, and they have been known to cause cancer.

Have a family history of cancer.

If you have a family member who had lung cancer, you have an increased risk of getting the disease.
