Lung Cancer Screening 

​​

Why and who do we screen?

​

Lung cancer is the most common cancer in Canada. We now have an effective way to screen those at high risk of lung cancer. When found early, treatment has a higher likelihood of being successful. Cancer screening is testing done on people who are at risk of getting cancer, but who have no symptoms and generally feel fine. Screening is not for everyone. People who are not at high risk of getting lung cancer should not get screened because there may be more potential harms than potential benefits for them.

Those who are considered high risk of lung cancer may be eligible* for screening if they:

• are 55 to 80 years old

• have smoked cigarettes every day for at least 20 years (it does not have to be 20 years in a row, which means there could be times when you did not smoke), and

• have Ontario Health Insurance Plan (OHIP) coverage

How do we screen?

Lung cancer screening is done with a type of computed tomography (CT) scan that uses a small amount of radiation. This test is called a low-dose CT scan.

Prevention

Don't Smoke - your risk of lung cancer increases with the amount of smoke exposure (both first- and second-hand).

Limit exposure to noxious chemicals - Asbestos, radon, air pollution and other chemicals can increase risk of certain types of lung cancer and lung diseases. Ensure you limit your exposure and use appropriate PPE (personal protective equipment) where possible.

Live a healthy lifestyle - eating a diet rich in fruits and vegetables reduces your risk of lung cancer.
