Quick Check:

Are You Eligible for
Lung Cancer Screening?

Answer a few quick questions to find out if lung cancer screening may be right for you.

What is the
PLCOm2012 model?

The PLCOm2012 risk calculator is a validated scientific tool that estimates your risk of developing lung cancer over the next six years based on factors such as age, smoking history, medical history (for example, COPD or prior cancer), and body-size.

It was developed from the large scale PLCO (Prostate, Lung, Colorectal & Ovarian) Cancer Screening Trial, and has been shown to help identify people at higher risk who may benefit from early screening.

At the Lung Health Foundation, we believe every Canadian deserves the best possible information to make informed decisions about their lungs. This calculator gives you an estimate, not a diagnosis.

What is Lung Cancer Screening?

Lung cancer is the leading cause of cancer death in Canada. This is often because it’s found late, when it has already spread or grown too large for treatment to work well.

Screening helps find cancer early.

It’s a test for people who may be at risk but don’t have any symptoms and feel healthy.

We now have a proven way to screen people at higher risk for lung cancer. Those who qualify are invited for a quick, safe, and painless low-dose CT scan of their lungs. This scan can find small changes before symptoms appear, giving treatment a better chance to work. Early detection through lung cancer screening could save your life.

Is this tool right for you?

This calculator is designed for adults in Canada who:

Are older than 55 years of age

Have smoked cigarettes every day for about 20 years in total, even if there were times when you quit or took a break.

Have no signs of lung cancer (e.g. a cough that won’t go away, coughing up blood, chest pain, trouble breathing, unexplained weight loss, or feeling very tired all the time).

Why it matters and what you can do

Lung cancer remains the leading cause of cancer-related death in Canada. Yet when detected early, outcomes improve significantly. Knowing your risk gives you information — and power — to act. steps are right for you.

Have you had cancer before?

What you’ll need to get started

The calculator takes about 2-3 minutes to complete. Having these ready will make the process smoother:

Your height and weight (to calculate BMI), your age, and education level

Your smoking history, including cigarettes per day, years smoked and, if applicable, when you quit.

Have no signs of lung cancer (e.g. a cough that won’t go away, coughing up blood, chest pain, trouble breathing, unexplained weight loss, or feeling very tired all the time).
