Lung Cancer Awareness Month: Why early detection matters

November is Lung Cancer Awareness Month—a time to share knowledge, encourage screening, and support those affected by one of the most common and serious cancers in Canada.

Lung cancer remains the leading cause of cancer-related death among both men and women. But there’s good news: when found early, lung cancer can often be treated successfully. That’s why awareness and screening are so important.

 

Who is at risk for lung cancer?

While anyone can develop lung cancer, certain factors can increase your risk:

  • Smoking: The main cause of lung cancer, though risk decreases after quitting.
  • Second-hand smoke exposure: Breathing in others’ smoke also raises your risk.
  • Radon: A naturally occurring gas that can build up indoors without being detected.
  • Air pollution or workplace exposures: Long-term exposure to certain chemicals or pollutants can contribute to lung damage.

Even if you quit smoking years ago—or never smoked—it’s still important to be aware of your risk factors and talk to your healthcare provider about screening.

 

Screening and early detection of lung cancer

Many people with lung cancer don’t notice symptoms until the disease has advanced. Screening can help detect lung cancer early, when treatment is more likely to be effective.

In Canada, some provinces now offer lung cancer screening programs for people at higher risk (such as adults aged 55–74 with a history of smoking). Screening typically involves a low-dose CT scan, which can identify small changes in the lungs before symptoms appear.

Ask your healthcare provider if you qualify for lung cancer screening and how to access it in your province.

 

Taking steps to protect your lung health

You can lower your risk and protect your lungs by:

  • Quitting smoking (it’s never too late to benefit from quitting)
  • Testing your home for radon and mitigating if levels are high
  • Avoiding second-hand smoke and air pollutants
  • Staying physically active and maintaining a healthy diet

 

Lung Cancer Awareness Month is a reminder that early detection can help save lives. Understanding your risk, talking to your healthcare provider, and potentially participating in screening programs can make a real difference.
