Key statistics.

  • The primary CAUSE of lung cancer is smoking; radon is the leading cause of cancer in non-smokers. Up to 16% of people with lung cancer never smoked a day in their lives.
  • Doctors estimate that the smoker's high RISK FOR LUNG CANCER IS LOWERED TO ALMOST NORMAL just 10 years after he or she stops.
  • Finding lung cancer at the earliest, most curable stage is difficult. There MAY BE NO SYMPTOMS IN THE BEGINNING to warn a person to see a doctor.
  • Signs which suggest something's wrong - A CHRONIC COUGH, WEEZING, CHEST PAINS, COUGHING UP BLOOD - which can also occur in other chest diseases.
  • Lung cancer can be TREATED IN THREE WAYS: surgery, radiation therapy, and chemotherapy.


  • The primary cause of lung cancer by far is SMOKING.
  • RADON gas build-up in homes is the second leading cause of lung cancer. For smokers, there is a 30% risk of lung cancer with a lifetime exposure to high radon levels (800Bq/m3 or higher). Learn more about radon here.


KEY Prevention stratEgies

The risk for lung cancer changes if the person stops smoking.
