Risk Factors For Lung Cancer

  • Cigarette smoking is the number one risk factor for lung cancer. People who smoke cigarettes are 15 to 30 times more likely to get lung cancer or die from lung cancer than people who do not smoke.
  • Secondhand smoke. Smoke from other people’s cigarettes, pipes, or cigars also causes lung cancer. When a person breathes in secondhand smoke, it is like he or she is smoking.
  • Radon is a naturally occurring gas that comes from rocks and dirt and can get trapped in houses and buildings. It cannot be seen, tasted, or smelled. An inexpensive kit is available at hardware stores to test your home for radon.
  • Other substances. Examples of substances found at some workplaces that increase risk include asbestos, arsenic, diesel exhaust, and some forms of silica and chromium.
  • Personal or family history of lung cancer. If you are a lung cancer survivor, there is a risk that you may develop another lung cancer, especially if you smoke. Your risk of lung cancer may be higher if your parents, brothers or sisters, or children have had lung cancer.
  • Radiation therapy to the chest. Cancer survivors who had radiation therapy, a treatment for cancer to the chest, are at higher risk of lung cancer.
