Risk Factors

Smoking cigarettes, pipes or cigars is the most common cause of lung cancer. The amount of smoking increases a person’s risk. A person who smokes two packs a day for 20 years has a greater risk than someone who smoked occasionally for a few years, but all smokers and people exposed to significant second hand smoke have an elevated risk—regardless of the amount of time they smoked or were exposed to smoke. Though risk doesn’t disappear when a person stops smoking, it does decrease as the years pass.

Risk factors for disease include anything that increases a person’s chance for developing a disease. However, having a risk factor doesn’t mean you’ll get the disease, and not having any risk factors does not mean you won’t get a disease. While smoking has been proven biochemically to cause lung cancer, other risk factors are simply more commonly observed in patients who develop cancer without establishing them as causing the disease. Risk factors for lung cancer are:

  • Smoking cigarettes, pipes or cigars, now or in the past
  • Being exposed to secondhand smoke
  • Being treated with radiation therapy to the breast or chest
  • Being exposed to asbestos, radon, chromium, nickel, arsenic, uranium, soot or tar

Reducing Your Risk

Quitting smoking, or never starting to smoke, is the single best way to reduce your risk for lung cancer, other lung and throat diseases, and the many diseases and conditions caused by or related to smoking. If you smoke, we urge you learn more about how to successfully quit.
