Other factors that may increase the risk include:

• Exposure to secondhand smoke
• Long-term exposure to air pollution
• Occupational exposure to certain substances
• Radon exposure
• Previous radiation exposure to the chest
• Family history and certain genetic factors
• Certain chronic lung conditions

Having a risk factor does not mean that a person will definitely develop lung cancer. Similarly, someone without an obvious risk factor can still develop the disease.
