Risk Factors for Lung Cancer

Many people recognize that smoking tobacco can lead to lung cancer. However, lung cancer can develop in anyone, regardless of their smoking status or age. It’s good to be aware of the risk factors, even if you’ve never smoked and believe you are unlikely to develop lung cancer.

Common risk factors

The common risk factors for lung cancer include:

  • Smoking tobacco in any form
  • Having a history of smoking, even if you’ve quit
  • Living or having frequent contact with someone who smokes
  • Working in an environment where people smoke
  • Having other relatives with lung cancer
  • Exposure to radon, chromium, nickel, soot, tar or arsenic
  • Exposure to heavy air pollution
  • Infection with HIV
  • Undergoing radiation therapy to the chest or breast

Risk calculators and resources

There are a number of tools available online that can help you understand how at risk you are for lung cancer. Bear in mind, however, that the results you receive are only an estimate. It’s best to visit your doctor and discuss your risk and concerns in person.

How to lower your risk

Making certain lifestyle changes can reduce your risk of lung cancer. You’d be surprised at how much still lies within your control, even if you’re at a higher-than-average risk.

Quit smoking

Many people who smoke, and especially those who’ve smoked for a period of years, believe that little good could come from quitting. They fear that they’ve already damaged their lungs past the point of repair. But this couldn’t be further from the truth. Quitting smoking is incredibly beneficial, even to patients who’ve already been diagnosed with cancer. It’s amazing how quickly the lungs can start to heal.
