Radon and Lung Cancer Risk: National Radon Action Month

Radon is the second leading cause of lung cancer in the United States, yet many people remain unaware of its dangers. This January, during National Radon Action Month, take the time to learn how radon exposure can impact your lung health and the steps you can take to reduce your risk.

What is Radon?

Radon is a colorless, odorless, radioactive gas that forms naturally from the decay of radioactive elements in soil, rock, and water. While low levels are common, high levels of radon in enclosed spaces, like homes and workplaces, can significantly increase the risk of lung cancer.

How is Radon Connected to Lung Cancer?

Prolonged exposure to high radon levels damages lung tissue over time, which can lead to lung cancer. 

Should I get a Lung Screening?

Lung screenings are for people who know they are at a higher risk for developing lung cancer. If you know you have been exposed to radon or work in a field where you are exposed your doctor may recommend that you get regular lung screenings. 

Are There Warning Signs of Radon Poisoning?

Radon exposure does not have specific symptoms, but its effects often manifest as lung cancer. Key warning signs of lung cancer include:

• Persistent coughing

• Shortness of breath

• Coughing up blood

How Can You Be Exposed to Radon?

Radon typically enters homes and buildings through cracks in floors, walls, or foundations. People who work in certain jobs, such as mining, are at an even higher risk of exposure due to prolonged contact with elevated radon levels.

Should You Test Your Home for Radon?

Testing your home is a crucial step in protecting your lung health. The CDC recommends testing:

• When purchasing a home, if it hasn’t been tested before

• Before and after any home renovations

• Before living in lower-level spaces, like basements

Testing kits are affordable and widely available, and addressing radon issues in your home can significantly reduce your risk of lung cancer.

If you think you have been exposed to radon talk to your doctor and see how it increases your chances for lung cancer. This National Radon Action Month, take control of your environment and protect yourself and your loved ones.
