The Silent Threat: Radon and Lung Cancer in Non-Smokers

Every week, I meet patients who are shocked to learn they have lung cancer despite never having smoked a day in their lives.

So what’s behind it?

Radon: The Invisible Killer in Our Homes

Radon is a naturally occurring, colorless, odorless radioactive gas that seeps into homes from the soil. You can’t see it, smell it, or taste it — but long-term exposure damages lung tissue and silently increases your cancer risk.

It’s not rare. In fact, radon is the number one cause of lung cancer in non-smokers and the second leading cause overall, right behind smoking.

Why It Matters Here in Nebraska & Iowa

Our region sits on geological formations that naturally release higher levels of radon gas. Studies show that a majority of homes in Eastern and Central Nebraska and Southwest Iowa exceed the EPA’s recommended safety threshold. Without testing, you’d never know.

What You Can Do

Testing for radon is simple, inexpensive, and can be done in just a few days using a home test kit from your local health department or hardware store.

If your levels are high, certified mitigation systems can reduce radon to safe levels by venting it outside — often within a single day.

My Message as a Thoracic Surgeon

Lung cancer caught early is treatable, but prevention saves lives.

Don’t wait for symptoms — by then, it’s often too late.

Take action today:

  1. Test your home for radon this month.
  2. Encourage your friends, neighbors, and patients to do the same.
  3. If elevated levels are found, schedule a mitigation consultation immediately.

Protect your home. Protect your family. Protect your lungs.

Learn about lung cancer screening eligibility and talk to your doctor for a referral.
