Radon, an odorless gas that is the result of the natural decay of uranium, has been identified as a risk factor for lung cancer. It's most often found in the soil beneath houses and can seep up into a home. Secondhand smoke from fireplaces, campfires and wood-burning stoves is a risk factor as well. Finally, some people work in occupations that increase their risk for lung cancer because of exposure to asbestos, heavy metals, diesel fuel and coal. That risk increases if you smoke.
Should you be screened for lung cancer?
“If any of the above risk factors apply to you, or if you have a family history of lung cancer, talk to your primary care doctor to see if you qualify for a lung cancer screening,” said Dr. Gillespie.
You should also get checked if you experience any of the following symptoms:
- Persistent cough
- Chest pain
- Coughing up blood
- Unexplained weight loss
Screening is recommended if you're in these high-risk groups:
- 20 pack-year smokers between the ages of 50 and 80 who have quit smoking within the last 15 years.
- A pack-year means that you have smoked one pack of cigarettes a day for the last 20 years, two packs a day for the last 15 years, etc.
Do you need help quitting smoking?
“Because smoking is one of the biggest risk factors for lung cancer, it is never too late to quit,” said Dr. Gillespie.
