Indoor Air Can Cause Health Problems

Are you worried about the air you breathe? Don't assume you're safe just because you're inside. The Environmental Protection Agency (EPA) says that the air within homes and other buildings can be more seriously polluted than the outdoor air in even the largest and most industrialized cities.

Indoor air pollution can have significant health problems. People who may be exposed to indoor air pollutants for the longest periods of time -- children, elderly adults and people with chronic illnesses -- are often those most susceptible to the effects of indoor air pollution.

Most indoor air pollution comes from sources that release gases or particles into the air. Sources such as building materials and air fresheners release pollution continuously. Other sources such as tobacco smoke and wood-burning stoves are related to activities. Although some indoor air pollutants have been around for years, they often were diluted by outdoor air seeping into the home. Today's more energy-efficient homes don't allow as much outdoor air to enter.

Lung Cancer FAQs

You could be forgetting an important question about lung cancer.

Can I Get Checked for Lung Cancer Before I Have Symptoms?

Screening is the search for cancer in people who do not have any symptoms. At this time, no major medical organizations recommend routine screening for lung cancer, even in people at increased risk, although this may change soon. Some doctors may recommend testing in people who are at higher risk for lung cancer, such as current or former smokers, but not all doctors agree on this. 

There are three ways that doctors may try to screen for lung cancer.

  • Sputum cytology test

  • Chest X-rays

  • CT scans

These are described below.

Sputum cytology test. For this test, you use a special jar to collect a sample of the mucus that you cough up and take it to your doctor. Then, it’s checked for cancer cells under a microscope. Not all types of lung cancer will show cancer cells in the sputum.
