Asbestos: What It Does to Your Lungs

What is Asbestos?

Asbestos is a fiber that was used as an insulator and fire-retardant in the past. While the EPA and CPSC have banned the use of asbestos for many things and it is no longer used in newer homes, it may still be found in homes and buildings built in a time when asbestos products were available. Asbestos is still used in pipe and furnace insulation, shingles, millboard, textured paints, and floor tiles.

Even without asbestos insulation, this fiber can become airborne through remodeling older homes, or improper protocols when cutting and cleaning up asbestos fibers from new home improvement projects.

Asbestos is also a naturally occurring mineral and can be found in soils and rocks and can be released into the air through construction or weather. So long as the soil and rock remain undisturbed, there is no health risk.

Asbestos and the Lungs

Those who have experienced prolonged exposure to asbestos fibers are at higher risk of lung cancer, mesothelioma and nonmalignant lung and pleural disorders like asbestosis, pleural plaques, pleural thickening, and pleural effusion. The progression of these conditions may continue even after exposure to asbestos has been restricted.

Asbestos-related lung conditions develop over time, up to 15 years or longer after preliminary exposure for those who work(ed) with asbestos. Smokers who are exposed to asbestos are at a significantly greater risk for asbestos-related conditions than non-smokers.

These conditions develop when asbestos fibers are not completely exhaled by the lungs. They remain lodged in the lungs and stay there. As the amount of fibers accumulate over the years, the lung tissue becomes scarred and inflamed. As the scarring and inflammation worsen, it becomes more and more difficult for a person to breathe.

Types of Asbestos-related Conditions


Asbestosis develops when the lung tissues become scarred or inflamed from prolonged exposure. Those who have been exposed to asbestos may develop asbestosis anywhere between 10 to 20 years after initial exposure.

I was exposed to toxic mold in a basement apartment. I have respiratory problems and cough up mucu a lot. At one point I was coghingup some black, which the doctor later said it could be blood that had been sitting. They did a CT scan and it showed a little inflammation, and the brochiascopy results were that there wasn't any bacteria or infection. They have no knowledge of mold contamination so I still haven't gotten check to see if any mold is growing on my lungs. I have shrtness of breath and still coughing up mucus. Can you tell me what I should do.

Mold won't grow in your lungs, but prolonged exposure to it and other airborne contaminants can affect your lungs. A couple of suggestions (please keep in mind that I'm not a doctor but these seem common-sensical to me): Check with your landlord to get the carpeting replaced; If you need to, get a sample of your carpet and have your landlord or doctor have it tested for mold (there are a couple of home improvement TV programs that will do this as part of their show); if you're not getting the attention you believe you need from your doctor do not hesitate to get a second opinion (particularly if you've explained the mold situation to them and they don't seem to think it's an issue); I know this one is difficult, but find a new apartment. You won't be able to undo any damage to your lungs, but you can prevent any more damage from being done. I would go with the first few suggestions to start before going with this one. You want to be sure that wherever you live and work is safe.

Mold will also grow in walls, furniture (bedding, sofa, chairs) and curtains and drapes.

Again, please don't take this as a medical professional opinion.

I hope this helps.
