What Makes Asbestos Exposure So Dangerous?
Asbestos is a natural material present in the earth. Unlike other minerals, asbestos appears like bundles of fibers when seen under a microscope. People realized that asbestos had a great ability to insulate and provide fire-proofing, so it was incorporated into building and insulating materials. Such building practices remained in place until the late 1980s in most places in the United States, but just living or working in an older building is unlikely to result in illness from asbestos exposure. It requires a more direct contact with the substance for damage to the lungs to occur. Those most at risk for adverse effects of asbestos exposure are those who worked with building materials including asbestos. Shipbuilders, construction workers and miners from the 1940s onward all are at high risk for illnesses resulting from exposure to asbestos. During the course of their job, these workers would daily cut into asbestos-containing products. Preparing asbestos to be installed required cutting the materials, this disturbed the bundles of asbestos fibers, sending them air-borne. Workers would breath in the asbestos fibers, but unlike regular dust particles filtered out by the lungs, asbestos exposure would irritate and inflame the lining of the lungs, creating a condition known as asbestosis. This condition has been seen as a precursor to more serious ailments such as lung cancer or mesothelioma. The risk increases significantly in workers who smoke. The family members of workers are not immune to the ill effects of asbestos exposure. Cutting into the materials containing asbestos products can deposit some of the fibers onto the worker’s clothing. The person at home doing the laundry will be subject to breathing in those asbestos fibers from the clothes, even without direct contact with the material. Though asbestos is no longer in use as a building material, demolition crews and those nearby abandoned buildings are also at risk. Prior to pulling down a building, asbestos remediation and removal must be done by licensed contractors, but some areas allow this step to be skipped if the individual is the one tearing down the old building.

Just as building with asbestos-containing materials can cause the carcinogenic fibers to be released, so can breaking apart a building made with such products. Those in high risk categories and their family members should be aware of the signs of illness from asbestos exposure. Symptoms of lung damage or another condition include: shortness of breath, worsening cough, loss of appetite, pain in the chest or abdomen, swelling in the face or neck, problems swallowing or weight loss. Those experiencing such symptoms and who have worked with building materials during the last half of the 20th century should visit a physician immediately for an evaluation. The scientific mystery of cancer is that not everyone exposed to a carcinogenic substance will develop cancer. Asbestos exposure is not a guarantee of getting asbestosis, lung cancer or mesothelioma later in life, but it greatly increases the chances. Those with a history of exposure to asbestos should do everything possible to adopt a healthy, cancer-preventing life-style to avoid the ill effects of breathing in asbestos.

The best steps to take are the simplest: quitting smoking, adopting a healthy diet and following a regular exercise routine might not ward off cancer, but such measures can help to strengthen the body if an asbestos-related disease does develop.
