Asbestos and Pleural Mesothelioma
Text credit: Pleural Mesothelioma Center

Asbestos is categorized into six naturally occurring silicate minerals. Throughout much of the 20th century, asbestos was used in more than 3,000 construction materials because of its insulating and fireproofing capabilities. Unfortunately, exposure to asbestos is known to cause a rare cancer called mesothelioma. In most cases, asbestos exposure occurs by inhaling airborne asbestos fibers after asbestos-contaminated materials have been disturbed. Check for more information if you're exposed to asbestos.

Types of Asbestos

The six different types of asbestos are divided into two distinct groups – serpentine and amphibole. Serpentine asbestos has curly fibers and a layered structure. Chrysotile asbestos is the only type under this category. Amphibole asbestos has a long chain-like structure with straight, sharp fibers that are easy to inhale. Under the amphibole category, there are five types of asbestos, including amosite, crocidolite, anthophyllite, tremolite and actinolite.

Asbestos Exposure

Pleural mesothelioma is almost exclusively caused by asbestos exposure. Because asbestos was such a widely used mineral for most of the 1900s, many commercial workers encountered it on a daily basis and transported fibers home on their clothing, placing their families at risk as well. Most current mesothelioma patients can link their condition to occupational asbestos exposure.

While asbestos is a toxic mineral, symptoms of mesothelioma may not arise until 20 to 50 years after exposure. This latency period is largely responsible for most cases being diagnosed during a late stage of development. The average mesothelioma life span ranges between four and 18 months following diagnosis. Although there is not a definitive cure available, some patients may elect to receive palliative treatments to ease pain and discomfort.
