Asbestos cancer is a malignant tumor caused by exposure to asbestos fibers. Asbestos exposure is most commonly associated with mesothelioma and lung cancer. Mesothelioma is a rare cancer affecting the lining of the lungs, heart, and abdomen, while traditional lung cancer occurs in the tissue of the lung’s lobes.

What is Asbestos?

For most individuals, especially those born in the last 40 years, the mention of asbestos conjures up thoughts of a dangerous substance that's sickened many people and caused myriad deaths around the world. That's an accurate description.

A common misconception on the part of many individuals, however, is that asbestos is a hazardous man-made substance, conjured up in factories around the world for commercial use. The truth is, however, that asbestos is a naturally-occurring mineral that can be found in hundreds of countries on just about every continent. As a matter of fact, asbestos is still mined in several of these countries, including Canada and Russia. Other countries have outlawed the mining of asbestos.
Asbestos is a highly-fibrous mineral with long, thin, separable fibers. The thin fibers can be spun and woven together, and possess valuable heat-resistant properties that make asbestos suitable for insulation and other such products. Indeed, for decades, asbestos was the material of choice for many industries that were manufacturing products for which heat resistance, low electrical conductivity, flexibility, and high tensile strength were essential factors. Today, there are other alternatives.
There are two kinds of asbestos. The serpentine variety is curly. Chrysotile asbestos, most commonly used for industrial purposes, is from the serpentine family. Other asbestos fibers, from the amphibole family, are very straight and needle-like. Amosite, crocidolite, tremolite, actinolite, and anthophyllite are amphibole asbestos varieties.
Currently, chrysotile asbestos is the only type mined on a wide-scale though a handful of countries continue to mine other forms. However, worldwide outrage about the use of dangerous asbestos has forced many countries to reconsider their position on mining.
