So what exactly is Mesothelioma?
And how do you say it?
Pronounced (Mez-Oh-Thee-Lee-Oh-Mah)
Mesothelioma is a cancer that affects the lining around the lungs, heart, and abdominal cavities - called the mesothelium - which is primarily caused by chronic exposure to asbestos or asbestos related products. As asbestos fibers enter the body, either by breathing or swallowing, they cause normally healthy cells to mutate into cancer. This exposure can come directly, such as working in an asbestos processing center, or indirectly by inhalation of residual asbestos particles remaining on clothing or building materials. Studies show that exposure as short as one year can cause a variety of asbestos-related illnesses, including mesothelioma.
In Mesothelioma, cells of the mesothelium become abnormal and divide without control or order. They can invade and damage nearby tissues and organs. Cancer cells can also metastasize (spread) from their original site to other parts of the body. Most cases of mesothelioma begin in the pleura or peritoneum.
What is Asbestos?
Asbestos is a natural mineral with unusual qualities. It is strong enough to resist high temperatures, chemical attack and wear. A poor conductor, it insulates well against heat and electricity.
Asbestos crystals become long, flexible, silky fibers, so it can be made into a wide variety of forms. It can be spun into yarn, woven into cloth or braided into rope. Asbestos can also be added to materials as diverse as cotton and cement.
This combination of properties gives asbestos performance capabilities that are difficult to match.
What has asbestos been used for?
Asbestos has been used in hundreds of applications and products over the past 4,500 years.
until the 1980s, asbestos was used in office buildings, public buildings and
schools. It insulated hot water heating systems, and was put
into walls and ceilings as insulation against fire and sound.
Asbestos has also been widely used in transportation and electrical appliances,
frequently mixed with, and encased in, other materials. Asbestos has also been
found in many products around the house. It has been used in clapboard; shingles
and felt for roofing; exterior siding; pipe and boiler covering; compounds and
cement, such as caulk, putty, roof patching, furnace cement and driveway
coating; wallboard; textured and latex paints; acoustical ceiling tiles and
plaster; vinyl floor tiles; appliance wiring; hair dryers; irons and ironing
board pads; flame-resistant aprons and electric blankets; and clay pottery.
Loose-fill vermiculite insulation may contain traces of “amphibole” asbestos.
During the 1800s, it insulated the hot engines, boilers and piping that powered
the Industrial Revolution. In ancient times Greeks wove it into oil lamp wicks, funeral shrouds and ceremonial tablecloths.
