Causes of Mesothelioma

The primary cause of mesothelioma is asbestos exposure. There are numerous professions that are known to have used asbestos and are thus at risk
  • Construction Workers
  • Auto mechanics
  • Building engineers
  • Railroad workers
  • Navy sailors
  • Shipyard employees
  • and others


Workers in these occupations were exposed to asbestos and have become ill from asbestos cancer. However, there are cases of asbestos diseases and mesothelioma in persons with much smaller exposure to asbestos. These cases include families of workers in high-risk professions or those who lived in closed proximity to asbestos manufacturing plants.
Asbestos fibers lodge inside the body and cannot be processed. When breathed in, these fibers damage the mesothelial cells in the pleura or peritoneum The fibers are so tiny that they actually can damage DNA. The injured cells can create lung cancer or mesothelioma.
Since asbestos exposure is the primary cause of mesothelioma, it is important to know how you may have come in contact with asbestos. It is found in both industrial applications and household products, including, but not limited to:
  • Brakes
  • Clutches
  • Plaster
  • Attic Insulation
  • HVAC Duct Insulation
  • Joint Compounds
  • Gaskets
  • Packing
  • Electrical wire
  • Cement Pipe
  • Paint
  • Pipe Covering and Insulation
  • Putties
  • Roofing Shingles
  • Siding
  • Floor tiles
  • Insulating blankets and pads
  • Boilers
  • Turbines
  • Pumps
  • Valves
  • Caulk
  • Spackling Compounds
  • Baby Powder
  • Chalkboards
  • Coffee Pots
  • Hair Dryers
  • Toasters
  • and others


Asbestos has the ability to resist heat, capacity to insulate and flexibility to be woven, making it very popular in industrial applications and home appliances. While there are now limitations for asbestos use, it is still imported regularly in products from other countries.


The latency period for mesothelioma is quite long – as long as 30-50 years. Mesothelioma and other asbestos diseases are often misdiagnosed as other less innocuous illnesses such as the flu. Therefore, it is critical that you let your doctor know if you have been exposed to asbestos or were a spouse or child of one exposed.

What is Asbestos?

Asbestos is a group of naturally occurring silicate minerals that are made up of strands of fibers. When separated, the fibers are strong and flexible enough to be woven. It was often used in industrial settings because of its ability to resist heat, capacity to insulate, and flexibility to be woven.
The two primary types of asbestos are amphibole and serpentine.

Asbestos and Mesothelioma

Asbestos can cause cancer and is the primary cause of mesothelioma, a cancer of the lining around various organs. Because asbestos particles are inhaled, mesothelioma most frequently occurs in the lining of a person's lungs (the pleura). The asbestos particles stay in the body for years without breaking down and can create malignant tumors known as mesothelioma.


Asbestos Diseases

Other asbestos diseases include:
  • Asbestosis, a scarring of the lung tissue
  • Lung cancer

Occupations Affected

Occupations affected by routine exposure to asbestos include but are not limited to:
  • Miners
  • Shipyard workers
  • Sailors
  • Construction workers
  • Plumbers
  • Pipe fitters
  • Boiler workers
  • Insulators
  • Auto mechanics
  • Railroad workers
  • Teachers
  • Medical Professionals
There are documented cases of mesothelioma from far less exposure to asbestos than the professions listed above. These include family members of workers who were in contact with asbestos and brought it home on clothing and individuals who lived close to asbestos manufacturing plants.

Asbestos Health and Environment

Asbestos was used long after the dangers were discovered. Because of its wide-spread use in different industries, the average person will possibly come into contact with asbestos at some point. It is frequently found in older hospitals, schools, and homes.


Asbestos is also found in many common products including:
  • Joint Compounds
  • Brakes
  • Clutches
  • Gaskets
  • Packings
  • Boilers
  • Pumps
  • Valves
  • Engines
  • Roofing shingles
  • Exterior siding
  • Caulking compounds
  • Paints
  • Ceiling and floor tiles
  • Hair dryers
  • Irons and ironing board pads
  • Flame-resistant aprons and electric blankets

Asbestos Removal

Even with the decline in asbestos usage since the 1980's, it is still prudent to use caution when working with older commercial and residential facilities. If you are unsure about the possibility of asbestos in items in your home or facility, contact an accredited asbestos professional to perform an inspection.
If the asbestos materials are in good condition, it is best to leave them alone. They will only become a health risk if disturbed and release airborne asbestos. However, if you find damaged asbestos-containing materials in your home, consult an asbestos professional to handle the removal and disposal of the asbestos.
