Mesothelioma Risk Factors
Mesothelioma Risk Factors
In as many as 75-85% of mesothelioma
cases, there is a history of exposure to asbestos. The material was used
extensively in numerous industries from the early 1900’s through the
1960’s. Through the World War II era, over 8 million workers were exposed
to asbestos. Evidence that serious health problems were related to
asbestos began to mount, and in 1999, a conclusive link between asbestos
exposure and mesothelioma was made.
Because it can take as long as 50 years
for mesothelioma to develop, anyone who has been exposed should be
evaluated by a physician experienced in this form of cancer. Even if you are not
ill, you should learn about your legal rights in case mesothelioma is
found in the future.
Asbestos is a broad term which refers to
a collection of minerals know as asbestiform. It is a small mineral comprised of
tiny fibers. Asbestos fibers exist in two forms; they can be either
amphibole or serpentine (chrysotile). Several studies suggest that the
amphibole form of asbestos is more dangerous than the chrysotile form,
especially in mesothelioma.
These small particles float in the air,
in an exposed environment and they may be inhaled or swallowed. Asbestos fibers
breathed into the lungs cannot be expelled; they become embedded in the thin
lining of the lungs, the mesothelium. Over the period of many years, cells
in the mesothelium can become cancerous. In most cases of
mesothelioma, it takes decades for the disease to cause symptoms.
Although a serious hazard to your health,
asbestos is an excellent insulating material. It is used in many products
that need to withstand high heat such as home insulation and construction, brake
pads, electrical equipment, hot water piping, boilers, ship engines, and welding
supplies. People who have worked in these industries should be screened
regularly for the development of lung disease.
When the asbestos is contained within
finished products such as walls and tiles, it does not appear to pose a health
as long as it is not damaged or disturbed. However, damage or
inadvertent destruction can release dangerous fibers into the air. When asbestos
fibers are set free and inhaled, however, exposed individuals are at risk of
developing an asbestos-related disease.
While smoking has not been found to cause
mesothelioma, smoking has been linked to an increased incidence in
mesothelioma in asbestos exposed workers. Therefore, if you have had
occupational e exposure to asbestos, smoking could raise the risk of developing
mesothelioma.
Asbestos exposure
The most common way in which people are exposed to asbestos is through
their work. There are a number of jobs in which exposure to asbestos may have
occurred. Asbestos has been extensively used in industrial products, including
cement, brake linings, roof shingles, flooring products, textiles, and
insulation as well as shipbuilding and other forms of construction. The
risk of developing Mesothelioma increases according to the length and
level of exposure to asbestos.
The number of workers exposed to asbestos
far exceeds the number of documented cases. The reasons why some people
who are exposed to asbestos do not develop the disease are not well
understood.
The risk of developing asbestos-related
diseases varies with the type of industry in which the exposure occurred and
with the extent of the exposure. According to the Environmental Protection
Agency (EPA) there is no safe level of exposure to asbestos fibers. The
Occupational Safety and Health Administration (OSHA), however, has set a
Permissible Exposure Limit (PEL) of 0.1 fibers per cubic centimeter (f/cc) for
an 8 hour time weighted average. The safest course of action is to limit
exposure and always wear protective gear when dealing with any type of suspected
asbestos.
Hidden asbestos risks
The risk of developing mesothelioma is not just confined to the
person directly exposed but may extend to family members and friends of those
directly exposed. Even someone who has not been directly exposed or has been
exposed at very low levels is at risk may develop the disease.
An increasing incidence of
mesothelioma in spouses and children whose only to asbestos was from the
dust laden work clothes of a family member is being reported. People
who were in contact with workers in asbestos related injuries should also be
vigilant for symptoms and be screened for lung disorders regularly.
