What is Mesothelioma? (Provided by
http://en.wikipedia.org/wiki/Mesothelioma)
Mesothelioma is a form of cancer that is almost always caused by previous exposure to
asbestos.
[1] In this disease, malignant cells develop in the
mesothelium, a protective lining that covers most of the body's internal organs. Its most common site is the
pleura (outer lining of the
lungs and chest cavity), but it may also occur in the
peritoneum (the lining of the abdominal cavity) or the
pericardium (a sac that surrounds the
heart).
Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles, or have been exposed to asbestos dust and fibre in other ways, such as by washing the clothes of a family member who worked with asbestos, or by home renovation using asbestos cement products. Unlike lung cancer, there is no association between mesothelioma and smoking

Mesothelioma is caused by Asbestos? (Provided by
http://en.wikipedia.org/wiki/Asbestos)
Asbestos (a misapplication of
Latin: asbestos "
quicklime" from
Greek ἄσβεστος: a, "not" and sbestos, "extinguishable") describes any of a group of minerals that can be fibrous, many of which are
metamorphic and are
hydrous magnesium silicates.
The name is derived for its historical use in lamp wicks; the resistance of asbestos to fire has long been exploited for a variety of purposes. Asbestos was used in fabrics such as
Egyptian burial cloths and
Charlemagne's tablecloth (which according to legend, he threw in a fire to clean). Asbestos occurs naturally in many forms (see below); it is mined from metamorphic rocks.
When asbestos is used for its resistance to fire or heat, the fibers are often mixed with
cement or woven into fabric or mats. Asbestos is used in
brake shoes and
gaskets for its heat resistance, and in the past was used on electric oven and hotplate wiring for its
electrical insulation at elevated temperature, and in buildings for its
flame-retardant and insulating properties,
tensile strength, flexibility, and resistance to chemicals. The
inhalation of amphibole
asbestos fibers can cause a number of serious illnesses, including mesothelioma and
cancer. Since the mid 1980s, many uses of asbestos are banned in multiple countries.

Malignant mesothelioma is caused by
asbestos exposure. There is a latency period of 20 to 50 years or more between initial exposure and development of the disease with the average being between 35 and 40 years. Rare instances have been documented when the interval was less than 20 years.
The incidence of mesothelioma rises with the intensity and duration of exposure to asbestos. However, there are numerous cases of mesothelioma among people with very little occupational exposure or even household exposure. There are cases of people getting mesothelioma 30 or 40 years after a summer job working construction, and cases of housewives or children being exposed from work clothing. Many people being diagnosed with mesothelioma now were exposed in the Navy many years ago, often unknowingly.
What are some symptoms? (Provided by
http://en.wikipedia.org/wiki/Mesothelioma)
Mesothelioma that affects the pleura can cause these signs and symptoms:
chest wall pain
pleural effusion, or fluid surrounding the lung
shortness of breath
fatigue or anemia
wheezing, hoarseness, or cough
blood in the
sputum (fluid) coughed up
How can Mesothelioma be treated? (
http://www.mesotheliomaweb.org/treat.htm)
There are three traditional kinds of treatment for patients with malignant mesothelioma:
Surgery (taking out the cancer)
Chemotherapy (using drugs to fight the cancer)
Radiation Therapy (using high-dose x-rays or other high-energy rays to kill cancer cells)
