The mesothelium that covers the internal organs is called visceral mesothelium, while the coating on the body wall is called the parietal mesothelium.

The mesotelium tissue also surrounds the male internal reproductive organs and covers the internal reproductive organs in women.

Mesothelioma is an aggressive cancer of the mesothelium, in which cells of the mesothelium become abnormal and divide uncontrollably. They can invade and damage tissues and organs. Most cases of mesothelioma arises from the thoracic cavity (pleura) or the abdominal cavity (peritoneum)

Approximately 2000-3000 cases of mesothelioma are diagnosed each year in the United States, covering about 3 percent of all cancer diagnosis. This cancer occurs four times more common in men than in women. Any form of mesothelioma is fatal, with the exception of benign mesothelioma. The prognosis for mesothelioma is almost always poor and most studies report a median survival of less than a year, but the outlook really depends on how early the diagnosis is made and if it aggressively.

Mesothelioma Causes

Mesothelioma is caused by exposure to asbestos. Asbestos is a naturally occurring fibrous substance widely used in the twentieth century in a number of different industries. Popular because of its durability, fire resistance and insulating properties, asbestos was used regularly in the manufacture of thousands of products, so far in giving warnings of the dangers in the mid-1970s. It is estimated that approximately 80-90 percent of mesothelioma cases are caused by asbestos exposure.

The exact way as asbestos causes mesothelioma is not well understood, but doctors and researchers have presented many theories. What is clear is that any exposure to asbestos can be dangerous and may result in the development of asbestos-related diseases later in life.

Mesothelioma Types

There are five types of mesothelioma. Four of them are malignant cancers, and a condition is benign.

Pleural Mesothelioma: This type of mesothelioma develops in the tissue of the lungs, known as the pleura. It is the most common form of malignant mesothelioma, about 70 percent of cases are pleural in origin.

Peritoneal Mesothelioma: This form of mesothelioma develops in the tissue of the abdominal cavity, known as the peritoneal membrane. Approximately 25% of mesotheliomas are of this type.

Pericardial mesothelioma: This form of mesothelioma develops in the heart tissue, known as the pericardium. About 5 percent of all mesothelioma cases are pericardial.

Testicular Mesothelioma: This is the rarest type of malignant mesothelioma, to date, there have been fewer than 100 cases recorded. Testicular mesothelioma develops in the tunica vaginalis of the testes.

Benign Mesothelioma: The benign form of mesothelioma often develops in the pleura. This is the only form of mesothelioma which healing and recovery is a likely outcome, although it may be a precursor of asbestos-related problems in the future.

The most common symptoms of pleural mesothelioma is, shortness of breath, chest pain and persistent cough. However, some patients show no symptoms. A common sign is pleural effusion (water on the lungs).

Some symptoms of peritoneal mesothelioma include weight loss, abdominal pain and swelling and intestinal obstruction. If the cancer has spread to other parts of the body, some other common symptoms can include difficulty swallowing, swelling of face or neck, blood clotting problems, anemia, and fever.

Also the diagnosis may be difficult due to the nonspecific nature of the symptoms of mesothelioma, symptoms that often seem far less serious diseases.

The diagnostic process usually begins with a compilation of a complete medical history and work history, including any exposure to asbestos. We performed a medical examination and if you suspect a problem ask several diagnostic tests. These typically include medical imaging tests such as X rays, CT and MRI, and biopsy procedures that test samples of fluid and tissues by the presence of cancer cells. Diagnostic tests are also used to determine how far the cancer has spread, and if progress has been made elsewhere in the body.

The occurrence of this disease, sometimes referred to asbestos cancer, this fiber is the main risk factor known for this type of cancer is not indicative of a minimum threshold of exposure and medical treatment has an impact limited to the life expectancy of patients, usually 12 to 18 months.

The first signs found on clinical examination are chest pain, often associated with breathlessness and recurrent pleural effusion, usually bleeding. The latency between first exposure and the development of mesothelioma is seldom less than 20 years, often around 30 to 40 years or more. It does not seem to exist a threshold value of exposure in relation to risk of onset.

He described cases of pleural mesothelioma occurring in the family environment close to the workers exposed to asbestos, subjects were exposed due to contamination of residential premises or during maintenance of dusty clothes.

Tobacco plays a synergistic role of cofactor in the risk of developing mesothelioma.

Most often mesothelioma cancer is the result of exposure from 20 to 50 years or more ago.

Malignant Mesothelioma is a rare form of cancer that starts in the mesothelium, a membrane that covers and protects most internal organs of the body.
The mesothelium is composed of two layers, one surrounding the body itself, and the other forms a sac around it completely. A small amount of fluid is normally produced between these two layers, lubricating the motion of bodies protected.
When normal cells of the mesothelium lose control and spread rapidly, they produce mesothelioma.
The form of mesothelioma the most common is pleural mesothelioma.
It occurs in the pleura, the lining of the lungs. Other forms are peritoneum mesothelioma, reaching the peritoneum lining the abdominal cavity and pericardial mesothelioma of the pericardium.
