Mesothelioma is a form of cancer caused due to exposure to asbestos. Mesothelioma mainly affects the mesothelium which is a protective lining covering all internal organs of the body. Mostly, it originates in the pleura, which is the between the outer part of the lungs & the chest cavity. Mesothelioma may also attack in or the lining of abdominal cavity (peritoneum) or the sac which surrounds heart (that is, pericardium).

It has been observed that person having <a rel=”nofollow” onclick=”javascript:pageTracker._trackPageview(‘/outgoing/article_exit_link’);” href=”http://mesotheliomastraight.net”>Mesothelioma</a> must have worked on a job where he may have inhaled asbestos particulates, or he might have been exposed to asbestos dust and fiber in any other way. It might be caused just by washing cloths of some family member handling asbestos regularly. But, unlike lung and oral cancer, there exists no link between mesothelioma & smoking. It is an unbelievable fact that an exposure of 1 or 2 months could result in mesothelioma 30 or 40 yrs later and for some, as much as seventy years later. People exposed in the 1960s and ’70s are now diagnosed of mesothelioma due to the long latency of asbestos deposit.

On suffering from <a rel=”nofollow” onclick=”javascript:pageTracker._trackPageview(‘/outgoing/article_exit_link’);” href=”http://mesotheliomastraight.net”>Mesothelioma</a>, patient may have breathlessness, slight pain in the chest and cough, while peritoneal mesothelioma causes patient to lose weight and pain in the abdomen. Peritoneal mesothelioma causes obstruction in bowel-area, abnormal blood clotting, anemia, and may also cause fever. In case the cancer spreads to other parts of the body, it may cause pain, troublesome swallowing, or swelling in neck and face. Mesothelioma can only be diagnosed from biopsy by pathological examination If further examination is warranted, more tests may be done. Mesothelioma has three kinds of treatments. First one involves surgery, that is, to take out the cancer. Secondly, the deadly radiation therapy to kill cancer causing cells. The third is the chemotherapy, in which drugs are inserted in body to fight cancer.

Mesothelioma is the growth of malignant cells in mesothelium, the thin membrane covering the body’s internal organs. This mesothelium lining covers the pleural, peritoneal and pericardial cavities. Pleura is a membrane covering the lungs and it is the most common location where mesothelioma cancer occurs also known as pleural mesothelioma. Peritoneum, the protective covering that lines the abdominal cavity may also develop malignant tumors and cause peritoneal mesothelioma.

Mesothelioma is one of the rarest cancers in the world that is caused only by exposure to asbestos. Its exposure can be direct, by inhalation of asbestos or indirect exposure in which the asbestos particles are inhaled from the clothing, hair, equipment or other articles that were previously exposed to asbestos.

Causes of Mesothelioma

Asbestos is a naturally occurring fibrous mineral that is mined in different parts of the world due to its wide utility in various industries. However, it is a deadly carcinogen too and a mojor cause of mesothelioma and asbestosis.

Asbestos fibers are known to cause cancer of the mesothelium. Asbestos is the fibrous form of several minerals and hydrous silicates of magnesium found under ground. There are 3 types of asbestos, the blue one, the while one and the brown one. Of all these 3 types, the blue one also called amphibole, long and thin in structure is more carcinogenic than white or chrysolite asbestos or the brown one known as amosite.

However, in some cases the brown asbestos has also been found to cause mesothelioma. And it is for this reason that people exposed to asbestos even for a short period are vulnerable to the disease.

Pleural Mesothelioma

Asbestos fibers are very fine and easily make their way to the lungs where they settle down in the parenchyma of the lung and penetrate the pleura that later develops malignant mesothelial plaques.

Pleura, which anchors lungs to the chest cavity, is itself a double-layered membrane. The inner layer called visceral pleura surrounds the lungs, while the outer one, known as parietal pleura, forms the lining of the pleural or chest cavity. The two pleural layers are filled with a fluid that helps them to slide over each other as we breathe. As the disease progresses, the delicate pleural membranes thicken and press the lungs. A fluid secreted by the malignant cells, pleural effusion, may also collect between visceral and parietal pleurae that causes problem in breathing and other complications.

Peritoneum Mesothelioma

The asbestos fibers may also cause cancer in the peritoneum, known as peritoneal mesothelioma. This leads to thickening of the membranes surrounding abdominal organs and collection of a fluid, ascites in the abdominal cavity making it swell.

Though it is yet not clear how peritoneal mesothelioma develops, it is believed that from lungs, the asbestos fibers are transported to abdomen and its organs by the lymphatic system or they may be deposited in the gut through saliva contaminated by the asbestos fibers.

Pericardial Mesothelioma

This is the rarest type of mesothelioma cancer that comprises of only 5% of all the mesothelioma cases. Like other types of mesothelioma cancer, pericardial mesothelioma is also caused by the inhalation of asbestos dust and fibers. The lining of the chest cavity which protects the heart is known as pericardium. It is provided with a natural fluid or mucous that provide continuous lubrication to the heart so that it can work properly and perform its functions.

It is a very deadly disease that destroys the tissues around the heart and diminishes the survival chances of the patient. As the asbestos particles settle further into the lining of the chest or pericardial, the cancer spreads in the body. It destroys the heart tissues and muscles that is very hazardous to life and proves fatal for the patient.

Mesothelioma is relatively a newer disease and its causes have been under study for several years now. It is estimated however that every five out of six cases of mesothelioma are because of the patient’s unprotected exposure to asbestos. Asbestos was previously excessively used for the purpose of making construction materials, brake pads and plenty of everyday things but now, since other material have been discovered and are relatively less harmful than asbestos, one suffering from mesothelioma can sue the employer for having contracted the disease.

One other cause for mesothelioma other than exposure of the patient to asbestos is the genetic mutation of cells. According to most mesothelioma treatment centers, the causes for mesothelioma can be linked with the genetic mutation that converts healthy cells into cancer cells. These cancer cells multiply faster than normal cells and unfortunately do not degenerate at the same rate as do normal cells. Thus these cancer cells accumulate to form tumours which are capable enough to invade the tissues of the body and spread over wider areas. The collaboration of a number of factors appears to cause this genetic mutation and lead the patient to suffer from cancer mesothelioma. These factors include the environment of the individual who is suffering from mesothelioma, his overall health condition as well as the lifestyle choices he makes such as whether to smoke or whether to not.

Also as we know already, exposure to asbestos initiates this genetic mutation. When the asbestos fibers lodge in the lungs or other internal organs, the process of genetic mutation is initiated. About 2500 to 3500 people are diagnosed with mesothelioma cancer in the United States each year alone and most of these people have exposure to asbestos in their past. However even today the exact causes for mesothelioma is yet to be found and we realize how necessary it is to help fight the devastating state of the disease.

In the United Kingdom, large scale studies and experiments are being conducted to find out the causes of mesothelioma. Hopefully this initiative will help to find a successful solution to the problem of this vague disease. In a study that was conducted on animals, the Simian Virus (SV40) was understood to be the cause of mesothelioma. There were some vaccines during the 1950s and 1960s, especially some polio vaccines that were contaminated with this SV40 virus. However no definitive association between SV40 and mesothelioma has been discovered.

On the other hand, there are a number of cases of mesothelioma in people who underwent tests of X-ray imaging and thorium dioxide being used in the process. This is a reason why these specific X-ray tests have not been in use for many years now because a tentative association had been discovered between cancer and thorium dioxide. If you think that you may be suffering from a symptom that needs to be checked immediately because there are chances you might be the victim of mesothelioma, visit a mesothelioma treatment center as soon as possible for more information.

Peritoneal mesothelioma is a rare form of a rare type of cancer. Mesothelioma is a cancer that’s caused from exposure to asbestos. Less than three thousand people are diagnosed with this type of cancer in the US each year. Of those, between ten and twenty percent have peritoneal mesothelioma.

Peritoneal mesothelioma is an aggressive cancer that grows in the peritoneum, which is a layer of tissue that essentially covers the abdominal area. Other types of mesothelioma form in the tissue that surrounds the organs like the heart and lungs.

This cancer is caused by inhaling asbestos. The fibers don’t break down in the body like many other ingest or inhaled substances. They never leave once inhaled, and lodge between mesothelial cells, which gives this type of cancer its name.

Because today we know that asbestos is dangerous and deadly, it has to be removed from public buildings and we’re warned about having it removed from our homes. Special hazardous materials handlers, known as hazmat workers, have to remove asbestos while wearing protective suits and using special equipment to keep it from getting on their skin or into the air.

Peritoneal mesothelioma, like other forms of asbestos-caused cancer, will often not show up for several years after the initial asbestos exposure. It can even take 2 to 5 decades before symptoms appear. But once the exposure happens, and the asbestos fibers lodge between the cells, they cause irritation and inflammation. This causes the cells to grow abnormally and they become cancerous. As the cells continue to grow and divide in this warped way, the peritoneum thickens, and the cells eventually form a tumor or often several tumors.

Symptoms can include things like fever, sweating at night, diarrhea, constipation, stomach pain, stomach swelling, weight loss, nausea, vomiting, anemia, constant fatigue, and in many cases the lumps growing on the abdominal wall can be felt beneath the skin. Since most of the symptoms are symptoms of a variety of ailments, having them does not mean you have peritoneal mesothelioma. X-rays can confirm or help rule out the disease, as can other testing like tissue or fluid biopsies.

This type of cancer has often been present in the body so long before it’s discovered, that it’s typically very hard to treat. By the time it’s discovered, it’s almost always last stage cancer, which means it has spread over the affected area and often beyond it. Surgery can be performed to remove the obvious cancer, and then chemotherapy and radiation are used to kill any remaining cancer cells or at least slow its growth. There is no cure, but these measures can bring temporary relief from the pain of the cancer and prolong the patient’s life.

A chemotherapy treatment known as intraperitoneal chemotherapy can sometimes be used to help fight the cancer. In this treatment, the medicine is injected into the peritoneum instead of the bloodstream, to fight the cancer at its source. This treatment and clinical trials of new treatments often give peritoneal mesothelioma patients the best chance at longer more comfortable lives than standard treatments alone.

Ninety percent of all mesothelioma cases are caused by asbestos exposure. This cancer affects the protective lining that covers many of the body’s internal organs known as the mesothelium. The areas of the lining most often affected are the lungs and abdomen.

Asbestos is a natural fiber that is strong, flexible, and highly durable. It was used in insulation and household appliances for years because of it’s ability to resist heat and chemical damage. The fact that asbestos causes mesothelioma and other chronic lung conditions was unknown until the 1960s.

Asbestos fibers are tiny, and when asbestos is mined or disturbed in any way, these fibers are released into the air. They then make their way into the lungs of anyone who is exposed, where they cause inflammation and the formation of scar tissue. This damage can then lead to mesothelioma, and it is this damage that is the most common cause of mesothelioma. The fibers imbed themselves into the lungs, working their way through to the membrane that surrounds the lungs and causing this specific type of cancer.

Mesothelioma in the abdomen is often caused when the fibers make their way into the mouth, are swallowed, and move through the digestive system. Asbestos can also cause other forms of chronic lung disease and respiratory problems such as difficulty breathing.

Construction workers, those who work in or live near asbestos factories, miners of asbestos, and anyone working in industries where asbestos is used are the most likely to develop mesothelioma. While asbestos is no longer widely used, mesothelioma may not show up for as long as 60 years after exposure, so anyone who thinks they may have come into contact with asbestos should regularly be checked for mesothelioma.

Mesothelioma does develop without asbestos exposure in rare cases, although the exact cause of these cases is not known. Since it was discovered that asbestos causes mesothelioma, most asbestos insulation and building materials have been removed from the market, and many buildings have been purged of their asbestos. Because asbestos is the most common cause of mesothelioma, exposure to the fiber should be avoided, and anyone who has reason to come into contact with asbestos should take extra precautions to avoid inhalation or other direct exposure.
