Malignant Mesothelioma

Malignant mesothelioma is a rare form of cancer that affects the mesothelial cells around the heart, lungs or abdominal organs. The most common type of mesothelioma is the one which affects the pleura, the thin membrane between the lungs and the chest cavity. This type of the disease is known as Pleural Mesothelioma, and sufferers can experience symptoms which include: shortness of breath, breathing difficulties, persistent coughing, chest pains, weight loss, and trouble swallowing.
Peritoneal Mesothelioma is another form of this disease but is not as common as Pleural Mesothelioma. This type of the disease affects the peritoneum membrane of the abdomen. These tumors can also be found in the stomach and abdominal organs. Sufferers of Peritoneal Mesothelioma can experience symptoms which include: stomach pains and abdominal swelling, nausea, loss if appetite, vomiting, bowel obstruction, and blood clotting abnormalities.
The third and the rarest type of mesothelioma is Pericardial Mesothelioma, which affects the tissue and cavity surrounding the heart. Patients of this type of the disease may experience symptoms such as shortness of breath, chest pains, persistent coughing and palpitations.
Malignant mesothelioma is a fatal disease caused by exposure to asbestos. A form of cancer, this disease can affect the sac lining, the chest or the abdomen. An unusual aspect about this disease is that it does not manifest itself for years following the asbestos exposure – in fact, the average manifestation time is 35-40 years later, and in some cases even 50 years later.
In previous years, asbestos was widely used in many places. Many people worked with this deadly material, unaware that several decades later it would be the death of them. Workers such as insulaters, plasterers, electricians, mechanics, bricklayers, carpenters, and other tradesmen were exposed to asbestos on a daily basis as it was contained in many insulation and construction materials.
However, it is not only those that were regularly exposed to asbestos that are at risk. There have been many cases of mesothelioma manifestation in people that were only exposed to asbestos for a short period of time. In fact, the disease has even been known to affect people who have had only minimal contact, such as wives that used to wash their husbands overalls after they had worked with asbestos.
The long latency period attached to mesothelioma means that the symptoms of this disease can take many years to manifest, making both diagnosis and effective treatment very difficult. And even when the symptoms do become evident, which can take several decades, the symptoms are so generalised and non-specific that they could be put down to any number of more common diseases. This makes it hard for even experienced doctors to make a quick and conclusive diagnosis with mesothelioma patients. The symptoms of this disease can often be confused with pneumonia during its early stages.
Some of the most common symptoms of pleural mesothelioma (which is the most common form of the disease) are shortness of breath and chest pains. This may be accompanied by a persistent cough, and all of these symptoms stem from the build up of fluid between the lining of the lung and the chest cavity. This is known as pleural effusion. This type of the disease starts in the chest cavity and can then spread to other parts of the body. Pleural mesothelioma sufferers may also begin to display severe breathing difficulty, weight loss and fever as well as trouble swallowing and even swelling of the face and neck. Some patients may also develop a rasping voice and start coughing up blood. However, there are other patients that may not show any significant symptoms at all.
The symptoms for patients who suffer from peritoneal mesothelioma (a rarer form of the disease) are slightly different. This type of the disease starts in the abdomen and can spread form there. Patients of peritoneal mesothelioma can display abdominal pain and swelling, nausea, loss of appetite and vomiting. They can also suffer breathing problems, and chest pain in addition to these symptoms. These symptoms result from tumors that lean against the abdominal wall. Bowel obstruction, anemia, fever and problems with blood clotting may also affect peritoneal mesothelioma patients.
The rarest form of this disease is pericardial mesothelioma, which starts in the cavity surrounding the heart. With pericardial mesothelioma, the tumors grow in the tissues that surround the heart and can spread from there. Pericardial mesothelioma sufferers may experience chest pain, shortness of breath, persistent coughing and palpitations.
