Introduction

Mesothelioma is a cancer which affects the tissue which surrounds and protects various organs in the body. This tissue is called the Mesothelium, and Mesothelioma causes it to become abnormal, divide without control, and invade and damage nearby organs. The most common form is pleural mesothelioma which affects the sac that lines the chest cavity and protects the lungs (the pleura). Other forms are peritoneum mesothelioma (which affects the abdominal cavity) and pericardium mesothelioma (affecting the lining around the heart). The tumours can be either benign (non-cancerous) or malignant (cancerous) although they are most often malignant.

Causes

Mesothelioma is caused by the inhalation of asbestos, a fibrous carcinogenic. These fibres lodge themselves in the lining of the lung affecting the mesothelial cells. Sometimes they cause scarring of the lungs (which is called asbestosis) but this is not cancerous. They can, however, trigger tumour growth between 20 to 50 years after they are inhaled (the average is 35 to 40 years). Asbestos fibres which are swallowed can reach the lining of the abdominal cavity where they play a part in causing peritoneal mesothelioma.

It is generally the case that the longer or more intense the exposure to asbestos the more likely Mesothelioma is to occur. However, there are cases of people getting Mesothelioma years after having worked with it for just a few months. The families of asbestos workers are also at risk as they would possibly have been exposed to asbestos fibres on the clothing of their loved ones.

The dangers of asbestos are now well known, but this was not always the case. Before the 1970s asbestos was a primary insulating material with little or no control in its use or handling. The resulting increase in cases of Mesothelioma is a direct cause of these past practices.

Symptoms

Mesothelioma is often advanced before symptoms occur. This means that the prognosis is not usually very good, with the average survival time for all stages of Malignant Mesothelioma being about one year. Symptoms resemble pneumonia, which coughs, breathing difficulties and abdominal pain being common.

Treatments

Mesothelioma can be treated by chemotherapy, radiotherapy or surgery, or a combination of the three.

Surgery
Extra pleural pneumonectomy is where the entire lung and a portion of the lining of the chest, the diaphragm, and some or the entire sac which surrounds the heart is removed.

Wide local excision targets and removes the cancer and a limited amount of the healthy tissue surrounding the cancerous region.

Pleurectomy and decortication removes part of the covering of the lungs, as well as the lining of the chest and portions of the outside covering of the lungs.

Pleurodesis uses a blend of chemicals and/or drugs to create an intentional scar between the layers of the pleura. Post surgery, the space created by the scar must be drained, using either a catheter or chest tube, and is then filled with a chemical which inhibits the accumulation of fluid in the pleura cavity.

Radiation Therapy
Radiation Therapy uses high energy x-rays to kill cancer cells.

In External radiation therapy a machine emits radiation in a targeted stream at a certain portion of the body.

Internal radiation therapy uses needles, seeds and catheters to place radioactive substance directly on or near the cancer.

Chemotherapy
Chemotherapy uses cancer targeting drugs to stop the cells them from dividing and thus prevent their growth.

Mesothelioma is a type of cancer that is found usually among men who are advanced in years. This type of cancer is caused from the effects of exposure to asbestos ad as a result affects the membranes of our vital organs such as the heart and lungs. Mesothelioma cancer is not very easy to diagnose due to the fact that the symptoms this type of cancer presents are very similar to other diseases that are much more common.

Pleural Mesothelioma

Pleural Mesothelioma is the most common form of this disease and as a direct result accounts for around 75% of all cases of this disease. This type of cancer (Pleural Mesothelioma) attacks and affects the lining of the lungs and presents common symptoms such as shortness of breath, coughing and wheezing, chest pains, difficulty in swallowing and even weight loss. As we have said, these symptoms are very common to other diseases but anyone who has any of them we would strongly suggest consulting their doctor right away just to be on the safe side.

Peritoneal Mesothelioma

One of the less common forms of Mesothelioma is called Peritoneal Mesothelioma and this type of cancer affects the abdomen. Peritoneal Mesothelioma cancer affects the abdominal lining and frequently found in people who have been exposed to asbestos and accounts for around 20% of all Mesothelioma cases. Symptoms of Peritoneal Mesothelioma are as follows: abdominal pains, abdominal swelling, weight loss, loss of appetite, weakness and nausea.

The importance of early diagnosis

People who have worked with asbestos or have been exposed to the substance are at risk of developing the disease. One of the most important things that we should remember when dealing with this type of cancer is speed. Early diagnosis of the disease is of utmost importance so that it can be treated quickly. With time being of importance when dealing with Mesothelioma, the earlier it is discovered the more chance we have of success in its treatment.

What are Mesothelioma Cancers?

Mesothelioma cancers are the cancers that spread in the
mesothelium tissues. Mesothelium in general is the name of
tissue that forms lining of different body organs such as heart,
lungs, abdomen and reproductive organs. The lining around
abdominal organs is known as peritoneal membrane. Lining around
lungs is called pleural membrane while the lining around heart
is called pericardium.

These linings perform two functions. They protect the internal
organs by producing a lubricating fluid and to allow the smooth
movement of the internal organs. Mesothelioma cancers are the
cancers affecting these membranes. The names of the cancers
depend on the tissue or linings they affect. Peritoneal
mesothelioma, pleural mesothelioma and pericardial mesothelioma
are the names of cancers of linings of abdomen, lungs and heart,
respectively. Pleural mesothelioma is the most common of all
mesothelioma cancers and is found in 70 % of the mesothelioma
patients. Peritoneal mesothelioma constitutes 10% to 20% of the
mesothelioma patients while third type pericardial mesothelioma,
is rare.

Symptoms of Mesothelioma Cancers

Symptoms of mesothelioma cancers are same as of other common
diseases. It makes diagnosis mesothelioma cancers a difficult
task. Pain and swelling in abdomen, weakness, loss of weight,
loss of appetite and nausea are some symptoms of peritoneal
mesothelioma. Symptoms of pleural mesothelioma are persistent
cough, difficulty in breathing, weight loss, loss of appetite,
weakness, chest pains, lower back pains and difficulty in
swallowing.

History

History of mesothelioma cancers goes back to as far back as
1900s. It took about 60 years to gather sufficient information
about these mesothelioma cancers. By the end of sixth decade of
last century, experts could conclude that exposure to asbestos
particles is the reason behind the disease. J. C. Wagner was
first researcher to report 32 cases of mesothelioma cancers and
confirmed its association with asbestos exposure.

One alarming fact about the mesothelioma cancers is its extended
latency period. These cancers may remain asymptomatic in the
body for even up to 50 years. Chances of survival for
mesothelioma patients are rare and the average survival period
after diagnosis is not more than 12-24 months. Surgery if
diagnosed early, chemotherapy and radiation therapy are some
common treatments for all types of mesothelioma cancers. People
suffering from mesothelioma cancers can file lawsuits to recover
damages for medical expenses and other damages. They can file
the lawsuits against the persons and companies responsible for
causing asbestos exposure

Cancer takes on many forms and results from many causes. Some cancers are preventable. Some forms of cancer have a good prognosis. The type of cancer that is the focus of this article is called Mesothelioma and it is preventable. If someone develops mesothelioma, typically the prognosis is poor and families need to seek help from a mesothelioma lawyer.

Mesothelioma is caused by exposure to asbestos and the legacy of mesothelioma is a disturbing one. Thousands of people unduly suffer from the effects of asbestos exposure and many more have wrongly died. The hazardous effects of asbestos became know in the 1920s but corporations, who were using asbestos, did not tell their employees of the danger nor did they use alternative materials.

Thousands of persons were unnecessarily exposed to asbestos and as a result many developed mesothelioma in their later years. If you, or anyone you know, have mesothelioma contact a mesothelioma lawyer to help you receive compensation if you were wrongly exposed to asbestos.

If you know someone who died from mesothelioma, it is important that their family contact a mesothelioma lawyer who can recommend whether a mesothelioma lawsuit may result in compensatory benefits.

Mesothelioma attacks what are called mosothelial cells of an organ. The most common organ cells affected by mesothelioma are those in the lungs, heart or abdomen. Pleural mesothelioma is the most predominant type of mesothelioma and it presents as an extremely virulent variety of lung cancer. Pleural mesothelioma is separated into two explicit categories. The first type is called diffuse and malignant (cancerous) and the second type is known as benign (not cancerous).

Malignant mesothelioma is a life-threatening rare condition accounting for almost 75% of all the mesothelioma cases. Malignant mesothelioma must be treated aggressively as it is a malignant type of cancer.

Not only for this reason but, also because more often than not, by the time it is has been diagnosed, the disease has moved into an advanced stage of cancer. The diagnosis of mesothelioma can only be made definitively by taking a biopsy and conducting a pathological analysis.

As the pleural mesothelioma tumor spreads over the pleura, (a thin membrane that covers the outside of the lungs) it produces thickening of this membrane. As the thickening progresses, a restraining type of girdle effect takes place.

As the pleural membrane becomes thicker and more restrictive, the lungs become more restrained and start to diminish and become smaller. The ultimate result of this progression is that the lung(s) are less capable of performing their functions.

One of the first signs someone will begin to experience is shortness of breathe. This will initially be noticeable when they put forth energy or effort in actions such as light exercise, making a bed, and yard work etc.

As the pleural mesothelioma grows and the lung(s) become less functional, the difficulty in breathing expands to occurring when the patient is involved in activities requiring even less exertion than light exercise. Eventually the pleural mesothelioma patient will experience shortness of breath even when lying down, sitting in a chair, and/or resting.

The tumor is constricting the lungs as it moves inward and as it expands outward, to affect nearby tissue of the chest cavity and ribs, it more than likely will create an excessive level of pain.

The second type of mesothelioma mentioned above is referred to as peritoneal. The tumor associated with form of mesothelioma affects the peritoneum membrane that lines several abdominal organs. Peritoneal mesothelioma is not as rare as pleural mesothelioma but it presents more aggressively and as a results in a reduced life expectancy.

As with all cancers, peritoneal mesothelioma can be benign or malignant. Peritoneal mesothelioma takes years to develop and it is generally discovered by sheer chance and prior to symptoms beginning.

Typically the symptoms of peritoneal mesothelioma include: abdominal pain, a generalized weakness, poor appetite with eventual lose of weight, nausea and vomiting, and swelling of the abdomen.

The symptoms of peritoneal mesothelioma progress slowly and as time passes they become more and more severe. As with pleural mesothelioma, there is no cure and the prognosis is affected by the tumor size and stage, the type of tumor cell, and the response to treatment.

Treatment options for both types include: chemotherapy, radiation, surgical intervention, and intra-operative photodynamic therapy; which is the latest drug and light treatment used in the early stages of mesothelioma.
