Mesothelioma Is An Incurable Cancer That Makes Lawyers Rich
By:frank vanderlugt
Mesothelioma is a cancer which is linked to exposure to asbestos fibers in 70 to 80 percent of cases.
The National Cancer institute defines malignant mesothelioma as "a rare form of cancer...a disease in which cancer (malignant) cells are found in the sac lining the chest (the pleura), the lining of the abdominal cavity (the peritoneum) or the lining around the heart (the pericardium)."
It is one of the most deadly cancers known to man; the average life span of an afflicted person from the time of diagnosis until death is less than 24 months.
Mesothelioma develops in approximately 3,000 United States citizens every year. Most of those diagnosed have a history of occupational exposure to asbestos, though a few have environmental or household contact. This cancer has an extremely long latency period; an exposure period of as little as one or two months can result in a mesothelioma up to 50 years later. Patients who had contact with asbestos as far back as the 1940s are now being diagnosed with this disease. In fact, the average time between exposure and the development of mesothelioma is 35-40 years.
When asbestos first came into use, its risks were unknown, and it was widely used as a fire-retardant material. Many people worked with this deadly substance, unaware that it would kill them several decades later. Workers such as bricklayers, insulaters, plasterers, electricians, mechanics, carpenters, and other tradesmen were exposed to asbestos on a daily basis as it was contained in many insulation and construction materials.
Even occassional exposure to asbestos is a health risk, and there have been many cases of mesothelioma developing in patients who only had brief contact, such as wives of asbestos-exposed workers who washed their husbands' overalls.
Due to the long latency period and vague, diffuse initial symptoms, there is often a delay in accurate diagnosis. As with many cancers, early symptoms can be mild and non-specific. Often patients present with only shortness of breath and a persistent cough; some show no symptoms at all in the initial stages, and the disease is first noticed on a routine chest X-ray. One early tell-tale sign is pleural effusion, a collection of fluid in the lungs. The right lung is affected 60% of the time, bilateral involvement being seen in 5% of cases. Less common initial complaints due to lung mesothelioma are fever, night sweats, weight loss, a raspy voice and facial swelling. Peritoneal mesothelioma can cause abdominal symptoms such as pain, abdominal swelling, nausea, weight loss, bowel obstruction, anemia and swelling of the feet. As the disease progresses, patients often develop severe cachexia (wasting).
One of the most common symptoms of mesothelioma, pleural effusion, is an accumulation of fluid between the parietal pleura, which covers the chest wall and diaphragm, and the visceral pleura, which covers the lungs. Both membranes are covered with mesothelial cells which, under normal conditions, produce a small amount of fluid that acts as a lubricant between the chest wall and the lung. Any excess fluid is removed via blood and lymph vessels, thus maintaining a balance. When more fluid is produced than can be absorbed, an effusion forms.
These effusions are called either transudates and exudates. A transudate is a clear fluid that forms not because the pleural surfaces are diseased, but because of an imbalance between the normal production and removal of the fluid. Often this is caused by congestive heart failure. An exudate, which contains many cells and proteins and is often cloudy in color, results from disease of the pleura itself, and is common to mesothelioma. To differentiate between a transudate or an exudate, a diagnostic thoracentesis, in which a needle or catheter is used to obtain a fluid sample, may be conducted.
As the volume of excess fluid increases, symptoms develop such as shortness of breath (dyspnea) , chest pain, or a non-productive dry cough. Heard through a stethoscope, normal breath sounds are muted, and tapping on the chest will reveal dull rather than hollow sounds.
A pleural effusion can be seen with a chest X-ray, ultrasound or CT scan. Since pleural effusions are often caused by congestive heart failure, the discovery of an effusion is not in itself immediately suggestive of a malignant process.
A histological examination of pleural fluid is negative in 85% of cases; a definitive diagnoses is more often is obtained by a needle biopsy or surgical biopsy of pleural tissue.
Symptomatic treatment of lung compression caused by effusion is accomplished by application of a sclerosing agent which eliminates the space between the lung and the chest cavity, a process called chemical pleurodesis. Talc is usually used, with a success rate of 95%. It can be administered either as a powder or as a slurry mixed with saline. A surgical team opens the chest wall, removes the effusion, then collapses the lung before applying the talc. Once the lung is fused to the chest wall, an effusion can no longer accumulate and compress the lung. This is strictly a palliative measure to improve the patient's quality of life, and has no effect on the progression of the disease.
Attemps to cure mesothelioma utilize surgery to remove diseased tissue, combined with chemo and raiotherapy. Several new treatment modalities are currently being investigated. These include Photodynamic therapy, which uses light of particular frequencies to target and kill cancer cells which, compared to normal tissue, display increased uptake of photosensitizing drugs; immunotherapy, which fights the abnormal cells through stimulation of the body's own immune system; and Intensity Modulated Radiation Therapy, which is a radiation treatment that attempts to target just the malignancy, thus avoiding damage to adjacent healthy cells and tissue. In addition, some success has been acheived with the chemotherapeutic drug Alitma (pemetrexed). However, despite the number of clinical trials currently underway, as of the date of this article the prognosis for mesothelioma sufferers is still extremely poor.

- 2). What are the main symptoms of Mesothelioma? By : human-health-care
The term “Mesothelioma” in medical terms is defined as form of cancer that
proliferates at a very fast rate after it has been diagnosed, which affects the mesothelial cells in the body. After detailed study of this disease by several scientists all over the world, it has been concluded that in most of the cases the reason is the direct contact with loose asbestos particles.

- 3). An Understanding Of Mesothelioma Cause By : Kirsten Hawkins
Mesothelioma cause refers to the thing or event responsible for mesothelioma cancers. Mesothelioma is a cancerous disease of the lining of abdominal organs, lungs and heart. Almost all the cases of mesothelioma disease somehow or the other are linked with exposure to asbestos particles. Exposure to asbestos particles could cause mesothelioma even if the level of exposure is very low.

What Is Mesothelioma Sarcoma?
Between the two forms of tumors of the mesothelioma, which are either benign (non-cancerous) or malignant (cancerous), the latter is more common and dangerous, popularly known as mesothelioma. Mesothelioma is characterized by its dangerous potential to spread to other parts of the body.
Types of Mesothelioma
There are three different types of Mesothelioma:
1) Ephitheliod: It affects the membranous tissue covering the internal organs and surfaces of the body.

- 10). Mesothelioma - History, Hazards and Dietary Advice By : Baymaster
History of asbestos.
There are four main types of asbestos; Amosite (brown fibers), Anthophyllite (gray fibers), white Christie, and blue Crocidolite. Chrysotile has curly fibers while the other three have rod like fibers. These fibers fragment into dust quite readily and waft into the air. They can adhere to skin or clothing and are easily swallowed or inhaled.

- 1). Increasing Awarness of Asbestos Cancer Spurs Mesothelioma Lawsuits By : Nathan T. Lynch
Mesothelioma lawsuits seem to be becoming more and more prevalent as the disease and its causes become more well-known. You may have seen commercials for attorneys advertising their services in this specialized area. Due to the fact that decades can pass before the disease rears its ugly head, it has become apparent that the companies responsible for exposing their workers to asbestos so many years ago may no longer be in business.

- 2). Diffuse Malignant Pleural Mesothelioma By : Elizabeth Morgan
Diffuse malignant pleural mesothelioma, or DMM, is a rare but highly aggressive type of cancer. It occurs in the thin layer of tissue, the pleura, lining the chest cavity and lungs. Once diagnosed with DMM, most patients do not survive beyond one year. This cancer is more common in men than in women, and in older people.
Most people with DMM have a history of exposure to asbestos; however, if they are not aware that such exposure occurred, they may be unaware that they are at risk.

- 3). Pericardial Mesothelioma: Quick Facts By : Nkeno Kapya
What is pericardial mesothelioma ?
It is a cancer caused by the inhalation of asbestos dust, and is the most rare of mesothelioma cancers. It accounts for about 5% of all cases.
Its period of latency (time it takes for the symptoms to show) is approximately 30-50 years. Symptoms are similar to other diseases such as pneumonia whilst in the early stages.

- 4). What is pericardial mesothelioma ? By : Nkeno Kapya
Mesothelioma is a cancer of the epithelium that lines the lungs, the abdomen, or the heart. Pericardial Mesothelioma is the cancer of the lining of the heart, known as the pericardium, hence the name pericardial mesothelioma.
This rare form of mesothelioma accounts for small percentage of all cases, roughly 5%. The pericardium has an extrememly important role as it protects the heart from any damage.

- 5). How do you treat pericardial mesothelioma ? By : Nkeno Kapya
Of all the cancers caused by asbestos dust (mesothelioma), pericardial mesothelioma is the most rare, accounting for a fraction of all cases (5%). It is a cancer that grows on the pericardium (the lining of the heart). This is a delicate 'film', and any infection on the pericardium can have deadly consequences.
Once an individual has been diagnosed with pericardial mesothelioma they are offered three different treatment options.

- 6). Mesothelioma Lawsuits By : Bob Alderton
Mesothelioma Lawsuits are not unique: As long as there have been environmental factors with impact on our health as well as a legislative system, people have filed lawsuits if the impact has been of a negative kind. Mesothelioma is a cancer primarily focused on the cells surrounding the lungs. This cancer has been associated exclusively with the exposure to asbestos which was commonly used in industrial and residential uses up until the late 1970's.

- 7). The Facts about Mesothelioma Cancer By : Heather Colman
What is Mesothelioma Cancer?
Mesothelioma cancer is an extremely rare cancer form that is only found in the mesothelium. This form of malignancy generally affects those people who have been exposed to a situation where asbestos is present, typically those who have worked in buildings where it was used as a fire retardant..
What happens when a person has Mesothelioma Cancer?
This type of cancer directly affects the mesothelium and causes abnormal cells.

- 8). What Are The Risk Factors For Malignant Mesothelioma? By : Mick Marshall
A risk factor is anything that increases your chance of getting a disease such as cancer. Different cancers have different risk factors. For example, exposing skin to strong sunlight is a risk factor for skin cancer. Smoking is a risk factor for cancers of the lung, mouth, larynx, bladder, kidney, and several other organs. Individuals exposed to asbestos should be encouraged to avoid tobacco exposure because together the risk for lung cancer is significantly higher than from smoking without a history of asbestos exposure.
