Mesothelioma is an uncommon disease that causes malignant cancer cells to form within the lining of the chest, abdomen, or around the heart. Its primary cause is believed to be exposure to asbestos.

Malignant mesothelioma is also known as asbestos cancer or simply "meso." Mesothelioma causes cancerous cells to develop in the body's mesothelium, where they can spread to and damage vital organs and tissue. These malignant cells can also metastasize to other regions of the body. Mesothelioma is very difficult to diagnose and responds poorly to most treatment modalities, accounting for a poor prognosis.

The disease derives its name from the mesothelium, a sac-like membrane that protects most of the body's internal organs. It is divided into two distinct protective layers of cells: the visceral (the layer directly surrounding the organ) and the parietal (a sac around the body cavity). By releasing a lubricating fluid, the mesothelium allows the organs to move more freely within the body cavity; for example, the contraction and expansion of the lungs. The mesothelium is also referred to according to where it is located in the body: pleura (chest), peritoneum (abdomen), and pericardium (heart).

Over two-thirds of all mesothelioma cases begin in the pleura region. Pleural mesothelioma spreads through the chest cavity, occasionally developing in the lungs as well. The disease most commonly causes pleural effusion, an excess build-up of fluid inside the chest cavity. This excess fluid increases pressure on the lungs and restricts breathing. In addition, malignant cells can cause the pleural lining to thicken and restrict the breathing space even further.

Peritoneal mesothelioma is the second most common form of the disease, accounting for less than 30% of all cases. Malignant cells form in the peritoneum, affecting the abdomen, bowel, liver, and spleen. Similar to pleural mesothelioma, the disease also causes a build up of excess fluid in the abdominal cavity. Normal bodily functions, such as digestion, can be hindered by the obstruction of organ movement.

Very rare forms of mesothelioma occur in the pericardium, as well as the mesothelium of the male and female reproductive organs. Cystic mesothelioma of the peritoneum, another rare form of the disease, occurs predominantly in women and is more benign in nature.

Malignant mesothelioma takes the form of one of three cell-types: epithelioid (50% to 70% of cases), sarcomatous (7% to 20% of cases), and biphasic/mixed (20% to 35% of cases). Of these cell-types, epithelioid mesothelioma carries the most favorable prognosis, followed by biphasic, and finally sarcomatous (very aggressive).

Mesothelioma remains relatively uncommon in the United States, with approximately 2,500 new cases reported annually. The incidence rates are much higher in Western Europe (over 5,000 cases reported annually). These numbers are expended to climb dramatically over the next 20 years. Older males (median age 60 at diagnosis) are three to five times more likely to develop mesothelioma than women. This is most like do to male predominance in those professions with an increased risk of asbestos exposure.

Approximately 80% of all mesothelioma patients have a history of asbestos exposure. The majority of these patients were employed in an industry that involved the use of asbestos in some fashion. In addition to occupational exposure, household exposure of family members is not uncommon. An exposed individual can carry the asbestos particles on their clothing, skin, and in their hair when they return home, resulting in paraoccupational exposure. Even brief exposure to asbestos, as little as one to two months, can result in long-term consequences. Although the dangers of asbestos have been known for decades, the long latency period of mesothelioma (30 to 40 years) means that majority of patients were already exposed as far back as the 1950s. It is estimated that up to eight million Americans have already been exposed. Several industries, in particular, show a higher incidence of asbestos exposure:

In 1969, the first successful mesothelioma lawsuit was filed, recognizing a manufacturer’s duty to warn workers of the health risks of dealing with asbestos.

First asbestos lawsuit filed
In that case, Clarence Borel filed a claim against several asbestos manufacturers after he received a mesothelioma diagnosis. The court’s opinion extended strict product liability to asbestos diseases caused by the use of this once commonly used product .

Thousands of asbestos lawsuits followed in the next decade, and injuries caused by exposure to the deadly mineral became the nation’s largest area of product liability litigation.

Johns-Manville goes bust
In 1982, the Johns-Manville Corporation became the largest American company ever to file for bankruptcy after court documents proved that it had a history of hiding evidence that associated asbestos exposure to mesothelioma symptoms.

Mesothelioma Lawyer Mesothelioma is getting mentioned ever so prominently in American courts and on television from mesothelioma lawyers. It is an extreme form cancer form that takes its toll on the human lungs. It affects primarily the lung lining although it may also affect the abdomen (pleural and peritoneal mesothelioma respectively). The primary cause of this ailment is asbestos exposure which details introduction of carcinogenic mineral fiber although easily preventable. There are many people who get exposed to asbestos in their places of work and a backing to go to court with a mesothelioma lawyer and file a lawsuit upon the asbestos manufacturer. As the numbers of people exposed to asbestos in America increases, the main facilities leading in exposure rates include; construction sites, shipyards, automobile garages, ships for the Navy and Factories. There is also a high risk of the exposure in old homes and commercial buildings. There is a rich background on the dangers of asbestos which has been well known by manufacturers although not publicized. This failure of communication has contributed to the asbestos tort where mesothelioma attorneys have filed numerous lawsuits to get compensation for unnecessary cancer. The companies that dealt in asbestos were faced by a rude surprise from the 1960s where consumers and employees alike filed numerous mesothelioma lawsuits against them. The malicious trend was brought up in many cases by different juries and it became …

Malignant Mesothelioma is a rare form of cancer that affects the thin cell wall lining of the body's internal organs and structures. This lining is known as the mesothelium. Malignant mesothelioma has three known varieties. They are malignant pleural mesothelioma, malignant pericardial mesothelioma, and malignant peritoneal mesothelioma. Pleural mesothelioma occurs in the pleura, the lung's lining. Peritoneal mesothelioma occurs in the peritoneum, the abdominal cavity wall. And pericardial mesothelioma occurs in the lining of the hearth, known as the pericardium.

Mesothelioma is known only to be caused by asbestos exposure. Asbestos is a nature, yet toxic mineral that was used commonly in heavy industry. Microscopic asbestos fibers enter the body through the lung or ingestion. Once inside, the durable fibers are unable to be broken down or expelled by the body, causing a harmful inflammation and scarring of the mesothelium. This scarring lays the groundwork for malignant mesothelioma and other respiratory conditions, such as asbestosis.

There is a great deal of latency associated with asbestos exposure and the onset of mesothelioma. Often patients will not encounter mesothelioma symptoms until 30-50 years following exposure to asbestos. In many cases, those diagnosed with mesothelioma are not those who were directly exposed to asbestos in a jobsite setting. Spouses and children of those exposed to asbestos who frequently came into contact with the fibers on the clothing or person of those exposed have also developed malignant mesothelioma as a result



Malignant mesothelioma prognosis is poor, as often the disease will be diagnosed in its later stages after symptoms have appeared. However, there are several treatment options for the management of the cancer. Among these are mesothelioma chemotherapy, radiation therapy, and surgical resection. Chemotherapeutic and radiation therapy methods are more likely but surgery is often an option for those whose disease is diagnosed early enough.

More aggressive therapies are now possible for patients with mesothelioma diagnosed in its earlier stages. For instance, extrapleural pneumonectomy is now possible in many pleural mesothelioma patients who are deemed eligible for aggressive surgery. Extrapleural pneumonectomy involves the removal of the entire affected lung, the pericardium, the pleura, and the diaphragm. This aggressive surgery is performed frequently in early stage mesothelioma patients by Dr. David Sugarbaker at the Brigham and Women's Hospital in Boston, MA.


Patient's who are eligible to receive an aggressive surgery, like an extrapleural pneumonectomy, will have a far more favorable prognosis than those diagnosed with advanced stage inoperable disease. However, there are treatment options for nearly all mesothelioma patients. Chemotherapy cocktails such as the use of Alimta® in conjunction with Cisplatin, as well as numerous other clinical trial being carried out give mesothelioma patients the ability to slow the advance of the disease and extend survival rates.

Malignant pleural mesothelioma is the most common type of mesothelioma and occurs in the mesothelial membrane surrounding the chest cavity and lungs. Pleural mesothelioma, because it is more common than other varieties of the malignancy, has had more research invested in it. Pleural mesothelioma represents approximately 70% of all mesothelioma diagnoses.Malignant peritoneal mesothelioma is less common than pleural mesothelioma and represents approximately 15-20% of all mesothelioma diagnoses. Peritoneal mesothelioma occurs in the lining of the abdominal cavity in the membrane surrounding the organs of this region. Like pleural mesothelioma, peritoneal mesothelioma is known only to be caused by exposure to asbestos.

Malignant pericardial mesothelioma is among the rarest of all known malignancies, and represents less than 10% of all mesothelioma diagnoses. Pericardial mesotheliomas occur within the mesothelial lining of the heart. Pericardial mesotheliomas, like those of pleural and peritoneal varieties, are associated with asbestos exposure. Pericardial mesotheliomas differ from the pleural variant in that they are known to occur in younger individuals. While surgery is seen as the preferred method of treatment, mobidity and mortality are almost certain given the region in which the tumor is located.

n 2005, at the age of 36, and only three months after giving birth to a beautiful daughter Lily Rose, Heather Von St. James was diagnosed with pleural mesothelioma. Upon learning of this life-altering diagnosis, Heather, together with her husband Cameron, embarked upon a search to find the best mesothelioma treatment care available. Their search eventually led them to Dr. David Sugarbaker, a renowned mesothelioma surgeon at the Boston based Brigham and Women's hospital. Dr. Sugarbaker recommended a relatively new surgical procedure called extrapleural pneumonectomy, a groundbreaking treatment option offered through the International Mesothelioma Program. Although there were some risks associated with the procedure, it also carried promise for the best possible outcome. Heather, with full support from her husband and family, agreed to have the surgery.

Today, Heather Von St. James is a seven year mesothelioma cancer survivor and continues to provide unending inspiration to mesothelioma victims around the globe. She carries out her mission to be a beacon of hope for those afflicted with mesothelioma by sharing her story of faith, love and courage both as a keynote speaker at conferences and through social media forums.

Melanie also assists in social media outreach in her efforts to spread awareness. In her spare time, you can find Melanie trying new vegan recipes, on her yoga mat, or spending time with her family.

A pleurectomy / decortication (P/D) is an operation for mesothelioma that removes the involved pleura and frees the underlying lung so that it can expand and fill the pleural cavity.

The pleural space is a potential cavity between the lung and the chest wall-more specifically, between the visceral pleura and the parietal pleura. In the average healthy patient, this space is less than 1 mm thick. There are a number of pathologic processes that can alter the transport of cells and fluid within this space and thus give rise to clinically significant sequelae.

One such process is fibrothorax, which is defined as the presence of abnormal fibrous tissue within the pleural space, resulting in entrapment of the underlying pulmonary parenchyma (a state variously referred to as trapped lung, restrictive pleurisy, or encased lung).

Decortication is the surgical procedure by which this restrictive fibrous layer is peeled away from the lung; the literal meaning of the term is the stripping away of a rind. The technical goals of the operation are to re-expand the lung and resolve the pathologic process affecting the pleural space so that pulmonary function and chest wall mechanics will improve and the patient's symptoms will be relieved.

This aggressive cancer is often difficult to treat because by the time symptoms surface, the disease is already in advanced stages and there are few treatment options. Treatment options for patients with mesothelioma are usually determined by the stage of the cancer and the patient’s overall health.Many mesothelioma patients also opt to try different therapies such as massage therapy, acupuncture and mediation. Some patients also choose to control their disease through a vitamin supplement regimen and eating a raw, whole-food diet. There have been a number of asbestos cancer and other types of cancer survivors that credit their recovery to a strict nutrition and supplement plan.

Because mesothelioma is a rare disease, many new treatment options remain experimental, but patients may take advantage of clinical trials to gain access to these treatments. The preliminary results are encouraging and provide hope that these treatments may soon provide more options to mesothelioma patients.
