  Mesothelioma Overview

What is Mesothelioma?

Mesothelioma is a cancer that affects the lining around the lungs, heart, and abdominal cavities - called the mesothelium - which is primarily caused by chronic exposure to asbestos or asbestos related products. As asbestos fibers enter the body, either by breathing or swallowing, they cause normally healthy cells to mutate into cancer. This exposure can come directly, such as working in an asbestos processing center, or indirectly by inhalation of residual asbestos particles remaining on clothing or building materials. Studies show that exposure as short as one year can cause a variety of asbestos-related illnesses, including mesothelioma.

Three Types of Mesothelioma:

There are three main types of mesothelioma: Pleural, Peritoneal, and Pericardial.  Each affects a different area of the body, and can cause different symptoms.

Pleural mesothelioma:
Affects the lining around the lungs.  Microscopic and jagged asbestos fibers shred these delicate cells, and over time causes scarring and mutations that will eventually lead to cellular plaques.  These plaques prevent proper lung function and can lead to cancer.

Peritoneal mesothelioma:
This equally dangerous cancer affects the lining in the gut that surrounds the stomach and the intestines.  Asbestos particles can travel through the body and pierce these cells and cause tumors to develop.

Pericardial mesothelioma:
This rarest form of cancer affects the sack that surrounds the heart.  The pericardial sack provides the lubrication for the heart to beat properly, and when cancerous tumors and plaques develop it can cause a number of serious health problems.

Symptoms of Mesothelioma Types:

  • Symptoms of pleural mesothelioma:
    • Chest pain
    • Fluid in the lungs
    • Shortness of breath
    • Sustained cough
    • Hoarseness
    • Wheezing
  • Symptoms of peritoneal mesothelioma
    • Abdominal pain
    • Fluid in the gastrointestinal tract or abdomen
    • Lumps in the abdomen
    • Bowel movement difficulties
    • Weight loss
    • Nausea
  • Symptoms of pericardial mesothelioma:
    • Persistent cough
    • Chest pain
    • Heart palpitations
    • Shortness of breath

Mesothelioma and Cell Mutations.

Mesothelioma causes the cells of the mesothelium to mutate and multiply infinitely. This mutation causes tumors that can prevent proper lung and heart function. Because the cells of the mesothelium are responsible for providing fluid lubrication for the body’s internal organs, mesothelioma is particularly insidious because it can affect multiple organs simultaneously, usually without major symptoms or pain. Mesothelioma can also invade parts of the immune system, including bone marrow, lymph nodes, and spleen, where it continues to mutate and destroy healthy cells.

Development Time of Mesothelioma:

The cancerous cells also lie dormant for many years, and it is not uncommon for the first effects of mesothelioma to appear 20 to 30 years after initial exposure. Unfortunately, there is no cure for mesothelioma, and treatment ranges from preventive surgery to chemotherapy and radiation treatments. By the time symptoms manifest, it is quite often too late. Because mesothelioma lays dormant for so long, post diagnosis survival ranges from 1-5 years depending on the stage of the cancer and the age and condition of the victim.

Other Studies of Mesothelioma and Numbers of Asbestos Related Deaths:

Studies show that there are 10,000 asbestos-related deaths in the United States every year. These 10,000 people are not just a statistic; they are grandfathers and grandmothers, mothers and fathers, friends and neighbors. Very often asbestos companies knew the risks involved with their products, but chose to ignore the danger for the sake of profits. If you or a loved one has contracted Mesothelioma because of negligent use of asbestos, then you have a duty and obligation to seek restitution for your loss. Knowledgeable attorneys in your state are ready to take your case. Contact one today.

Mesothelioma in Military War Veterans – Navy personnel

Military war veterans – Navy personnel in particular - are at risk of developing mesothelioma because they were exposed to significant levels of asbestos in shipbuilding, insulation, and fire retardant materials on ship and at base.  Military necessity outweighed health concerns, and thousands of innocent people and their families are now paying the price for this oversight.  Even though veterans of the military cannot sue the government because of asbestos-related diseases, there are other ways to take action against those responsible. Furthermore, civilian military workers are also covered by the provisions of many special mesothelioma legal actions.

Mesothelioma in Mechanics and other Workers

Workers are the people at most risk of developing mesothelioma, because they worked directly or indirectly with the deadly materials.  There are dozens of at risk jobs, but some are more dangerous than others.  These include:

• Automotive mechanics
• Boiler makers
• Bricklayers
• Building Inspectors
• Carpenters
• Electricians
• Insulators
• Iron workers
• Laborers
• Longshoremen
• Maintenance workers
• Merchant marines
• Millwrights
• Painters
• Plasterers
• Plumbers
• Roofers
• Sheet metal workers
• Tile setters
• Welders

Family members of workers exposed to asbestos.

Perhaps the most tragic aspect of mesothelioma is the innocent family members of workers that had no direct exposure to the material but suffer from the disease nonetheless.  Workers who dealt with this deadly material often carried microscopic asbestos fibers home with them in their clothes and hair, which caused secondary exposure to their families and friends.  Over time, these innocent victims can develop mesothelioma, asbestosis, and other fatal conditions.

Other people that get mesothelioma.

There are other people that get mesothelioma besides other workers and their family members.  Because asbestos was used in thousands of different industries in thousands of different locations, people with no exposure to asbestos in the workplace are now suffering from this disease.  Asbestos insulation in churches, schools, recreation centers, and shopping centers can be responsible for a mesothelioma, asbestosis, or lung cancers.

Victims of Mesothelioma.

If you are an unfortunate victim of asbestos-related mesothelioma, regardless of how you developed it, you may be entitled to take legal action against those responsible for your condition.  Asbestos litigation is one of the most potent legal tools for victims of mesothelioma to reclaim the life stolen from them by the greed and deception of asbestos companies.  Contact a dedicated and experienced mesothelioma attorney today.

About the Disease

Simply put, mesothelioma is an aggressive form of cancer caused primarily by the inhalation of dangerous asbestos fibers. The disease attacks the mesothelium, a protective, two-layered membrane that covers the internal organs of the body including the lungs, heart and abdominal organs. Between these layers, the cells produce fluid, which allows easy movement of the heart and lungs within the chest cavity.  The layer that covers the lungs is called the pleura, and the layer that covers the heart is called the pericardium. The peritoneum lines the abdominal cavity.  Mesothelium also lines the male and female reproductive organs.   Mesothelioma can affect any of these cells, but is usually seen in the pleural or peritoneal mesothelium. The most commonly diagnosed form of mesothelioma is pleural.

Mesothelioma often takes anywhere from 20 to 50 years to develop, which is why older individuals are usually the victims. However, recent cases involving September 11th World Trade Center first responders and clean-up crews show that large concentrations of asbestos can cause the disease to develop much more rapidly. A few WTC workers have already died of the disease.

Effects of the Disease

The invasion of the mesothelium by cancer cells makes it very difficult for the patient to breathe, resulting in the need for oxygen, especially as the disease progresses. Those with the pleural form of mesothelioma may also suffer from pleural effusions. These effusions prevent the smooth movement of the lungs and other organs in the chest. Peritoneal mesothelioma also affects the stomach area and abdominal cavity, causing nausea, vomiting, or loss of appetite, which can result in dangerous weight loss. In addition to breathing difficulties and loss of appetite, mesothelioma victims also complain of excessive coughing, sleeping difficulties, persistent chest pain, fever, and pain in the lower back.

Mesothelioma, in general, is a very painful disease and because it is usually not diagnosed until it's in an advanced stage, the symptoms are quite serious. Late diagnosis also means that the cancer is more likely to have metastasized, or spread, making successful treatment even more difficult.

Who Gets Mesothelioma?

Statistics show that, because of their work history, the disease most often affects men between the ages of 50 and 70 who were employed in an asbestos-laden environment before asbestos warnings and bans were in place in the 1970s. Though women still have a much lower frequency of the disease, cases of second-hand exposure to asbestos has prompted more diagnoses among women, especially those whose male family members worked with asbestos. The occupations most associated with mesothelioma are shipyard workers, electricians, plumbers, construction industry workers, pipefitters, boilermakers, and anyone subject to heavy exposure to dangerous asbestos and airborne asbestos fibers.

An abundance of cases have also demonstrated that mesothelioma can develop among people who lived in communities where asbestos factories or mines were located. In some instances, entire towns have been adversely affected by the presence of asbestos fibers in the air. For example, in Libby, Montana - site of a former vermiculite asbestos mine - hundreds have already died of mesothelioma.

Though still significantly rarer than other cancers, an estimated 2,000 to 3,000 new cases of mesothelioma are diagnosed each year in the United States. Other countries, notably the United Kingdom and Australia, report a much higher incidence of the disease. Nevertheless, the United States - like many other countries - has seen an increase in asbestos-caused cancer as men who worked in U.S. shipyards in the 1940s and 1950s, at the height of production, are now being diagnosed with mesothelioma.

Dealing with Mesothelioma

Because mesothelioma is most often diagnosed in its late stages, such a diagnosis is often devastating to the individual and his/her family. Though research into the disease has been ongoing, there is currently no cure for mesothelioma. Some patients may be candidates for surgery to remove tumors or even an entire lung, but most are better treated with radiation or chemotherapy. More often than not, these treatments are palliative, serving to lessen the severity of the symptoms of the disease rather than offering a cure.

Medical professionals and research scientists, however, are constantly exploring new ways to combat the disease. For example, doctors know that some combinations of chemotherapy drugs work better than others and tests developed to ascertain earlier diagnosis of the disease or to monitor those most at risk have arrived on the scene.

Who's to Blame?

The reason someone develops mesothelioma is usually linked to the lack of proper protection offered to those who worked with asbestos. Though the dangerous properties of asbestos and asbestos products have been evident for decades, many employers neglected to protect their workers from inhaling asbestos while on the job. It wasn't until public awareness of the dangers of the material were revealed in the 1970s that many employers began offering protective clothing such as respirators, gloves, aprons, and other such items, to those working with asbestos on a daily basis.

Because of this negligence, many companies who manufacture asbestos or products that contain asbestos have been subject to literally thousands of lawsuits filed by those who've been harmed by the material. Many of those lawsuits have come from individuals suffering from mesothelioma.
