New Developments in Mesothelioma explore and Treatments

Cancer investigate and improvement is an ongoing process. In the field of mesothelioma treatment, researchers are focusing on enhancing original treatments as well as developing new techniques to ease the pain of patients. New chemotherapy agents and combination’s are now giving new hope to mesothelioma patients and are addition the survival rate amongst them. Any new advances have improved prognosis and rehabilitation of this incurable disease. Hoping for a cure in the near hereafter is therefore not something surreal.

Peritoneal Mesothelioma Survival Rates

Peritoneal Mesothelioma is a cancer of the abdomen lining caused due to prolonged exposure to asbestos. Thousands of lawsuits are handled every year dealing with the issue of peritoneal mesothelioma and its effects. Symptoms of mesothelioma may not appear until 30 to 50 years after exposure to asbestos. Shortness of breath and pain in the chest due to an accumulation of fluid in the pleural space are often symptoms of pleural mesothelioma Other symptoms of peritoneal mesothelioma comprise loss of appetite, nausea, and abdominal swelling. Fluid ordinarily accumulates in the abdominal cavity causing the swelling and pain. The symptoms can come to be quite serous over time, as the swelling will exert great force on surrounding organs and lead to great pain.

Asbestos Infection Symptoms

The types of asbestos infection symptoms a someone experiences regularly depends on the developed asbestos-related diseases was. There are dissimilar types of conditions associated to asbestos, asbestosis, the two are most often associated with asbestos and malignant mesothelioma. Any way persisting obstructive pulmonary disease (Copd) has reached the epidemic proportion in the United States and it is a health that the asbestos exposure has helped thousands of cases.

Quebec Government Extends Deadline for Asbestos Mine Relaunch

The Quebec government announced Monday that it will allow more time for private investors attempting to relaunch the Jeffery asbestos mine to complete their financing talks. The group now has until Oct. 1 to raise the $25 million the Quebec government is demanding before it can guarantee $58 million of loans. The initial deadline ran out Monday, August 15. It was the second extension granted to the consortium, but this time, according to government spokesperson Gabrielle St-Amand, the deadline must be “strictly” respected.

What Causes Mesothelioma?

Mesothelioma is a cancer that occurs in the mesothelium, a thin membrane encompassing the body’s internal organs and cavities. Mesothelioma is caused by asbestos exposure. Asbestos fibers that are inhaled through the mouth and nose may eventually become embedded in the lining of the lungs, causing harmful inflammation of the pleura and resulting in mesothelioma or asbestosis (scar tissue formation in the lungs). It has also been found that swallowing asbestos fibers could contribute to a form of the malignancy originating in the abdomen known as peritoneal mesothelioma.

Mesothelioma generally results from occupational asbestos exposure but there are instances of environmental exposure that can also cause the disease. Oftentimes a family member can be affected indirectly by second hand exposure from an asbestos worker’s soiled work clothes.

Asbestos was an effective insulation material. It was used liberally in commercial and industrial products in the United States until being regulated in a joint effort between the Consumer Product Safety Commission and the Environmental Protection Agency in 1989. Occupational exposure was common among workers who encountered these products in many industries including shipbuilding, power plants, and other industrial settings.

Asbestos insulation workers appear to have the highest rate of asbestos related disease. One study reports that almost six percent of asbestos workers fall victim to mesothelioma or experience respiratory symptoms. Asbestos insulation workers are over 300 times more likely to be diagnosed with mesothelioma than those with no exposure history.

How does exposure to asbestos cause mesothelioma?

Asbestos fibers are microscopic, though they are also quite durable. For this reason, asbestos was used in a number of different industrial compounds to enhance strength and resistance to temperature extremes- two properties at which the mineral is highly adept. Asbestos exposure most often occurred among individuals who worked extensively with asbestos or asbestos-containing materials. Friable asbestos (meaning loose or airborne fibers) is easily inhaled- often without the exposed person realizing.

When inhaled, asbestos lodges easily in the outer lung tissue and within the mesothelium. The mesothelium is a thin membrane of cells which produces a lubricating fluid on the surface of the organs. This lubricant allows the lung and other internal structures to expand, contract, and move freely without friction in the body cavity. There is a great deal of latency associated with mesothelioma between exposure to asbestos and the onset of symptoms. Over time (often 40 or 50 years) asbestos irritates this tissue, causing inflammation and malignant scar tissue plaques on the surface of the mesothelium. These plaques are the foundation of the mesothelioma tumor. 

Pleural mesothelioma is the most common variety of the disease and forms on the pleural membrane, which surrounds the lung and chest cavity. Peritoneal mesothelioma is less common and forms on the surface of the peritoneum, a thin membrane surrounding the abdominal cavity. Pericardial mesothelioma is the least common variety of the disease and forms in the cardiac cavity that envelops the heart, a mesothelial membrane known as the pericardium. 

Inhaled asbestos fibers are known to be the cause of pleural mesothelioma, whereas ingested asbestos fibers are the cause of peritoneal mesothelioma. While the exact causal nature between asbestos and pericardial mesothelioma is not known, physicians and cancer researchers surmise asbestos fibers in the blood stream lodge in the outer layers of the heart’s ventricles and lodge in the pericardium. Once asbestos fibers reach the surface of the peritoneum or pericardium, the inflammation process is essentially the same as it is on the surface of the pleura. 

Primary workplace exposure to the mineral was common in naval shipyards, power plants, railroad infrastructure, and other industrial jobsites. However, asbestos-related mesotheliomas have also been diagnosed in spouses or children of those exposed to asbestos. Workers often brought home dangerous asbestos fibers on their clothing, hair, or person. Those who came into contact with these fibers on the person or their clothing have developed mesothelioma as a result.

Smoking and Mesothelioma

It has long been known that smoking is hazardous to one's health, causing a marked increase in instances of mesothelioma lung cancer among those who smoke regularly. However, smokers who are or have been exposed to asbestos carry a much higher risk of developing an even more serious disease - malignant mesothelioma, a difficult-to-treat cancer that affects the lining of the lungs (pleural mesothelioma), heart (pericardial mesothelioma), or abdomen (peritoneal mesothelioma).

Exposure to asbestos has been identified as the major cause of mesothelioma cancer. The disease occurs when an individual inhales sharp asbestos fibers, which then become lodged in the lungs. Smoking, according to the Centers for Disease Control, weakens the lungs and decreases a body's ability to remove asbestos fibers. Further, cigarette smoke irritates the air passages and causes them to produce more mucus which, in turn, blocks the passage of air and the dispelling of fibers.

According to a variety of studies that have been performed throughout the last two decades, while cigarette smoking alone does not lead to mesothelioma, cigarette smokers who are exposed to asbestos are about 50 to 84 times more likely to develop asbestos lung cancer and, most experts agree, these smokers are at least twice as likely to develop mesothelioma.

Furthermore, mesothelioma risk factors are higher for those who have already developed a less serious asbestos-related disease, namely asbestosis. Also, the more packs a day that an asbestosis sufferer smokes, the higher the chance for developing this aggressive cancer. Simply stated, those who have asbestosis should stop smoking. A cessation of smoking, according to studies by the National Cancer Institute, results in a 50 percent decrease in the risk for a mesothelioma diagnosis within about five years of quitting, a figure that is encouraging for smokers with early asbestos disease.

Smokers who have been exposed to asbestos and have not quit should submit to regular medical check-ups to determine the health of their lungs. Tests to monitor the formation of asbestos cancer, such as mesothelioma, might include a chest x-ray or a lung function test. In addition, a simple blood test known as the Mesomark® assay, used to detect the presence of mesothelioma, may be in order for smokers who suffered asbestos exposure.

Exposure To Asbestos

Exposure to asbestos particles is one of the principal causes of mesothelioma cancer, also known as asbestos cancer. As a naturally occurring mineral with useful commercial applications, asbestos is found in plumbing, insulation and other building materials and products.

Through the liberal commercial use of this material, most people in the United States and other industrial nations have been or will be exposed to loose, airborne particles in their work or home environments, this exposure can create significant health hazards.

Commercial Applications

Over 700,000 schools and buildings in the United States today contain asbestos insulation as reported by the US Environmental Protection Agency. Asbestos exposure doesn't stop there, however. Asbestos is often found in ship yards, manufacturing facilities, railway facilities and construction sites. Blue collar workers are at the highest risk for developing mesothelioma due to occupational exposure. They typically work in aluminum plants, oil refineries, chemical plants, mines, factories, shipyards, construction sites and railroads. Employees at insulation and gas mask manufacturing facilities are also at risk. The occupations most widely affected are miners, factory workers, railroad workers, ship builders and construction workers - especially those who install asbestos-containing insulation. Sometimes family members related to the workers receive second hand exposure to asbestos from the dust and fibers that were brought home on the workers clothes and also become at risk for contracting mesothelioma.

There are six different types of asbestos: chrysotile, amosite, crocidolite, tremolite, anthophyllite and actinolite. These six mineral types are divided into two classifications, serpentine and amphibole. Chrysotile is the only mineral in the serpentine class. As known carcinogens both classes of asbestos can cause mesothelioma.

In the United States, chrysotile was the most commonly used asbestos mineral, and is known for its curly fibers that can be easily woven into fabrics. Applications of chrysotile include drywall compound, plaster, vinyl floor tiles, roofing materials, acoustic ceilings, fireproofing, caulk, brake pads and shoes, stage curtains, fire blankets and dental cast linings.

Amosite and crocidolite are the other more common asbestos minerals used, though their application is not as extensive as chrysotile. Products manufactured out of these asbestos minerals include insulation board, ceiling tiles and casing for water services.

In the past ten years, trace amounts of asbestos have been found in talc, a leading ingredient in crayons.

Exposure and Health Risks

The extensive use of asbestos across many different industries exposes not only those individuals working in the manufacturing of raw asbestos or working with asbestos-related products, but also individuals who may have asbestos in their homes, churches or schools. Further, asbestos particles may cling to the clothing or hair of an individual working with asbestos and potentially contaminate others.

Though chrysotile is the most common form of asbestos used in products and is a known carcinogen, amosite and crocidolite asbestos are the most hazardous to health. All types of asbestos can linger in an individual’s lungs for many years after exposure, but amosite and crocidolite are the most persistent, lingering particles.

There is a higher risk for individuals working in asbestos-related environments, though many individuals with minimal exposure can also have damage that can lead to mesothelioma cancer or other diseases.

Although asbestos exposure may have hit its peak from the turn of the twentieth century through the 1970s, many individuals are still being subjected to asbestos particles. Arguably, the most recent and tragic mass exposure resulted from the attacks on 9/11, where tons of asbestos particles were released into the air, harming thousands of rescue workers and individuals living near Ground Zero. Diagnosed with asbestos cancer due to their prolonged, persistent exposure, many brave firefighters, police and rescue workers continue to suffer.

Further, many individuals continue to be exposed to asbestos in older homes. With the boom of Do-It-Yourself projects, many homeowners are tackling renovations without knowing the potential health risks. Attempting renovations in these environments may disturb asbestos causing it to become airborne and inhaled. Without knowledge of where asbestos may be located in these homes, there is a significant risk of accidental exposure, and any homeowner should have professional do a thorough inspection before any projects begin. Removal should always be handled by a professional contractor and should not be attempted by homeowners.

One of the groups hardest hit from asbestos-related diseases are America’s veterans. All branches of the United States military used equipment, gear and products laden with asbestos, unwittingly exposing young men and women between the 1940s and late 1970s. Most veterans repeatedly exposed to asbestos suffer from mesothelioma disease.

For over one hundred years, almost every product that we can come in contact with may have been produced with asbestos components. From decorative household items, to products manufactured to protect firefighters, to dental products, asbestos has been the silent, deadly part of recent American industry.

Asbestos Related Disease

Some research points to the fact that inhaled asbestos fibers cause a physical irritation resulting in mesothelioma rather than the cancer being caused by a reaction that is more chemical in nature. As fibers are inhaled through the mouth and nose they are cleared from the body by adhering to mucus in the nose, throat and airways and then get expelled by coughing or swallowing. The Amphibole fibers (long and thin) do not clear as easily and it is therefore thought that they can embed into the lining of the lungs, chest or stomach causing scarring and inflammation which increases the risk for mesothelioma cancer. Mesothelioma symptoms can be detected as early as ten years after exposure and can incubate as long as forty years.

Asbestosis (scar tissue in the lungs) or mesothelioma lung cancer can also be caused by the inhalation of asbestos fibers. In fact, people exposed to asbestos are seven times more likely to develop lung cancer over the general public. Workers who sustain high levels of asbestos exposure are more likely to die from asbestosis, lung cancer or mesothelioma than any other disease. It is also believed that the action of coughing up and swallowing asbestos could contribute to a form of mesothelioma originating in the abdomen called peritoneal mesothelioma. This disease has been found to exist in other organs of the body as well such as the larynx, pancreas and colon, but those instances are extremely limited compared to lung cancer incidents.

The chance of developing mesothelioma is in direct proportion to the duration and amount of asbestos exposure that an individual sustains. Those who are exposed to high levels of asbestos at a young age, for long periods of time have a greater risk of being diagnosed with mesothelioma than those who have short, low level exposure. Another important consideration is that the mesothelioma latency period is very long. Often, twenty to forty years can elapse from the time of exposure to diagnosis. Genetic factors can also play a role which explains why not everyone exposed to asbestos develops an asbestos related disease.

What Is a Mesothelioma Lawsuit?

A mesothelioma lawsuit is a way for a victim of asbestos-related cancer, or mesothelioma, to be awarded damages or compensation. By filing and winning a mesothelioma lawsuit, the person affected with cancer can receive reimbursement and compensation for their medical expenses, receive any income lost because of the disease, and receive compensation for pain and suffering due to the disease. Mesothelioma is caused solely from exposure to asbestos; however, it can take decades for the cancer to show up. Unless it is discovered early, the victim only has a short time to live, usually about one year after a late diagnosis.

Asbestos has been used in thousands of products for centuries. It is a natural product that is most commonly found in the brakes of cars, around the wiring of homes, and in other building materials, including rooftops and siding of older homes. The benefit of asbestos is that it reduces heat transfer and corrosion. The detriment of asbestos is that if it is inhaled or if someone is exposed to its fibers, it is deadly. The people at highest risk for asbestos exposure and who are most likely to file a mesothelioma lawsuit are those who work in home repair, construction, railroad, car, and factory industries; however, people who handle the clothing of those who work with asbestos are equally at risk.

There are several parties that can be held culpable for a mesothelioma lawsuit. Liability mainly rests with the employers and the product manufacturers. In other words, the company that employed the victim and the company that made or manufactured the asbestos-laden product can usually be sued.
There are several factors that must be considered before full liability will be passed on to a party for a mesothelioma lawsuit. Specifically, the court will consider whether the company was aware or should have been aware of the dangers of asbestos. For example, if the company knew or should have known that the product contained asbestos and knew that asbestos was dangerous, but opted not to tell its employees, it can be held liable. In addition, if the company knew of the dangers and failed to take the necessary precautions to protect its employees, it can be held liable.

As with most lawsuits, time is of the essence for a mesothelioma lawsuit. Every jurisdiction has its own laws that state how long a plaintiff has to sue a company before the statute of limitations runs out. For example, in some places, a person must sue a company within three years of discovering she has mesothelioma. If she attempts to sue the company after three years, she will be told it is too late.

Most mesothelioma lawsuits take a year to complete. In many cases, the plaintiff dies before the lawsuit is resolved. As a result, it is always best to consult a lawyer dedicated to asbestos litigation and mesothelioma as soon as the condition is discovered.
