Causes of Mesothelioma Cancer

The leading cause of malignant mesothelioma cancer is prolonged and repeated asbestos exposure. Inhaled asbestos fibers cause tissue damage that can lead to cancer, most frequently around the lungs. Most people with mesothelioma were exposed to asbestos in the workplace.

What Is Most Likely to Cause Mesothelioma?

Asbestos exposure is the leading and most likely cause of mesothelioma.

Before the 1970s, many industries used asbestos and asbestos-containing materials (ACMs) because of their ability to insulate against heat and protect against fire.

After extensive research and investigations determined that asbestos is extremely harmful to people, most businesses and manufacturers stopped using it. However, this was decades after extensive exposure in millions of people.

Even though experts determined that asbestos was dangerous, several businesses continued to use it. It was a matter of profits over care for workers.

Unlike other forms of cancer, mesothelioma doesn’t have a long list of causes. One of its alternate names is asbestos cancer because the primary cause of mesothelioma is long-term exposure to asbestos.

Who Is at Risk for Mesothelioma?

Asbestos exposure is the leading cause of mesothelioma, but not everyone knows how much they were exposed to in the past or if they were exposed at all. These are some of the most critical risk factors for a mesothelioma diagnosis:

• Worked in an industry that used asbestos
• Served in the military
• Older age and male
• Lived with someone who worked with or around asbestos
• Family history of mesothelioma

Some of the jobs that most put people at risk for asbestos exposure included:

• Construction
• The military (especially the Navy)
• Automotive repair work, especially brakes and clutches
• Industrial plants and factories
• Asbestos products plants
• Vermiculite processing plants
• Ship repair and shipbuilding

People who worked with asbestos have the highest risk of mesothelioma. Also at risk are people who lived with them. Family members were often exposed at home through secondhand exposure.

Workers inadvertently brought asbestos fibers home on their clothing, causing repeated exposure. Some of these family members later developed mesothelioma.

Asbestos and Mesothelioma Studies

In 2009, the International Agency for Research on Cancer (IARC) confirmed the investigations and findings and released a statement that the primary cause of mesothelioma is asbestos exposure.

The statement indicated that people who worked around asbestos daily run the highest risk of getting mesothelioma. The most common work sites associated with using asbestos include:

• Factories and industrial sites
• Steel mills
• Asbestos and other mines
• Asbestos processing plants

People at home are also at risk, especially if they live near a naturally occurring asbestos deposit site or in an older home built during peak asbestos use.

Two other studies performed in 2010 by the Mesothelioma Applied Research Foundation and the Cancer Institute revealed again that the leading cause of mesothelioma is asbestos exposure.

Once the fibers enter, it’s almost impossible for the body to expel them. The fibers then begin to attack the mesothelium, which in turn causes lesions and tissue damage.

Over time, cells in the damaged tissue may become cancerous and form tumors. It can then take up to 50 years for the first symptoms of mesothelioma to surface.

How Does Asbestos Cause Mesothelioma?

People are exposed to asbestos by inhaling the delicate fibers that the mineral produces. These fibers then get lodged in the lungs. Someone can also unknowingly swallow asbestos, and the fibers make their way down to the abdominal area.

Asbestos fibers in the body can cause significant tissue damage, causing scarring and inflammation. In some people, this leads to mesothelioma. Although scientists and physicians are still trying to determine exactly why asbestos fibers cause cancer, researchers have several ideas:

• Changes in Genetics. Asbestos can disrupt mesothelial cells, which are naturally occurring cells in the body. This, in turn, hinders the functions of the cells, which can lead to cancer.
• Inflammation of Cells. When the body’s cells become irritated, inflammation and scarring occur. Consequently, it leads to cell damage and cancer.
• Free Radicals. Asbestos produces free radicals in the body. Once this happens, DNA can become damaged, which leads to cancer.
• Oncoproteins Growth. When asbestos is in the body, cells begin producing oncoproteins. Oncoproteins hinder normal cell production, which can consequently lead to cancer.

Inhaled asbestos is most likely to cause pleural mesothelioma, which develops in the tissue around the lungs. Ingested fibers may cause a less common form in the abdomen called peritoneal mesothelioma. Even rarer is pericardial mesothelioma, which develops around the heart.

Is Mesothelioma Caused by Anything Other Than Asbestos?

Asbestos exposure is the only widely proven cause of mesothelioma. However, some people are diagnosed with no known asbestos exposure.

Some of these additional diagnoses may involve people who were exposed to asbestos in the past but didn’t know about it. Others are certain to have had no asbestos exposure, which means there are other causes or contributing factors for mesothelioma.

Secondary Cause of Mesothelioma: Drug Interactions

Although rare, some mesothelioma patients have never been exposed to asbestos. Researchers found links between a drug called Thorotrast and mesothelioma.

Patients administered the drug are at an elevated risk of developing lung carcinoma and mesothelioma.

Thorotrast is a mixture of particles used primarily in the 1930s and 1940s when performing X-ray imaging. It helped the physician produce high-quality images, but the particles remain in the human body.

SV40

Simian Virus 40 (SV40) has also been linked to mesothelioma. SV40 is a virus found in a few species of monkeys and later found in Polio vaccinations.

More than 90 million Americans received a Polio vaccination between 1955 through 1963. It was during this period that the Polio vaccine was contaminated with SV40.

Although humans typically aren’t susceptible to mesothelioma after getting the vaccine, studies have shown that at least 40 patients with mesothelioma also have traces of SV40. More research is needed to understand how this happens.

Erionite

Another possible cause of mesothelioma is exposure to erionite. Though much less common than asbestos exposure, erionite is similar to asbestos in that both are naturally occurring minerals that are harmful when ingested or inhaled.

Furthermore, erionite-caused cancer mimics the same process of development as asbestos-related cancers, taking up to 50 years for the first symptoms to appear.

However, the biggest difference is that erionite is inhaled and ingested primarily through the environment and not in the workplace.

Studies have also shown that erionite poses a higher risk of victims developing mesothelioma and other types of lung cancers when compared to asbestos. Mesothelioma also develops more quickly and with less exposure to erionite than asbestos.

Erionite can be found in volcanic ashes that weather and water disrupted. In rare instances, erionite has been found in water purification systems and softeners. Usually, however, erionite is found in natural deposit sites.

There are known erionite deposits throughout the world, including:

• Russia
• Japan
• Germany
• Turkey
• Kenya
• Italy

In the United States, erionite deposits can be found in:

• North Dakota
• Wyoming
• Arizona
• Oregon
• Nevada
• California
• Utah

Turkey yields the highest amount of erionite. In fact, in the village of Tuzkoy, there is an extremely high amount of malignant mesothelioma victims because of the naturally occurring and high amounts of erionite deposits surrounding the area.

In the United States, scientists are still studying the adverse effects of erionite, particularly in North Dakota. The risks appear low compared to asbestos, but more study is needed.

Mesothelioma and Genetic Factors

Experts have suggested that certain people may be genetically predisposed to developing mesothelioma. Genes are not likely to cause mesothelioma, but they might increase the risk of developing mesothelioma after asbestos exposure.

Research funded by the National Institutes of Health (NHI) found a specific mutation gene called the BAP1 that puts the carriers of the gene at significant risk for developing both mesothelioma and melanoma of the eyes. These people are also at a much higher risk of developing an asbestos-related disease if they are exposed to the mineral.

People with BAP1 are also at risk for developing different kinds of cancers, such as breast, ovarian, pancreatic, and renal.

Know the Signs of Mesothelioma for an Early Diagnosis

The symptoms are almost always the same regardless of how someone contracts mesothelioma. Remember that some people may exhibit more symptoms than others, and it typically takes decades for even the most common symptoms of mesothelioma to surface.

Typical mesothelioma symptoms include:

• Chest pain that can fluctuate from minor to severe
• Fluid buildup in the lungs
• Difficulty swallowing and pain when attempting to swallow
• An overwhelming sense of fatigue and lethargy
• Nausea and vomiting
• Unexplained weight loss
• Dyspnea (shortness of breath)
• Dry coughing, wheezing and hacking
• Pleural effusions

Less Common but more serious symptoms include:

• Lung Collapsing
• Coughing up blood
• Nerve damage in the arms
• Blood clots on the hands and arms
• Horner’s Syndrome (rare condition that affects the nerves in the eyes and face)

How to Prevent Mesothelioma

The best way to prevent mesothelioma is to protect yourself from asbestos exposure. You might not be able to reverse past exposure, but if you worked around asbestos or have mesothelioma symptoms, act quickly. The earlier you get a diagnosis, the more treatment options you have.

If you currently work in an industry that might have asbestos, you should be provided with safety training, information, and protective gear. If not, you can file a complaint with the Occupational Safety and Health Administration (OSHA).

OSHA ensures companies limit asbestos exposure and provide workers with information, training, and gear.

If you live in an older home, find out if you have asbestos by contacting a licensed inspector. It is especially important to avoid doing any renovation or repair work until you know the location of any asbestos.

If you were diagnosed with mesothelioma, contact a lawyer to seek compensation from the companies responsible for your asbestos exposure.
