Mesothelioma and Non Asbestos Exposure

Mesothelioma most commonly develops in the lung lining (pleura) and abdomen (peritoneum). This rare cancer can also form in the linings of the heart or the testes (pericardium).

Asbestos exposure is the primary risk factor for mesothelioma. However, some patients diagnosed with mesothelioma don't have a history of asbestos exposure.

Exposure to Asbestos

Asbestos is a naturally occurring mineral that was once used in industrial and construction products worldwide. People who worked in asbestos industries handled the material every day and were at risk of exposure. Asbestos particles can be trapped in the lungs, where they cause progressive lung disease. This is referred to as asbestosis. As time passes, the asbestos fibers that have been trapped in the lungs can also cause mesothelioma. Asbestos can also be breathed in or ingested, and the risk of developing mesothelioma and other asbestos-related diseases rises with the amount and length of exposure.

Most cases of mesothelioma result from occupational exposure. Asbestos was employed in various trades, including construction insulation and electrical work, as well as automobile maintenance and pipefitting. These trades are typically predominantly male-dominated and, as a result mesothelioma-related cases of males account for 75-80% of all reported cases. However, the phasing out of asbestos in the United States and other first-world countries has reduced exposure to asbestos on the job. This has resulted in a shift in the number of cases, with non-occupational asbestos exposure increasing in frequency.

Non-occupational mesothelioma can develop when asbestos is released from a work environment or in the school or home environment. It can also be caused by exposure to secondhand asbestos for example, when a family member is exposed to the clothing of an exposed asbestos worker. Those who experience this type of exposure may experience symptoms such as shortness of breath or chest pain that is often mistaken as lung or heart problems.

Some studies have linked mesothelioma with non-occupational exposure, but the results differ. These studies were conducted with a very few participants, and the variability between studies was quite high. It is necessary to conduct further research in order to confirm the link between non-occupational asbestos exposure and mesothelioma.

People who have been exposed to non-occupational asbestos should discuss their asbestos medical history with their physician. If they are concerned, they should seek for a mesothelioma examination and referral to an expert. Mesothelioma specialists are able to provide patients with the most effective treatment and care options to improve their chances of survival. They will review medical records and perform imaging tests to identify mesothelioma. They will also offer advice on how to file a mesothelioma lawsuit to receive compensation from an asbestos trust fund.

Secondhand Exposure

While asbestos exposure is the main cause of mesothelioma, it's not the only way to develop this disease. In fact, there is a small amount of evidence that suggests that people may develop mesothelioma despite not having directly handled asbestos or employed in an industry that has asbestos-related activities. This is referred to as secondary or non-occupational asbestos exposure.

Asbestos fibers are extremely small and they can stick to hair, clothing skin, and other surfaces. As a result, workers could bring the hazardous fibers home in their work clothes and then transfer them to family members. These stray asbestos fibers can be inhaled or swallowed, which can cause mesothelioma.

The mesothelioma type is more common in women, and it usually occurs in the lung. However, it can occur in the abdomen or chest wall. The most common sign is a shortness of breath (dyspnea), and it is often accompanied by other symptoms like fluid in the lungs or swelling in the scrotum.

The mesothelioma which occurs in the lungs is called pleural mesothelioma. Mesothelioma that affects the stomach or chest wall is referred to as peritoneal mesothelioma. People suffering from this kind of mesothelioma may experience a variety of symptoms such as abdominal pain, breathing difficulties and constipation.

Several studies have reported that individuals with no background of occupational exposure to asbestos may develop mesothelioma due to exposure to asbestos through secondhand fibers. The people who were affected typically lived with someone who had been exposed to asbestos. They might have handled the worker's clothing or had other contact with asbestos.

Veterans are at a high risk of mesothelioma because asbestos law was widely used in military bases, vehicles and ships. The Navy is especially at risk because asbestos was used to protect the hull of the ship as well as to protect gun turrets. In addition, sailors often brought home asbestos from their jobs on ships that were contaminated with asbestos.

Environmental Exposure

A variety of materials have been associated with mesothelioma. However, the condition is most often associated with exposure to asbestos. Asbestos is a mineral that occurs naturally that was used for a variety of years in the production of. The mineral is heat-resistant and tough, which makes it ideal for use in insulation, brakes, shingles, flooring and other products. When asbestos is broken down it produces dust that can be breathed in or swallowed. The asbestos fibers can stay in the lungs or stomach for years, and trigger mesothelioma symptoms.

The most frequent mesothelioma symptoms are chest pain, abdominal discomfort and trouble breathing. Asbestos victims might be suffering from these symptoms for up to 60 years or more following their first exposure. It is essential to consult a doctor when you experience these symptoms. It is also important to inform your doctor of your history with asbestos. This will prevent a faulty diagnosis and ensure that you receive the proper treatment.

Mesothelioma that is caused by exposure to asbestos is more frequent in those who have worked directly with asbestos, but it can also affect the loved people who were exposed. This is referred to as secondary exposure. Family members could inhale or swallow asbestos law fibers on the clothing of a worker, tools or shoes. They may be exposed to asbestos to asbestos by someone who brings home these particles on their clothing or hair. This is why mesothelioma patients and their families must be sure to wash their clothing properly after working around asbestos.

There is a significant amount of research that suggests a relationship between nonasbestos exposure and mesothelioma. However, there are no definitive conclusions yet about the role of other agents. There is evidence to suggest that zeolites, namely erionite and chlorosotile, can cause mesothelioma. Erionite is found in the soil and rocks in certain parts of Turkey, where mesothelioma incidences are high in pleural mesot.

The research on the connection between mesothelioma and nonasbestos exposure continues. Funnel plots indicate the possibility of publication bias and there is a large level of heterogeneity between studies. However, it is still clear that occupational exposure to asbestos is the most significant risk factor for mesothelioma.

Genetics

Mesothelioma is an uncommon disease caused by malignant mesothelial cells which expand beyond control and invade surrounding tissues. It can be spread throughout the body by traversing the lymphatic system or bloodstream and affecting other organs. Although asbestos is the primary mesothelioma trigger, it isn't the only risk factor. The condition can be caused by other genetic or environmental factors.

In a few cases mesothelioma is seen in people who had no direct exposure to asbestos. They are known as non-occupational mesothelioma victims. They typically experienced indirect exposure from the handling of contaminated clothes or home items by an asbestos (Full Posting)-exposed person in their home. For instance, it is possible for one to be diagnosed with pleural mesothelioma as a result of the inhalation of asbestos fibers from clothing belonging to a loved ones. Research has shown that this form of mesothelioma tends to have an extended latency time and is more likely to affect women than men.

Scientists are investigating the possibility that mesothelioma-related genetic predispositions could play a role in its development. Recent studies have demonstrated that mutations in a gene called BAP1 increases the risk of mesothelioma among those who are exposed to asbestos. This finding is especially important because it could be the basis for improved screening procedures for those at risk of developing mesothelioma.

Researchers have discovered that a variety of genes are associated with mesothelioma. Some of these genes are involved in reducing tumor growth and are often altered or mutated in mesothelioma patients. These genes include large tumor suppressor 2 (LATS2) and NF2.

A family history of the disease increases the risk. This is because some genes, like the BAP1 gene, can be passed down from an individual parent. Asbestos was used heavily in the military for a number of years, and veterans have the highest mesothelioma rates compared to other occupational groups. Those who served in the Navy and on ships were at the highest risk due to extensive exposure to asbestos in fireproofing, insulation materials and shipbuilding.
