Mesothelioma and Non Asbestos Exposure

Mesothelioma typically develops in the lining of the lungs (pleura) and abdomen (peritoneum). This rare cancer also can form in the heart's lining (pericardium) or in the testes.

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

Exposure to Asbestos

Asbestos is a naturally occurring mineral that was previously used in industrial and construction products all over the world. People who worked in asbestos industries handled the substance every day, putting them at risk of exposure. Asbestos fibers can get trapped in the lungs, which can lead to progressive lung disease. This is referred to as asbestosis. As time passes, the asbestos fibers that have been trapped in the lungs may cause mesothelioma. Asbestos can also be inhaled or ingested and the risk of mesothelioma and other asbestos-related diseases increases depending on the duration and amount of exposure.

The majority of mesothelioma cases are caused by occupational exposure. Asbestos was used in many trades, such as construction, insulation, electrical work, automobile maintenance and pipefitting. These occupations are generally heavily populated by males and as a consequence 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 and non-occupational asbestos exposure becoming more common.

Non-occupational mesothelioma can occur when asbestos is released from the work environment or found in the home or school environment. It can also be caused by exposure to secondhand asbestos, such as when a family member is exposed to the clothing of an exposed asbestos worker. People who are exposed to this kind of exposure might experience symptoms such as shortness of breath or chest pain that is often mistaken for lung or heart conditions.

Some studies have linked non-occupational exposure to mesothelioma, however the results aren't consistent. A majority of these studies were conducted on a small sample size, and the between-study heterogeneity has been high. It is necessary to conduct further studies to confirm the link between non-occupational asbestos exposure and mesothelioma.

People who have been exposed to non-occupational asbestos should discuss their asbestos law history with their physician. If they are concerned, they should ask for a mesothelioma examination and referral to an expert. Mesothelioma specialists can offer patients the best treatment and care options to improve their chances of survival. They will analyze medical records and conduct imaging tests to determine if mesothelioma is present. They will also offer advice on how to file a mesothelioma suit to receive compensation from an asbestos trust fund.

Secondhand Exposure

While asbestos exposure is the primary cause of mesothelioma not the only way to develop this disease. In fact, there is only a tiny amount of evidence that suggests that people may develop mesothelioma, even if they have never 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 very small, and they can stick to hair, clothing, skin and other surfaces. In the end, workers can bring the dangerous fibers home in their work clothes, and then transfer them to family members. These stray asbestos lawyer fibers can be inhaled or swallowed, which can cause mesothelioma.

This type of mesothelioma occurs more often in women and is usually found in the lungs. It can also affect the chest wall or abdomen. The most commonly reported 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.

Pleural mesothelioma is a name used to describe mesothelioma that is found in the lungs. Mesothelioma that affects the stomach or chest wall is called peritoneal mesothelioma. This kind of mesothelioma could cause a number of symptoms like abdominal pain, difficulty breathing and constipation.

A number of studies have shown that individuals with no history of occupational exposure to asbestos could develop mesothelioma due to exposure to asbestos through secondhand fibers. These individuals typically resided with someone who had been exposed to asbestos. They could have handled the garments of the worker or had other contact with asbestos.

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

Environmental Exposure

A variety of materials have been linked to mesothelioma. However, the disease is most often associated with exposure to asbestos. Asbestos is a naturally occurring mineral that was utilized for a number of years in manufacturing. The mineral is heat-resistant and strong which makes it suitable for insulation, brakes, flooring, shingles, and many other products. When asbestos is broken down it releases dust that can be inhaled or swallowed. The asbestos fibers can stay in the stomach or lungs for years, and trigger mesothelioma-related symptoms.

The most frequent symptoms of mesothelioma are chest pain as well as abdominal discomfort, and difficulty breathing. Asbestos victims may suffer from these symptoms for 20 to 60 years or more after their first exposure. It is essential to consult a doctor when you experience these symptoms. It is also crucial to inform your doctor of your history with asbestos. This will prevent the wrong diagnosis and ensure you receive the right treatment.

Mesothelioma related to exposure to asbestos is most frequent in those who have worked directly with asbestos lawyer, but it can also be a problem for loved people who were exposed. This is called secondary exposure. Family members can inhale or swallow asbestos fibers on a worker's clothes, 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 should always take care to clean their clothes properly after working with asbestos.

There is a significant body of literature that shows a relationship between nonasbestos exposure and mesothelioma. However, there is no conclusive evidence yet about the role of other agents. There is evidence to suggest that the zeolites, namely erionite and chlorosotile are able to cause mesothelioma. Erionite is found in the soil and in the rocks of certain regions of Turkey where pleural mesothelioma rates are high.

Research into the relationship between mesothelioma and nonasbestos exposure is continuing. Funnel plots have revealed the possibility of bias in publication, and between-study heterogeneity is very high. However, it is still evident that occupational exposure to asbestos is the most significant risk factor for mesothelioma.

Genetics

The mesothelioma-related rare disease occurs when malignant cells in the mesothelium expand uncontrollably and invade surrounding tissues. It can be spread throughout the body traveling through the bloodstream or lymphatic system and affecting other organs. Although asbestos is the primary mesothelioma trigger, it is not the sole risk factor. The condition could be caused by other genetic or environmental factors.

In some cases, mesothelioma has occurred in people who were not exposed to asbestos. They are known as non-occupational mesothelioma sufferers. They usually had an indirect exposure due to the handling of contaminated clothing or household items by an asbestos-exposed person in their household. For instance, it is possible for people to be diagnosed with pleural mesothelioma due to the inhalation of asbestos fibers from clothing belonging to a loved ones. Research has shown that these types of mesothelioma cases are more likely to have longer periods of latency and are more likely to be diagnosed in wives rather than husbands.

Scientists are currently studying the possibility that mesothelioma's genetic susceptibility could play a part in the development of the disease. Recent studies have revealed that mutations in a gene called BAP1 can increase the risk of mesothelioma among those who have been exposed to asbestos (Full File). This is a significant finding because it could be the basis for improved screening procedures for those who are at risk of developing mesothelioma.

Researchers have discovered that a number of genes are involved in mesothelioma. Some of these genes are involved in reducing the growth of tumors and are frequently mutated or altered in mesothelioma sufferers. These genes include large tumor suppressor 2 (LATS2), and NF2.

People who have mesothelioma in their family are at greater risk for the mesothelioma. Certain genes, like BAP1, for instance, BAP1, are inherited from parents. Asbestos was extensively used in the military for a number of years, and veterans have the highest mesothelioma rate in comparison to other occupational groups. The people who served in the Navy and on ships specifically were at risk the most due to the high exposure to asbestos in fireproofing, insulation materials and shipbuilding.
