Mesothelioma and Non Asbestos Exposure
Most commonly, mesothelioma develops on the lung linings and abdomen. This rare cancer also can form in the heart's lining (pericardium) or in the testes.
Asbestos exposure is the main risk factor for mesothelioma. However, some people diagnosed with mesothelioma do not have an asbestos-related history.
Exposure to Asbestos
Asbestos, a rock that is of natural origin was previously used for industrial and construction products throughout the world. The workers in asbestos industries handled the material on a daily basis which put them at risk of exposure. Asbestos particles can be trapped in the lungs, which can cause lung diseases. This is known as asbestosis. As time passes, the asbestos fibers that are trapped in the lungs could cause mesothelioma. Asbestos can also be breathed in or consumed and the risk of mesothelioma and other asbestos-related diseases increases with the length and quantity of exposure.
The majority of mesothelioma cases result from occupational exposure. Asbestos is a common ingredient in jobs, including electrical work and vehicle maintenance. These trades are typically dominated by men and as a consequence mesothelioma cases involving males make up 75-80% of all reported cases. However, the phasing out of asbestos in the United States and other first-world countries has decreased on-the-job exposure. This has caused a shift in cases, with non-occupational exposure becoming more prevalent.
Non-occupational Mesothelioma is caused when asbestos is released in the workplace or found at home or in schools. It can also be caused by exposure to secondhand asbestos, such as when a family member is exposed to the work clothes of an asbestos worker who has been exposed. Those who experience this type of exposure might experience symptoms like shortness of breath or chest pain, which is often mistaken for lung or heart problems.
Pueblo asbestos attorneys have linked mesothelioma to non-occupational exposures, but the results vary. A majority of these studies have been conducted on a small sample size, and between-study the degree of heterogeneity is high. It is necessary to conduct additional research in order to confirm the connection between asbestos exposure from non-occupational sources and mesothelioma.
People who have had non-occupational asbestos exposure should speak to their doctor regarding their asbestos-related history. If they are concerned, they should ask for a mesothelioma test and a referral to an expert. Mesothelioma specialists can provide patients with the best treatment and care options to improve their prognosis. They will analyze medical records and conduct imaging tests to identify mesothelioma. They will also give advice on how to file a mesothelioma lawsuit to obtain compensation from an asbestos trust fund.
Secondhand Exposure
While asbestos exposure is the leading cause of mesothelioma, it's not the only reason to develop this cancer. There is evidence that people who have never been exposed to asbestos or worked in industries with asbestos-related work can still develop mesothelioma. This is called secondary or non-occupational exposure to asbestos.
Asbestos fibers are extremely tiny, and they can stick to clothing, hair or skin as well as other surfaces. In the end, workers may bring the harmful fibers home on their work clothes and then transfer them to family members. These asbestos fibers could be swallowed or inhaled leading to mesothelioma.
This form of mesothelioma is more common in women, and it usually occurs in the lung. However, it can also occur in the abdomen or chest wall. Shortness of breath is the most typical indication. It may be accompanied by a variety of other symptoms, like lung fluid and swelling in the scrotum.
Pleural mesothelioma refers to the name that is used to describe mesothelioma, which occurs in the lungs. Mesothelioma that affects the chest wall, stomach, or is known as peritoneal mesothelioma. This kind of mesothelioma could cause a number of symptoms, including abdominal pain, difficulty breathing, and constipation.
According to a variety of studies, people who haven't been exposed to asbestos in the workplace may still develop mesothelioma due to exposure through secondhand sources. Typically, these individuals have been living with someone who was exposed to the hazardous material. They could have worn the clothing of an asbestos worker or had another contact.
Veterans are at a high risk of mesothelioma because asbestos was widely used in military bases as well as vehicles and ships. The Navy is at a higher risk since asbestos was used in the hulls and gun turrets of ships to guard them from fire. Asbestos was also often taken home by sailors after their work aboard ships that had been infected with asbestos.
Environmental Exposure
A variety of materials have been associated with mesothelioma. However, the condition is usually linked to exposure to asbestos. Asbestos is a naturally occurring mineral that was used for many years in the production of. The mineral is heat resistant and strong, making it ideal for insulation, brakes, shingles, flooring and other products. When asbestos is broken it produces dust that can be inhaled or swallowed. These fibers may remain in the lungs and stomach for many years, triggering mesothelioma-related symptoms.
The most frequent mesothelioma symptoms are chest pain, abdominal discomfort and trouble breathing. Asbestos exposure can cause these symptoms to last for up to 60 years. These symptoms could be mistaken for other illnesses, so it is important to see your doctor if you exhibit these symptoms. Telling your doctor about asbestos exposure is essential. This can prevent a wrong diagnosis and ensure that you receive the correct treatment.
The most frequent mesothelioma patients from asbestos exposure are those who have worked directly with it but it is possible for loved family members to be affected. This is referred to as secondary exposure. Family members could inhale or swallow asbestos fibers that are present in a worker's shoes, clothing or even tools. They may be exposed to asbestos by someone bringing home the particles on their clothing or hair. This is the reason mesothelioma sufferers and their families should always be sure to clean their clothes properly after working with asbestos.
There is a large amount of research that shows a link between nonasbestos and mesothelioma. However, there are still no definitive conclusions about the role of other agents. For example there is evidence that the zeolites erionite and chlorosotile may cause mesothelioma. Erionite is found in soil and rocks of certain parts in Turkey where the incidence of pleural mesothelioma is high.
The study of the connection between asbestos and mesothelioma is ongoing. Funnel plots show the possibility of bias in publications and there is a large degree of variability between studies. However, it is still evident that occupational exposure to asbestos is the most significant risk factor for mesothelioma.
Genetics
Mesothelioma is an uncommon disease caused by malignant mesothelial cell that expand beyond control and invade surrounding tissues. It can also spread throughout the body via the blood or lymphatic system, and affect other organs. Asbestos is the main cause, but it is not the sole cause. Other genetic and environmental factors can also cause the disease.
In a few cases mesothelioma has been found in people who had no direct exposure to asbestos. They are known as non-occupational mesothelioma patients. They usually had indirect exposure from the handling of contaminated clothing or home items by an asbestos-exposed individual in their home. It is possible to be diagnosed with mesothelioma following inhaling asbestos fibers from clothing of a family member. Research has shown that this form of mesothelioma is more likely to have a longer latency period and is more likely to be found in women than males.
Scientists are examining the possibility that mesothelioma-related genetic predispositions could be a factor in its development. Recent studies have revealed that mutations in a gene called BAP1 increases the risk of mesothelioma developing in those who have been exposed to asbestos. This finding is significant as it could lead to improved screening methods for those who are at high risk of developing mesothelioma.
Researchers have discovered that a range of genes are involved in mesothelioma. Certain of these genes are involved in reducing the growth of tumors, and are often mutated or altered in mesothelioma patients. These genes include large tumor suppressor 2 (LATS2) and NF2.
A family history of the disease can increase the risk. This is due to the fact that certain genes, such as the BAP1 one, can be inherited from a parent. Asbestos was a common ingredient in the military for many years, and veterans have the highest mesothelioma rates compared to other occupational groups. Those who served in the Navy and on ships were particularly at greatest risk due to the high exposure to asbestos in insulation, fireproofing materials and shipbuilding.
