15 Astonishing Facts About Mesothelioma Non Asbestos Exposure Mesothelioma and Non Asbestos Exposure Mesothelioma typically develops in the lung lining (pleura) and abdomen (peritoneum). The rare cancer may also develop in the lining of the heart (pericardium) or in the testes. Asbestos is a major risk factor for mesothelioma. However, some patients diagnosed with mesothelioma may not have any history of asbestos exposure. Exposure to Asbestos Asbestos is a naturally occurring mineral that was previously employed in industrial and construction products all over the world. The workers in asbestos-related industries were exposed to asbestos each day. Asbestos particles can be trapped in the lungs, where they cause progressive lung disease. This is known as asbestosis. Over time, these fibers trapped in the lungs can also cause mesothelioma. Asbestos is also inhaled or consumed and the risk of mesothelioma and other asbestos-related diseases rises depending on the duration and amount of exposure. The majority of mesothelioma cases are the result of occupational exposure. Asbestos is a common ingredient in jobs, including electrical work and vehicle maintenance. Since these occupations are dominated by males 75-80% of mesothelioma cases are diagnosed in men. The gradual elimination of asbestos in the United States, and other first-world countries has reduced the risk of contamination. This has resulted in a shift in cases, with non-occupational exposure increasing. Non-occupational mesothelioma can develop when asbestos is released from the workplace environment or found in the home or school environment. It can also be caused by exposure to secondhand asbestos like when a family member wears the clothing of an asbestos worker who has been exposed. People who are exposed to this kind of exposure may experience symptoms such as shortness of breath or chest pain, which is often mistaken for lung or heart problems. Some studies have linked mesothelioma with non-occupational exposure, however the results vary. These studies were conducted with very few participants, and the variability between studies was substantial. Further research is needed to confirm the links between exposure to non-occupational sources and mesothelioma. Anyone who has been exposed to non-occupational exposure should discuss their asbestos history with their doctor. If they are concerned, they should seek for a mesothelioma test and a referral to a specialist. Mesothelioma specialists can offer patients the best care and treatment options to improve their odds of survival. They will look over medical records and conduct imaging tests to determine if mesothelioma is present. They will also provide guidance on how to file mesothelioma suits to get compensation from asbestos trust funds. Secondhand Exposure While asbestos exposure is the primary cause of mesothelioma not the only way to develop this disease. There is some evidence that people who have never had exposure to asbestos or worked in industries with asbestos-related activities may still develop mesothelioma. This is called secondary or non-occupational exposure to asbestos. Asbestos fibers are small and can adhere to clothing, hair and skin. Workers could carry harmful fibers in their work clothing at home, and then transmit them to family members. These stray asbestos fibers can be swallowed or inhaled which can lead to mesothelioma. This type of mesothelioma is more prevalent in women, and it usually occurs in the lungs. However, it can occur in the abdomen or the chest wall. The most frequent symptom is shortness of breath (dyspnea) and it may be coupled with other signs like fluid in the lungs, or a swelling in the scrotum. mesothelioma and asbestosis is the name used to describe mesothelioma that is found in the lungs. Peritoneal mesothelioma refers to the name for mesothelioma, which affects the stomach wall or the chest wall. This kind of mesothelioma may cause a number of symptoms, including abdominal pain, difficulty in breathing, and constipation. A number of studies have shown that people with no background of occupational exposure to asbestos may develop mesothelioma due to exposure to asbestos through secondhand fibers. Most often, these people have been living with someone who was exposed to the dangerous substance. They might have handled the garments of the worker, or they might have had other contact with asbestos. Veterans are at risk of developing mesothelioma because of the widespread asbestos used in military bases, ships and vehicles. The Navy is particularly at risk since asbestos was used to insulate the hull the ship as well as to protect gun turrets. Asbestos was also frequently brought home by sailors who had returned from their work on ships that were affected by asbestos. Environmental Exposure A variety of materials have been associated with mesothelioma. The disease is often associated with asbestos exposure. Asbestos, a naturally occurring mineral is used in the manufacture of products for a long time. The mineral is heat-resistant and strong, making it ideal for insulation, brakes, shingles flooring, and other products. When asbestos is broken down it produces dust which can be inhaled or swallowed. These fibers can stay in the lungs and stomach for a long time, triggering symptoms of mesothelioma. The most frequent mesothelioma-related symptoms are breathing difficulties, abdominal pain and chest pain. Asbestos exposure can cause these symptoms to persist for up to 60 years. The symptoms can be misinterpreted as other ailments, so it is important to see an expert if you experience these symptoms. It is also crucial to inform your doctor about your past history of asbestos. This will prevent a faulty diagnosis and ensure that you receive the proper treatment. Mesothelioma related to exposure to asbestos is the most frequent in those who have worked directly with the material however, it can also affect loved relatives of those who have been exposed. This is referred to as secondary exposure. Family members could breathe in asbestos fibers on the clothes of a worker's tools or shoes. These particles could be sprayed on the home by someone who is wearing or having hair. This is the reason mesothelioma sufferers and their families must be sure to clean their clothes properly after working around asbestos. There is a large amount of research that suggests a relationship between nonasbestos exposure and mesothelioma. However there aren't any definitive conclusions yet regarding the role played by other agents. There is some evidence to suggest that chlorosotile and erionite zeolites, can cause mesothelioma. Erionite is found in the soil and in the rocks of certain areas of Turkey, where mesothelioma incidences are high in pleural mesot. Research into the relationship between mesothelioma exposure and asbestos exposure is continuing. Funnel plots show the possibility of publication bias and there is a large level of heterogeneity between studies. However, it is still evident that asbestos exposure from work is the most important 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 through the body via the lymphatic or blood system, affecting other organs. Although asbestos is the primary cause of mesothelioma, it isn't the sole risk factor. The condition could be caused by other environmental and genetic factors. In some instances mesothelioma has been found in people who were not exposed to asbestos. These are referred to as non-occupational mesothelioma patients. They were usually exposed indirectly by the handling of harmful household items or clothing by someone who was exposed asbestos in their home. It is possible to be diagnosed with mesothelioma after inhaling asbestos fibers from the clothing of a family member. Studies have shown that this kind of mesothelioma has longer time to develop and is more likely to be found in women than males. Scientists are studying the possibility that mesothelioma-related genetic predispositions could play a role in its development. Recent studies have revealed that the mutation in BAP1 genes increases the risk of mesothelioma among asbestos-exposed individuals. This finding is especially important, as it could lead to improved screening procedures for those at risk of developing mesothelioma. Researchers have discovered a number genes that are related to mesothelioma. Certain of these genes are involved in suppressing tumor growth and are often altered or mutated in mesothelioma patients. These genes include the massive homolog 2 of tumor suppressor (LATS2) and the NF2. People with mesothelioma-related family history are at a higher chance of contracting the mesothelioma. This is due to certain genes, like BAP1 BAP1 one, can be inherited from an individual parent. Veterans have the highest mesothelioma rates compared to other occupational groups due to asbestos being used extensively in the military. Those who served on ships or in the Navy were at highest risk because of asbestos exposure in the construction of ships, insulation and fireproofing materials.
