Mesothelioma and Non Asbestos Exposure
The majority of mesothelioma cases occur on the lung linings and abdomen. This rare cancer may develop in the linings of the heart or testes (pericardium).
Asbestos exposure is the main risk factor for mesothelioma. However, some patients diagnosed with mesothelioma may not have an asbestos-related history.
Exposure to Asbestos
Asbestos is a naturally occurring mineral that was previously used in construction and industrial products worldwide. Workers working in asbestos-related industries were exposed asbestos each day. Asbestos fibres can lodge in the lungs and cause progressive lung disease. This is known as asbestosis. As time passes, the asbestos fibers trapped in the lungs may cause mesothelioma. Asbestos can also be breathed in or consumed and the risk of developing mesothelioma and other asbestos-related illnesses increases depending on the duration and amount of exposure.
The majority of mesothelioma cases are the result of occupational exposure. Asbestos was used in various trades, such as construction, insulation and electrical work, as well as automobile maintenance and pipefitting. These professions are usually heavily populated by males and, as a result mesothelioma cases involving males comprise 75-80 percent of all cases reported. The elimination of asbestos in the United States, and other first-world nations has reduced on-the-job contamination. This has led to an increase in cases, with non-occupational exposure increasing.
Non-occupational mesothelioma may occur when asbestos is released from the work environment or found in the home or school environment. The secondhand exposure can also trigger it, for example when a family member touches the clothing of an asbestos worker. This type of exposure can cause symptoms like chest pain or shortness of breath that are often mistaken for heart conditions or lung diseases.
Some studies have linked non-occupational exposure to mesothelioma, but the results aren't consistent. The studies were conducted with a small number of participants, and the variability between studies was high. Further research is needed to establish the connection between non-occupational exposure and mesothelioma.
People who have been exposed to non-occupational asbestos should discuss their asbestos background with their physician. nevada asbestos attorneys should request mesothelioma testing when they are concerned and request a referral to a specialist. Mesothelioma specialists can offer patients the best care and treatment options to improve their chances of survival. They will analyze medical records and perform imaging tests to identify mesothelioma. They will also provide guidance on how to file mesothelioma suit to receive compensation from an asbestos trust funds.
Secondhand Exposure
While exposure to asbestos is the leading cause of mesothelioma, it's not the only way to get this cancer. In fact, there's some evidence that suggests that people may develop mesothelioma even though they never directly handled asbestos or worked in an industry that involved asbestos-related activities. This is referred to as secondary asbestos exposure, or non-occupational asbestos exposure.
Asbestos fibers are tiny and can stick to clothing, hair and skin. Workers may carry harmful fibers in their work clothes at home and then transmit them to family members. The asbestos fibers can cause mesothelioma if they are inhaled or consumed.
This form of mesothelioma is more common in women, and it usually occurs in the lung. It can also affect the chest wall or abdomen. The most commonly reported symptoms is breathlessness (dyspnea) and it may be coupled with other signs like fluid in the lungs, or a swelling in the scrotum.
Pleural mesothelioma refers to the name given to mesothelioma which occurs in the lungs. Peritoneal mesothelioma is the term used for mesothelioma which affects the stomach wall or the chest wall. A person with this type of mesothelioma can be afflicted by a variety such as abdominal pain, difficulty breathing and constipation.
A number of studies have shown that even those who have no prior previous history of exposure to asbestos can still develop mesothelioma as a result of exposure to asbestos through secondhand fibers. The people who were affected usually lived with someone who had been exposed to asbestos. They could have handled the clothing of the worker, or they might have had other exposure to asbestos.
Veterans are at a greater risk of developing mesothelioma due to asbestos that was extensively used in military bases, vehicles and ships. The Navy is especially at risk since asbestos was used to insulate the hull of the ship as well as to protect gun turrets. Asbestos was also taken home by sailors after their jobs on ships that were contaminated.
Environmental Exposure
Mesothelioma has been linked to a variety of substances. The disease is still most often associated with asbestos exposure. Asbestos is a mineral that occurs naturally was used in the manufacturing process for a long time. It is resistant to heat and strong, making it ideal for insulation, brakes, shingles, flooring and other products. Asbestos is broken down to dust, which can be inhaled and swallowed. These fibers can stay in the lungs and stomach for many years, triggering mesothelioma-related symptoms.
The most frequent symptoms of mesothelioma are chest pain, abdominal discomfort and difficulty breathing. Asbestos exposure can cause these symptoms to persist for up to 60 years. These symptoms could be mistaken for other diseases, therefore it is important to see an expert if you experience these symptoms. It is also critical to tell your doctor about your previous history of asbestos. This will help avoid an incorrect diagnosis and ensure that you receive the correct treatment.
Mesothelioma that is caused by exposure to asbestos is more frequent in those who have worked directly with the material, but it can also be a problem for loved ones of those exposed. This is referred to as secondary exposure. Family members may inhale or ingest asbestos fibers from a worker's shoes, clothing or even tools. These particles could also be brought to home by someone who is wearing or having hair. This is the reason mesothelioma sufferers and their families should always take care to wash their clothing properly after working with asbestos.
There is a substantial amount of research that shows an association between nonasbestos and mesothelioma. However there is no definitive conclusions about the impact of other agents. For instance, there is some evidence that the zeolites erionite and chrysotile can cause mesothelioma. Erionite is found in soil and rocks from certain areas in Turkey where the incidence of pleural mesothelioma is high.
The study of the relationship between nonasbestos and mesothelioma continues. Funnel plots show the possibility of bias in publications and there is a large level of heterogeneity between studies. It is clear that asbestos exposure is the main mesothelioma-related risk factor.
Genetics
Mesothelioma is a rare disease caused by malignant mesothelial cells which expand beyond control and invade surrounding tissues. It can also spread through the body through the blood or lymphatic system, and affect other organs. Asbestos is the most common reason, but it's not the only factor. Other environmental and genetic factors can also trigger the condition.
Certain cases of mesothelioma have been reported in people who were not exposed directly themselves to asbestos. These are referred to as non-occupational mesothelioma sufferers. They are typically exposed indirectly by the handling of harmful household items or clothing by someone who was exposed to asbestos 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 tends to have a longer latency period and is more likely to affect women than men.
Scientists are currently investigating the possibility that a genetic predisposition to mesothelioma could play a role in the development of the disease. Recent studies have shown the mutation in BAP1 genes increases the risk of mesothelioma among asbestos-exposed patients. This is a significant finding because it could be the basis for improved screening procedures for those at risk of developing mesothelioma.
Researchers have discovered that a number of genes are involved in mesothelioma. These genes are frequently altered in mesothelioma and suppress the growth of tumors. These genes include large tumor suppressor 2 (LATS2), and NF2.
A family history of the disease increases the risk. This is due to certain genes, including BAP1 BAP1 one, can be inherited from an individual parent. Veterans have the highest rates of mesothelioma when compared to other occupational categories due to asbestos being used extensively in the military. People who were in the Navy and on ships were at greatest risk due to the high exposure to asbestos in fireproofing, insulation materials, and shipbuilding.
