Mesothelioma and Non Asbestos Exposure
Most commonly, mesothelioma develops on the linings of the lungs and abdomen. The rare cancer may also develop 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 may 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 across the globe. Workers working in asbestos industries were exposed to asbestos every day. Asbestos fibres can become lodged in the lungs and cause progressive lung diseases. This is known as asbestosis. Over time, these fibers that are trapped in the lungs may cause mesothelioma. Asbestos is also inhaled or eaten, and the risk of mesothelioma and other asbestos-related diseases increases depending on the duration and amount of exposure.
The majority of mesothelioma cases result from occupational exposure. Asbestos was used in many trades, including construction, insulation electrical work, automotive maintenance and pipefitting. Since these occupations are predominantly male-dominated 75-80% of mesothelioma cases are diagnosed in males. The gradual elimination of asbestos in the United States, and other first-world countries has reduced the risk of contamination. This has led to an increase in cases, with asbestos exposure outside of the workplace increasing in frequency.
Non-occupational mesothelioma can develop when asbestos is released from a work environment or found in the school or home environment. Exposure to asbestos from the outside can cause it, such as when a family members touches the clothing of an asbestos worker. The people who suffer from this type of exposure may have symptoms such as breathing problems or chest pain, which is commonly mistaken for heart or lung conditions.
Certain studies have linked mesothelioma to non-occupational exposure, but the results are different. Many of these studies have been conducted with a small sample size, and within-study heterogeneity has been high. Further research is needed to establish the connection between exposure to non-occupational sources and mesothelioma.
Those who have been exposed to asbestos in non-occupational settings should speak to their doctor regarding their asbestos-related background. If they are concerned, they should ask for a mesothelioma test and a referral to a specialist. Mesothelioma specialists can provide patients with the best treatment and care options to improve their odds of survival. They will review medical records and conduct imaging tests to diagnose mesothelioma. They will also provide guidance on how to file mesothelioma suits to receive compensation from an asbestos trust funds.
Secondhand Exposure
While asbestos exposure is the main cause of mesothelioma, it's not the only reason to develop this disease. There is some evidence that those who haven't handled asbestos or worked in industries that have asbestos-related activities can still develop mesothelioma. This is known as secondary or non-occupational exposure.
Asbestos fibers are very small, and they can stick to hair, clothing, skin and other surfaces. Workers may carry harmful fibers in their work clothes at home, and then transmit them to family members. These stray asbestos fibers can be swallowed or inhaled which can cause mesothelioma.
This type of mesothelioma is more common in women, and usually occurs in the lungs. However, it can be found in the abdomen or the chest wall. The most frequent symptoms is breathlessness (dyspnea) and it may be coupled with other signs like fluid in the lungs, or a swelling in the scrotum.
The mesothelioma that develops in the lungs is known as pleural mesothelioma. Peritoneal mesothelioma refers to the name for mesothelioma, which affects the stomach wall or the chest wall. A patient suffering from this type of mesothelioma may be afflicted by a variety such as abdominal pain, breathing difficulties and constipation.
According to milpitas asbestos attorneys , people who have not been exposed to asbestos in the workplace may still develop mesothelioma due to exposure through secondhand sources. They usually lived with someone who had been exposed to asbestos. They might have handled the garments of the worker or had other contact with asbestos.
Veterans are at a high risk of developing mesothelioma due to asbestos that was used extensively in military bases, vehicles and ships. The Navy is at a greater risk since asbestos was employed in the hull and gun turrets of ships to protect them from fire. In addition, sailors frequently brought home asbestos from their jobs aboard vessels that were contaminated with the substance.
Environmental Exposure
Mesothelioma has been linked to a variety of substances. The disease is often linked to asbestos exposure. Asbestos is a naturally occurring mineral that was used for many years in the manufacture of. The mineral is heat-resistant and tough, which makes it ideal for insulation, brakes, shingles flooring, and many other products. Asbestos is broken down to dust that can be inhaled and swallowed. These fibers may remain in the lungs or stomach for a long time, triggering mesothelioma-related symptoms.
The most frequently reported mesothelioma symptoms are breathing difficulties, abdominal pain and chest pain. Asbestos exposure can cause these symptoms to last for up to 60 years. It is essential to consult a doctor when you experience these symptoms. Informing your doctor about asbestos exposure is essential. This can prevent a wrong diagnosis and ensure that you receive the right treatment.
The most common mesothelioma victims from asbestos exposure are those who worked directly with asbestos however it is possible for loved family members to be affected. This is called secondary exposure. Family members can take in asbestos fibers or swallow them on a worker's clothes, shoes or tools. They could be sprayed on the to home by someone who is wearing or having their hair. It is for this reason that mesothelioma sufferers as well as their families must always clean their clothes after working with asbestos.
There is a large amount of research that suggests the connection between exposure to asbestos and mesothelioma. However there is no conclusive evidence yet on the role of other agents. There is some evidence to suggest that zeolites, namely erionite and chlorosotile are able to cause mesothelioma. Erionite is found in soil and rocks in certain parts of Turkey in which mesothelioma incidences are high in pleural mesot.
Research into the relationship between mesothelioma and exposure to nonasbestos is ongoing. Funnel plots have indicated the potential for bias in publication, and there is a high degree of heterogeneity between studies. However, it is still clear that occupational exposure to asbestos is the most important risk factor for mesothelioma.
Genetics
The mesothelioma-related rare disease occurs when malignant cells of mesothelium multiply uncontrollably and invade surrounding tissues. It can also spread through the body through the blood or lymphatic system, and affect other organs. Asbestos is the main cause, but it's not the sole cause. The condition could be triggered by other genetic and environmental factors.
Certain cases of mesothelioma have been seen in people who didn't directly expose themselves to asbestos. These are referred to as non-occupational mesothelioma victims. They are typically exposed through the handling of harmful household items or clothing by anyone who was exposed to asbestos in their home. It is possible to be diagnosed with mesothelioma following breathing asbestos fibers in the 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 be found in women than males.
Scientists are examining the possibility that mesothelioma-related genetic predispositions could play a role in the development. Recent studies have revealed that mutations in a gene called BAP1 could increase the risk of mesothelioma among people who are exposed to asbestos. This finding is significant as it could lead to improved screening methods for those who are at risk of developing mesothelioma.
Researchers have discovered that a variety of genes are linked to mesothelioma. These genes are usually mutated in mesothelioma and inhibit tumor growth. These genes include large tumor suppressor 2 (LATS2), and NF2.
People who have mesothelioma-related family history are at a higher chance of contracting the cancer. Certain genes, like BAP1 BAP1 which is passed down from parents. Veterans have the highest mesothelioma rates when compared to other occupational categories due to asbestos being used extensively in the military. Those who served in the Navy and on ships were at risk the most because of the extensive exposure to asbestos in insulation, fireproofing materials and shipbuilding.
