What causes mesothelioma other than asbestos?

Causes of non-asbestos-related mesothelioma have been suggested. A volcanic mineral, known as erionite, can also cause mesothelioma. Erionite was first associated with the disorder due to a large increase in the incidence of mesothelioma in Cappadocia, central Anatoli region of Turkey. Mesothelioma is caused by exposure to asbestos.

When asbestos fibers are inhaled or ingested, they cause scarring and inflammation, which can develop into a mesothelioma tumor. Research has shown that 80% of all cases of mesothelioma are caused by known exposure to asbestos. There are no other proven causes of mesothelioma. Researchers continue to investigate other possible causes and risk factors, such as exposure to the SV40 virus or minerals that look like asbestos.

Mesothelioma was practically unknown until the 20th century. Mesothelioma incidence rates increased as industries expanded the use of. The only proven cause of mesothelioma is exposure to asbestos. Most risk factors for mesothelioma involve different sources of exposure to.

Other risk factors, such as the genes you inherit or exposure to the simian virus 40, known as SV40, have not been shown to cause mesothelioma. Other potential risk factors that remain unproven causes of mesothelioma include genetic factors and exposure to radiation, zeolite minerals, and the polio vaccine between 1955 and 1963 that was contaminated with simian virus 40 (SV40). Asbestos fibers take an average of 20 to 50 years to convert normal mesothelial cells into mesothelioma cancer cells. This time lag between exposure and the development of the disease is known as the latency period.

Asbestos fibers take decades to cause damage that leads to mesothelioma, but once mesothelial cells become cancerous, they can quickly form mesothelioma tumors that grow and spread within months to a few years. According to the American Cancer Society, 80% of mesothelioma cases are caused by known exposure to asbestos. Studies have shown that radiation treatment for other types of cancer or certain genetic markers may increase the risk of developing mesothelioma. However, asbestos is still the only proven cause of the disease.

About 8 out of 10 people with mesothelioma have been exposed to asbestos. When asbestos fibers are inhaled, they travel to the ends of the small airways and reach the pleura, where they can cause inflammation and scarring. This can damage the cells' DNA and cause changes that cause uncontrolled cell growth.

If ingested, these fibers can reach the abdominal lining, where they may play a role in causing peritoneal mesothelioma. However, most people exposed to asbestos, even in large numbers, do not get mesothelioma. Most mesotheliomas are thought to be related to asbestos exposure. Asbestos is a mineral found naturally in the environment.

Asbestos fibers are strong and heat resistant, making them useful in a wide variety of applications, such as insulation, brakes, shingles, flooring and many other products. Most cases of mesothelioma are caused by exposure to. But there are other ways that mesothelioma cancer is not caused by asbestos. Below are rare ways you can develop this disease that does not involve exposure to asbestos.

The diagnosis of mesothelioma without exposure to asbestos is rare. Exposure to asbestos is the number one risk factor and the most common underlying cause of mesothelioma. There are possible explanations for diagnoses without known exposure. Mesothelioma, like most cancers, results from a combination of genetic and environmental exposures.

The genetic factor may explain why some people may experience prolonged exposure to asbestos, but cannot develop cancer. Mesothelioma is strongly associated with prolonged exposure to asbestos. People who worked in jobs with regular exposure to asbestos-containing materials have higher rates of mesothelioma. Even people exposed to secondhand asbestos have a higher risk of being diagnosed with mesothelioma.

Second-hand exposure includes contact with the fibers of a family member's clothing, for example. Another mystery of mesothelioma without exposure to asbestos is the cause of peritoneal mesothelioma. The second most common type of this cancer, research indicates that half of all cases of peritoneal mesothelioma occur in people with no known exposure to asbestos. By comparison, at least 80% of people with pleural mesothelioma have a history of exposure to asbestos.

We know that asbestos causes most cases of pleural mesothelioma. This starts in the two sheets of tissue that cover the lungs, called the pleura. Being exposed to large amounts of asbestos for a long period of time increases the risk of mesothelioma. Many people with mesothelioma in the abdomen (peritoneal mesothelioma) have also been exposed to asbestos.

The authors concluded that germline BAP-1 mutated mesotheliomas are associated with longer survival than usual sporadic mesothelioma. Mesothelioma is a cancer that most often begins in the sheets of skin-like tissue that cover each lung (the pleura). Researchers believe that the main reason for the higher incidence rate of mesothelioma with exposure to erionite compared to asbestos is due to the larger surface area of erionite. Doctors are working on ways to detect mesothelioma early in its development because the treatment is most effective at an early stage.

The signs and symptoms of other types of mesothelioma are not clear, since these forms of the disease are very rare. Considering the high concentration of erionite fibers in North America, as noted above, it is perhaps not surprising that a high incidence of lung cancer and malignant mesothelioma has been identified in 1 rural area with erionite contamination. Most people diagnosed with mesothelioma were exposed to asbestos while doing certain manual labor or serving in the military. Malignant mesothelioma (Me-zoe-thee-lee-o-muh) is a type of cancer that occurs in the thin layer of tissue that covers most internal organs (mesothelium).

For workers highly exposed to commercial forms of amphibulous asbestos, between 2% and 18% have developed pleural mesothelioma. Therefore, it has been speculated for some time that asbestos alone may not be enough to cause mesothelioma and that other factors may be involved, either as cocarcinogens or as mechanisms independent of the cause of cancer. Germline mutations of BAP-1 are inherited in an autosomal dominant manner and confer a high risk of mesothelioma in affected individuals and families. Roughly speaking, between 60 and 90% of mesotheliomas in US women (pleural and peritoneal sites, respectively) and a substantial proportion of peritoneal mesotheliomas in men are probably not related to asbestos.

Currently, the majority of pleural mesotheliomas (70 to 90%) in men in Europe and North America are attributable to exposure to asbestos; for peritoneal mesothelioma the proportion is lower. Experimental animal studies have confirmed the high carcinogenic potential of erionite, including the production of malignant mesotheliomas. In general, there is consistent evidence that radiation is a risk factor for malignant mesothelioma in directly irradiated tissues and, to a lesser extent, in tissue remote from the target area. In North America, few mesotheliomas in women anywhere are attributable to asbestos exposure, but in Europe the proportion is higher and varies considerably by location.
