Mesothelioma: Overview
Mesothelioma is an aggressive cancer that affects the lining of the lungs, abdomen and heart. It is caused by exposure to asbestos fibers and is typically diagnosed in people over the age of 65. Although there is no known cure, there are treatments available to help manage symptoms and prolong life.
Can Mesothelioma Not Be Caused By Asbestos?
Mesothelioma is almost always caused by exposure to asbestos, a mineral fiber found in many building materials, insulation, auto parts, and other products. Inhaling or ingesting small asbestos fibers can cause the fibers to become lodged in the mesothelium, the thin membrane that surrounds and protects the internal organs. Over time, these fibers can cause DNA damage and lead to the formation of cancerous cells. As such, mesothelioma is almost always caused by asbestos exposure.
However, it is possible for mesothelioma to arise without exposure to asbestos. For instance, some cases of mesothelioma are caused by genetic mutations that occur naturally. These mutations can cause cells to divide abnormally and lead to cancer. In addition, some studies suggest that long-term exposure to certain viruses, such as the Epstein-Barr virus, may increase the risk of mesothelioma.
Conclusion
In conclusion, mesothelioma is almost always caused by exposure to asbestos fibers. However, in rare cases, mesothelioma can occur without exposure to asbestos, or due to long-term exposure to certain viruses. It is important to be aware of the potential causes of mesothelioma and to take steps to reduce the risk of exposure to asbestos.
