Which factor is known to cause mesothelioma?

Mesothelioma is a rare and aggressive type of cancer that affects the mesothelium, which is the protective lining of various organs. The primary known cause of mesothelioma is exposure to asbestos. Asbestos is a naturally occurring mineral that was commonly used in construction and various industrial applications due to its durability and resistance to heat. When asbestos fibers are inhaled or ingested, they can become trapped in the body's tissues, leading to inflammation, scarring, and ultimately cellular damage that can result in mesothelioma.

Research has consistently shown a strong correlation between asbestos exposure and the development of mesothelioma, with a long latency period often seen between exposure and the onset of the disease. While other factors like radiation exposure, smoking, and certain viral infections have been studied in relation to cancer, they do not have the same established and significant connection to mesothelioma specifically as asbestos exposure does. This understanding underscores the importance of restricting asbestos use and implementing safety measures in environments where asbestos is present to prevent its harmful effects.
