Mesothelioma most commonly affects the tissue surrounding the lungs (pleura). This type is called pleural mesothelioma. Other, more rare types of mesothelioma affect tissue in the abdomen (peritoneal mesothelioma), around the heart, and around the testicles. 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.

Mesothelioma is cancer of the mesothelium, a membrane that lines the inside of body cavities, such as the abdomen or chest. Three out of four cases of mesothelioma disease begin in the chest cavity. Mesothelioma can also begin in the abdominal cavity and around the heart. Mesothelioma is a cancer caused by asbestos.
It most often occurs in the lining of the lungs or abdomen. Average life expectancy is 18 to 31 months after diagnosis, but prognosis may improve with treatment. Symptoms may include chest pain, shortness of breath, and general fatigue. Blood levels of three substances (fibulin-3, osteopontin, and soluble mesothelin-related peptides (SMRP) are usually higher in people with mesothelioma.
Peritoneal mesothelioma can form in the abdomen when inhaled asbestos fibers are expelled by coughing and then swallowed. Most people diagnosed with mesothelioma were exposed to asbestos while doing certain manual labor or serving in the military. Physicians who focus on mesothelioma in specialized treatment centers give patients the best chance of prolonging life and improving the prognosis. The most common way doctors decide the stage of pleural mesothelioma is through the international tumor nodule metastasis staging system (TNM).
Crocidolite fibers, which are a subtype of amphibole fibers, are most commonly associated with mesothelioma in humans. It is also possible that there are other causative agents that cause the development of mesothelioma, such as radiation and possibly certain chemicals or viruses. Mesothelioma can be difficult to diagnose, as the symptoms are often the same as those of other diseases and mesothelioma cells can be difficult to identify. When fibers are deposited in the peritoneum, which is the lining of the abdominal cavity, peritoneal mesothelioma can develop.
Having mesothelioma and treatment can change the way you feel about yourself, other people, your relationships, and sex. The most common form of mesothelioma is pleural mesothelioma, which develops in the mesothelium of the lungs. The risk of developing mesothelioma is closely related to the amount of asbestos a person is exposed to and the duration of exposure. The most common way doctors decide the stage of peritoneal mesothelioma is the peritoneal cancer index (PCI).
We offer assistance to those facing mesothelioma treatment decisions and health-related financial difficulties. In general, only a small fraction of people exposed to asbestos or other causative agents of mesothelioma actually develop the disorder. Eating a nutrient-rich diet, staying healthy, undergoing cancer treatments, and making healthier lifestyle choices can improve the prognosis and well-being of malignant mesothelioma. .
