Peritoneal mesothelioma is the second-most common type of mesothelioma, accounting for 10 to 20 percent of all mesothelioma cases. About 3,000 new cases of mesothelioma are diagnosed annually in the United States and approximately 300 to 600 of these are peritoneal mesothelioma. Asbestos exposure is its primary cause and most cases take more than two decades to develop once asbestos fibers are inhaled or ingested. X-rays and other tests are used to detect peritoneal mesothelioma, but biopsies help confirm a diagnosis. Although the cancer is usually diagnosed in the later stages of development, treatment options are available to combat symptoms and improve prognosis.
Overall prognosis for peritoneal mesothelioma patients is less than one year. However life expectancy can increase with effective treatment and early detection. Some patients may be candidates for surgery that can send the cancer into remission, while others may elect to receive palliative measures that improve symptoms and quality of life. Working with a mesothelioma specialist can help patients receive the best possible care for their cancer and potentially improve prognosis.
