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.
Due to the long latency period of mesothelioma, approximately 20-50 years, 75% of the people who are diagnosed with the disease are seniors. The Mesothelioma Center works with those who are diagnosed and their families to help find local doctors, treatment centers and support groups.
