This form of the disease impacts the membrane that lines the abdominal cavity, the peritoneum. It is also unclear how this form of the disease develops. The theory for pericardial mesothelioma that tiny asbestos fibers travel through the bloodstream is also applicable for the peritoneal variety. It is also quite possible that asbestos fibers work their way to the abdominal wall through the digestive tract and that they are introduced to the body through eating or drinking.
Asbestos fibers travel through the air like dust and pollen. They could certainly find their way to consumable items on a jobsite. Regardless of the source, the impact of asbestos on the peritoneal membrane is the same. Over time they act as an irritant which results in prolonged inflammation, eventually leading to the development of uncontrolled cancerous cell growth.
Fifteen to twenty percent of all mesothelioma cases are peritoneal. The fact that it is more common than pericardial mesothelioma would suggest that the causal theory based on ingestion makes sense. Lung cancer can also be a secondary development of peritoneal mesothelioma; in addition one of the rare forms of peritoneal mesothelioma can impact the testicles. The membrane within the scrotum is an extension of the peritoneal mesothelium.
Symptoms usually begin with abdominal pain as the fluid buildup caused by the mesothelioma cells begins to impact the abdominal cavity. It can also be accompanied by shortness of breath and a cough, although these symptoms are less common. What peritoneal mesothelioma does share with other types of the disease is a lag of some months between manifestation of the symptoms and a diagnosis.
