Peritoneal Mesothelioma and Malignant Mesotheliomas

Peritoneal mesothelioma is less common than pleural mesothelioma, but both of these typically malignant mesotheliomas can be just as tragic. Peritoneal mesothelioma begins in the abdominal cavity, as opposed to the lungs and pleural areas of pleural mesothelioma. “Peritoneal” means it has to do with the peritoneum, which is a membrane that surrounds the abdominal area. “Pleural” refers to the pleura which is a membrane that surrounds the lungs. There is also a “pericardial” mesothelioma which targets the heart membrane first.

The lungs, abdominal area and heart all have a membrane made up of mesothelial cells, named the mesothelium. A cancerous attack of these membrane areas are mesotheliomas. Asbestos is the cause of peritoneal mesothelioma, pleural mesothelioma and pericardial mesothelioma in well over 90% of the cases. There are a few rare recorded cases of malignant mesothelioma when asbestos exposure was not identified. If you have been exposed to asbestos, there is a high chance you will suffer from an asbestos-caused disease such as asbestosis or pleural plaques. However, not all asbestos-caused diseases are fatal.

Peritoneal mesothelioma, pleural mesothelioma and pericardial mesothelioma can be fatal malignant mesotheliomas which spread uncontrollably, or they can be benign, when the tumor stays where it is and can likely be removed. Unexplainable weight loss is a mesothelioma symptom which may occur in as many as 90% of benign and malignant mesothelioma. Generally, benign mesothelioma tends to show less symptoms than malignant mesothelioma. Mesothelioma symptoms for peritoneal mesothelioma almost always includes abdominal pain. This is because there is excess fluid between the peritoneal membrane and the abdomen walls. Pleural mesothelioma has excess fluid in the pleural area and this causes shortness of breath and chest pain.

The mesothelioma symptoms of pleural mesothelioma and pericardial mesothelioma are not as outwardly visible as the symptoms of peritoneal mesothelioma. In peritoneal mesothelioma, the abdomen can appear larger. Tumor masses may be visible, but external tumor visibility only occurs in a minority of peritoneal mesothelioma cases. Nausea is a common mesothelioma symptom with peritoneal mesothelioma, and the abdominal area will also be very tender.

In a healthy peritoneal area between the membrane and the wall, the peritoneal fluid helps the intestines move food. In peritoneal mesothelioma however, excess fluid causes bowel obstruction. The mesothelioma symptoms of extra fluid and bowel obstruction both contribute to abdominal pain. The bowel obstruction can also produce mesothelioma symptoms of constipation and diarrhea. Many peritoneal malignant mesothelioma patients have reported mesothelioma symptoms of a burning sensation in the abdomen. Mesothelioma symptoms for peritoneal malignant mesothelioma may not surface for 20-30 years after asbestos exposure, but it generally surfaces sooner than pleural mesothelioma.

Peritoneal mesothelioma is fortunately rare, however its rarity sometimes makes it harder to diagnose. The symptoms are similar to hernias and gall bladder problems, and identifying peritoneal mesothelioma in a CT scan is difficult. The medical industry is aware that asbestos-related diseases will be escalating over the upcoming years, and treatment for peritoneal malignant mesothelioma is undergoing many clinical trials. If you have been exposed to asbestos and have unexplainable abdominal pain and are experiencing unexplained weight loss, begin preliminary testing for peritoneal mesothelioma. The sooner the testing begins, the higher the chances for symptomatic relief, and hopefully today’s mesothelioma clinical trials will lead to a mesothelioma cure in the future.
