Some patients develop excessive fluid in the abdomen. This is called an effusion or ascites. A doctor may take a sample of such fluid to diagnose peritoneal mesothelioma.

The symptoms of this cancer may include stomach pain, weight loss, nausea, vomiting, hernia, fluid in the abdominal cavity or a mass in the abdomen.
