Peritoneal mesothelioma

The most common symptoms of peritoneal mesothelioma are abdominal swelling and pain due to ascites (a buildup of fluid in the abdominal cavity). Other features may include weight loss, fever, night sweats, poor appetite, vomiting, constipation, and umbilical hernia.If the cancer has spread beyond the mesothelium to other parts of the body, symptoms may include pain, trouble swallowing, or swelling of the neck or face. These symptoms may be caused by mesothelioma or by other, less serious conditions.

Tumors that affect the abdominal cavity often do not cause symptoms until they are at a late stage. Symptoms include:

Abdominal pain
Ascites, or an abnormal buildup of fluid in the abdomen
A mass in the abdomen
Problems with bowel function
Weight loss
A mesothelioma does not usually spread to the bone, brain, or adrenal glands. Pleural tumors are usually found only on one side of the lungs.
