The cancer of the lining of the abdominal cavity is called peritoneal mesothelioma. It is not as common as pleural form; it comprises an estimated one fifth to one third of all diagnosed mesothelioma cases. This report of the Surveillance, Epidemiology and End Results (SEER) approximates the number as 54. 7% male and 45. 3% female, with the age ranging from 65 to 69. The period of latency is shorter for patients exposed in asbestos, the symptoms appearing after 20 to 30 years from exposure; the usual latency period for pleural mesothelioma is 30 to 40 years.

Peritoneal Mesothelioma Symptoms

At the time of presentation, symptoms of peritoneal mesothelioma includes abdominal mass, abdominal pain, enlarged abdominal girth, fluid in the abdomen (ascites), distention of the abdomen, weight loss, fever, anemia, fatigue and digestive disturbances. For a few months before a confirmed diagnosis, some patients even complain of symptoms that are non-specific. Incidentally, peritoneal mesothelioma is found in a percentage of cases once the patient has other health complaints such as hernia, gallbladder or pelvic mass.

Doctors who have experiences in this field have noted that typically, patients have these symptoms six months to two years prior to the diagnosis. Men often come to the doctor complaining of a bulge in the groin (hernia) or around the belly button (umbilical hernia). For women, the first sign of a problem often occurs after a pelvic test when a tumor mass have been discovered.

In later stages of peritoneal mesothelioma, among the symptoms are increased occurrences of blood clots and obstruction of the bowel. There is a noticeable increase on the platelet count for 50% of peritoneal patients but this may be caused by various disorders, so this is actually of little help in the diagnosis. Low albumin level and anemia can also be among the symptoms. tarceva
