Facts about the Malignant Peritoneal Mesothelioma
Mesothelioma can be benign or malignant. It is divided into four types based on their location: pleural, pericardial, testicular and peritoneal mesothelioma. In this article, we will give you some facts about malignant peritoneal mesothelioma.

Malignant Peritoneal Mesothelioma: Facts about the Malignant Peritoneal Mesothelioma

What Is It?

To put it simply, it is a type of mesothelioma which forms on the lining of the abdomen. Of all mesothelioma cases, the peritoneal mesothelioma accounts for less than a fifth of the total. The current most effective treatment for this mesothelioma is surgery combined with heated chemotherapy. Immunotherapy is also available as well.

The Cause

The cause of malignant peritoneal mesothelioma is ingesting asbestos fibers. Currently, mesothelioma researchers don’t know how exactly asbestos fibers can reach the abdomen and cause cancer but many theories have been developed.


There are many symptoms of peritoneal mesothelioma. Some of the most common symptoms include:
  • Sudden, unexplained weight loss
  • Fatigue
  • Nausea/vomiting
  • A feeling of fullness
  • Abdominal swelling
  • Abdominal pain
  • Night sweats
  • Fever
  • Anemia
  • Irregular bowel habits
  • Constipation
  • Diarrhea

How It Is Diagnosed

Next, how malignant peritoneal mesothelioma is diagnosed. There are three ways to diagnose peritoneal mesothelioma: blood tests, imaging scans, and biopsies.

Blood Tests

This test is done in order to reveal cancer-related biomarkers

Imaging scans

The scan is done to show the location as well as the size of the tumors


Biopsies are done to know the type of cancerous cells.


Peritoneal mesothelioma is divided into three stages.

Stage 1

In this stage, the cancerous tissue is minimal, cancer doesn’t reach lymph nodes and the tumors are still within the abdominal lining.

Stage 2

In this stage, the cancerous tissue has grown but it is still moderate, the tumors are still inside the abdominal lining.

Stage 3

In this stage, the cancerous tissue has grown extensively, the tumors may have spread outside the abdominal lining, to the lymph nodes or both.
