What is malignant mesothelioma?

Malignant mesothelioma is a malignant tumor that occurs in the mesothelial cells that cover the inner surface of the body cavity and occurs in the pleura, peritoneum, pericardium, and very rarely in the testicular sheath. 80% of all mesothelioma is the pleura and 10-20% is the peritoneum.
Most people who develop mesothelioma have worked or lived in an environment that often inhales asbestos. The period from inhalation of asbestos to the occurrence of malignant mesothelioma is very long and is said to occur after 25 to 50 years (on average about 40 years).
Symptoms include chest pain, dyspnea, and abdominal bloating, but early symptoms may not be present.

Diagnosis Of Malignant Mesothelioma

  • If a medical checkup reveals a shadow of the chest or if the above symptoms are prolonged, the patient will be examined and a chest x-ray or CT will be performed.
  • If a pleural mesothelioma is suspected, a thoracoscopic pleural biopsy is done and the tissue of the lesion is actually taken to check for malignant cells.
  • When water accumulates in the abdomen (ascites) and peritoneal mesothelioma is suspected, a diagnosis is made by laparoscopy.
  • If malignant mesothelioma is confirmed, the whole body is examined by CT or MRI for the spread of cancer cells and the presence or absence of metastases.


There are surgical treatment (surgery), drug therapy (anticancer drug treatment), and radiation therapy. The appropriate treatment is determined according to the extent of malignant mesothelioma, the status of metastasis, and the patient’s condition. In some cases, several treatments may be combined.
