Malignant mesothelioma, a rare form of cancer is a disease in which cells are cancerous (malignant) in the sac lining the chest (the pleura) or the lining of the abdomen (the peritoneum). Most people with malignant mesothelioma have worked in places where they breathed asbestos breathing.
You should see a doctor if you have shortness of breath, chest pain or pain or swelling in the abdomen. If you have symptoms, your doctor may send you to do an x-ray of the chest or abdomen.
The doctor may look inside the chest cavity with a special instrument called a thoracoscope. To do this, will make an opening through the chest wall and install the thoracoscope into the chest between two ribs. This test, called thoracoscopy, is usually performed in a hospital. Before the test, be given a local anesthetic (a drug that causes loss of feeling for a short period of time.) You may feel some pressure, but usually no pain.
The doctor may look inside the abdomen (peritoneoscopy) with a special tool called peritoneoscope, which is inserted into an opening in the abdomen. Usually, this test is also carried out in the hospital. You are given a local anesthetic before performing the test.
If abnormal tissue is found, the doctor will remove a small piece to be submitted to an analysis by microscope to determine the presence of cancer cells. This process is called a biopsy. Biopsies are usually done during the thoracoscopy or peritoneoscopy.
Your chances of recovery (prognosis) depends on the size of cancer, its location, how far it has spread, the appearance of cells under the microscope, how the cancer responds to treatment and patient age.
