Mesothelioma of Types
Pleural mesothelioma is the most common type of malignant mesothelioma, comprising approximately 75 percent of all mesothelioma cases. This type develops in the lining of the lungs, called the pleura.
A disease that has only started to come to light in recent years, mesothelioma is a cancer that normally presents itself in malignant form and results in tumours in and around vital organs of the body. The definition of the word mesothelioma is literally cancer of the mesothelium (-oma being a medical term for cancer). The mesothelium is the sac that lines and protects vital organs such as the heart and the lungs, and this disease causes the cells of the lining to become abnormal and malignant.
Peritoneal mesothelioma develops in the abdomen’s peritoneum, a layer that covers the abdominal cavity and surrounds abdominal organs.
Pericardial mesothelioma develops in the pericardium, a membrane that surrounds the heart and provides protection and support to this organ.
Testicular mesothelioma, the rarest form of mesothelioma, develops in the lining surrounding the testicle, called the tunica vaginalis.
The result of asbestos exposure, mesothelioma comes in three forms: pleural mesothelioma; peritoneal mesothelioma; and pericardial mesothelioma. All three types have a variety of associated symptoms, and there are some symptoms that are common to all three types of the disease. In all cases of the disease, sufferers are unlikely to even realise that there is a problem until many years after they have actually contracted mesothelioma from regular exposure to asbestos.
The symptoms of all types of mesothelioma do not generally manifest for several decades after contraction. This can make the disease difficult to diagnose and all too often is too late to save the patient by the time a diagnosis is made.
