Mesothelioma Cancer, Mesothelioma Diagnosis

Malignant mesothelioma is the most serious of all asbestos-related diseases. Although uncommon, mesothelioma cancer is no longer considered rare. The primary cause and risk factor for mesothelioma is exposure to asbestos.

Making a correct mesothelioma diagnosis is particularly difficult for doctors because the disease often presents with symptoms that mimic other common ailments

. There is no known cure for mesothelioma, but treatments such as surgery and chemotherapy have helped to improve the typical mesothelioma prognosis.

Pleural mesothelioma (affecting the lung’s protective lining in the chest cavity) represents about three quarters of all mesothelioma incidence. Peritoneal mesothelioma which affects the abdominal cavity and pericardial mesothelioma, which affects the cardiac cavity comprise the remainder. Testicular mesothelioma is extremely rare and is typically presents with metastases of the peritoneal variety. There are three recognized mesothelioma cell-types. Between 50 and 70% of all mesotheliomas are of the epithelial variety. While prognosis is generally poor, these are considered less aggressive than sarcomatoid mesothelioma and biphasic mesothelioma, which comprise the remainder of diagnoses.
The cavities within the body encompassing the chest, abdomen, and heart are surround by a membrane of cells known as the mesothelium. Mesothelial cells assist in general organ functions. The mesothelium is particularly important to organs which are commonly in motion, such as expansion or contraction of the lungs, stomach, or heart. Lubrication from the mesothelial cells allows free range of motion within the body. The mesothelium of the chest, abdomen, and cardiac cavity are called the pleura, the peritoneum, and the pericardium, respectively. Each of these groupings of mesothelial cells are extremely critical to the functions of the body structures which they encompass.
