Malignant pleural mesothelioma often originates within the chest cavity and can, at times, involve the lung. This particular form of mesothelioma can metastasize to numerous organs in the body - even the brain - and tends to do so more frequently than not.
Pleural mesothelioma is not always easily detectable. Frequently, in the early stages of the disease, such as stage 1 mesothelioma, symptoms may be mild. Patients usually report pain in one area of the chest that never seems to go away, weight loss and fever. Occasionally, other symptoms are more severe and include problems with breathing due to fluid build up in the chest. A CT Scan of the chest area has proven to be the best test for identifying how far along the disease has progressed.
Frequently serum markers are used to diagnose of various forms of cancer. Mesothelioma cannot be diagnosed using this method as no serum markers currently exist. If high levels of hyaluronic acid are present it may be possible to distinguish mesothelioma types from other types of cancer or to determine the effectiveness of a treatment protocol.
The mesothelioma survival rate for patients diagnosed with pleural mesothelioma typically is not high as patients often do not live beyond seventeen months from the onset of symptoms. Only 8% of those with a mesothelioma diagnosis will live three to five years from the onset of mesothelioma symptoms.
