Mesothelioma is a form of lung cancer that is caused exclusively by being exposed to asbestos. Doctors typically divide the progression of cancer into four stages based mostly on how far the carcinoma has spread. The 4 mesothelioma stages are like this :
Stage I
In Stage I, the mesothelioma is confined to the side of the body. At this time, it is generally limited to the pleura. The two pleura form a surface that surrounds the lung, and are separated by a layer of lubricating fluid. Mesothelioma in the pleura causes them to make more of this liquid than they require.
On rare occasions, Stage I mesothelioma may involve the lung itself, the pericardium ( the membrane that surrounds the heart ), or the diaphragm ( the muscle that separates the stomach from the chest ).
Stage II
In stage II, the mesothelioma has spread. It now involves the chest wall, the esophagus ( which connects the mouth to the belly ), or the heart. It may affect the pleura on either side of the body. It might also have an effect on the chest’s lymph nodes ( part of the immune reaction that works to filter foreign particles ).
Stage III
In stage III, the mesothelioma has spread further. It is now beyond the diaphragm and in the peritoneum ( the membrane that surrounds the intestinal hole ). It might also affect lymph nodes outside of the chest.
Stage IV
In the last of the mesothelioma stages, the tumor has gone thru spreading, that is, it has gone thru the blood vessels to spread to the organs a great distance away from the chest and stomach.
Symptoms caused by mesothelioma rely on where it has spread to. If it is restricted to a lung ( as is characteristic of early mesothelioma stages ), it may cause dry coughing and loss of breath. If it has spread to the peritoneum, it can cause fever, swelling, and bowel or urinary Problems. In the final stages, it can cause trouble swallowing, sudden weight reduction, or vomiting blood.swallowing, sudden weight loss, or vomiting blood.
