The Various Stages of Mesothelioma

Mesothelioma is a sort of lung cancer that is caused solely by exposure to asbestos.  Doctors sometimes divide the progression of cancer into four stages based on how far the cancer has spread.  The 4 mesothelioma stages are like this :

Stage I
In Stage I, the mesothelioma is confined to one side of the body.  At this stage, it is typically limited to the pleura.  The two pleura form a membrane that surrounds the lung, and are divided by a layer of lubricating liquid.  Mesothelioma in the pleura causes them to make more of this fluid than they need . 

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 gut ), or the heart.  It may affect the pleura on either side of the body.  It could also affect the chest’s lymph nodes ( part of the immune reaction that works to clear out 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 abdominal hole ).  It could also affect lymph nodes outside of the chest. 

Stage IV
In the last of the mesothelioma stages, the malignancy has gone through metathesis, that is, it has gone thru the blood vessels to spread to the organs a long way away from the chest and stomach. 

Symptoms due to mesothelioma rely on where it has spread to.  If it is limited 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 may cause trouble swallowing, unexpected weight loss, or barfing blood.swallowing, sudden weight loss, or vomiting blood.
