Mesothelioma Stages

Mesothelioma is a kind of lung cancer that is caused exclusively by getting exposed to asbestos.  Doctors typically divide the progression of cancer into four stages primarily based on how far the disease 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 stage, it is generally limited to the pleura.  The two pleura form a surface that surrounds the lung, and are parted 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 stomach ), or the heart.  It may affect the pleura on each side of the body.  It may 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 outside the diaphragm and in the peritoneum ( the membrane that surrounds the abdominal hole ).  It may also affect lymph nodes outside of the chest. 

Stage IV
In the last of the mesothelioma stages, the cancer has gone thru spreading, that is, it has gone through the bloodstream to spread to the organs far away from the chest and abdomen. 

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 could 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 difficulty swallowing, unexpected weight reduction, or barfing blood.swallowing, sudden weight loss, or vomiting blood.
