Cancer mesothelioma starts in the layers of tissue that cover each lung. More rarely it starts in the layer of tissue in the abdomen that surrounds the digestive system organs. Whether it is in your chest (pleural mesothelioma) or your abdomen (peritoneal mesothelioma) in its early stages mesothelioma does not have any symptoms. Symptoms of mesothelioma develop, when caused by the cancer growing and pressing on a nerve or another body organ. 60800 people had mesothelioma, and 32000 died of cancer in 2015.
Mesothelioma consists of two main types’ pleural mesothelioma and peritoneal mesothelioma. In the sheets of tissue that cover the lungs Pleural mesothelioma starts. Peritoneal mesothelioma grows in the tissue lining the inside of the stomach (abdomen). Pleural mesothelioma is more common than peritoneal mesothelioma. Cancer stages tell the physician where it is, how big it is and whether it has spread. When diagnosing your cancer the tests and scans you have, give some information about the stage.
The doctor decide the treatment you need by knowing the stage. Mesothelioma in the abdomen (peritoneal mesothelioma) and mesothelioma in the chest (pleural mesothelioma) uses different staging. Until two to five decades (or more) after exposure to asbestos mesothelioma sign signs and symptoms may not appear.
At stage one, Mesothelioma cells are in the pleura around the lung on one side of your chest. Mesothelioma cells are in the inner layer of the pleura (visceral pleura), but only on one side of the chest, at stage two. Mesothelioma has spread to both layers of the pleura on one side of the body, and has enlarged to form a tumor mass on the pleural tissue around the lungs, or has begun to spread into the diaphragm muscle or the lung tissue, during stage three. Mesothelioma at its fourth stage spreads to the chest wall or the covering of the heart (pericardium) but is still potentially removable by surgery, or it has spread to the lymph nodes on the same side of the chest.
Mesothelioma at its 5th stage, cannot be removed by surgery because it has spread to different parts of the chest wall, or has grown through the diaphragm into the peritoneum, or to the pleura on the other side of the body, or to the chest organs, or through to the inner layer of the pericardium.
Survival depends on many various factors. You can get a lot of practical and emotional support for yourself and your family when you have mesothelioma.
In most cases mesothelioma can be prevented by avoiding exposure to asbestos. Before the use of asbestos commercially the disease was rare.
