cancer that begins in the layers of tissue that cover each lung is known as mesothelioma. More rarely it starts in the layer of tissue in the abdomen that surrounds the digestive system organs. Mesothelioma in its early stages does not have many symptoms, whether it is in your chest (pleural mesothelioma) or your abdomen (peritoneal mesothelioma). Often caused by the cancer growing and pressing on a nerve or another body organ, when mesothelioma symptoms do develop. 60800 people had mesothelioma, and 32000 died of cancer in 2015.
Pleural mesothelioma and peritoneal mesothelioma are the two main types of mesothelioma. The lungs, in the sheets of tissue covering it, pleural mesothelioma starts. In the tissue lining the inside of the stomach (abdomen), grows peritoneal mesothelioma.Peritoneal mesothelioma is less common than pleural mesothelioma. The stage of cancer tells the physician where it is, how big it is and whether it has spread. The tests and scans you have when diagnosing your cancer give some information about the stage.
The doctor decide the treatment you need by knowing the stage. The staging for mesothelioma in the abdomen (peritoneal mesothelioma) is different to staging used for mesothelioma in the chest (pleural mesothelioma). Until two to five decades (or more) after exposure to asbestos mesothelioma sign signs and symptoms may not appear.
Mesothelioma cells are in the pleura around the lung on one side of your chest, at stage one. Mesothelioma cells are in the inner layer of the pleura (visceral pleura), but only on one side of the chest, at stage two. Mesothelioma at stage three, 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 started to spread into the diaphragm muscle or the lung tissue.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.
In the 5th stage, mesothelioma 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 is determined by many different factors.You and your family can get a lot of practical and emotional support when you have mesothelioma.
avoiding exposure to asbestos mesothelioma can be prevented. Before the use of asbestos commercially the disease was rare.
