It may sound like something exotic, but mesothelioma is a form of rare cancer. It occurs at the outer surface of the lungs and is typically associated with exposure to asbestos. Therefore it is often called asbestos lung cancer. There have been a few cases where it was observed in people who had never been exposed to asbestos. It can also be attributed to irradiation and the inhalation of certain fibrous silicates. Mesothelial cells are cells which surround all our organs and it is in these that the Mesothelioma cancer occurs. There are different types types of mesothlial cells: epitheliod, sacromatoid and biphasic. In case of cancer one or more of these may be present in different combinations.
Epitheliod cells are the most common cancer cells of the three. They represent up to 70% of cells in malignant mesothelioma. This type of cell has a cubed shaped appearance and as a group they appear in a tubular and uniform arrangement. biphasic mesothelioma cells are less common, they account for up to 30% of mesothelioma cells and are a combination of the two other kinds. Biphasic cells frequently occur when the other two types of cells are already present in a tumor. The occurrence of sarcomatoid is in general rare. In some instances the mesothelioma can also occur from benign and the non-malignant cells. This is in general rare though. Also this type of mesothelioma cancer can be treated surgically.
The symptoms vary from shortness of breath, cough and chest pain. These happens due to the accumulated fluid in the pleural space of the lungs. Other symptoms include fatigue, anemia, wheezing, or blood in the sputum or coughed-out fluid. If it gets to an extreme case, tumors may be present which may cause the lung to collapse. Or spread the cancer other parts of the body. Signs and symptoms usually appear a long time after the actual exposure, typically twenty to fifty years after exposure to asbestos.
