Mesothelioma Facts



Mesothelioma Facts
Mesothelioma is an odd form of cancer that happens in the mesothelium. The mesothelium is made up of visceral and parietal surfaces which surround organs and body cavities, for example the lungs or abdomen. The abdominal surface straight away surrounds the organ, and the parietal surface is a sac covering the visceral membrane.
There is a lubricating liquid between these surfaces that make up the mesothelium. This liquid helps organs move simply between surrounding structures. In the case of the lung, it helps reduce friction between the lung and chest wall during ordinary respiring as the lung expands.
Here are more mesothelioma facts:
There are different sorts of mesotheliomaIn the abdomen, it is called peritoneal mesothelioma ; on the lungs, it is called pleural mesothelioma ; and if it develops on the heart, pericardial mesothelioma.
It develops mostly on the lungs:
The most typical location for mesothelioma to develop is on the lungs. About two-thirds of all mesothelioma cases develop in the pleural mesothelium. This mesothelioma on the lungs is named malevolent pleural mesothelioma (MPM). The remaining cases develop in the peritoneal mesothelium in the abdomen. A cancer in the intestinal mesothelium is called peritoneal mesothelioma. Seldom , mesothelioma occurs in other mesothelial tissue, for example on the heart or on the reproductive organs.
It might have other causes:

Although asbestos is the major cause of mesothelioma, up to 30-50% of all cases are not obviously related to previous asbestos exposure. Other possible reasons include previous exposure to radiation or to particular minerals closely related to asbestos that are found in the soil. Smoking has not been shown to be a cause of mesothelioma. However, if a smoker has also been exposed to asbestos, this seriously increases their possibility of developing other types of lung cancer.
It has a long development time:
It has a long latency period, which means that symptoms don’t develop for 20-50 years after environmental exposure. The average age at which symptoms customarily begin to appear is around 60 years old.
It occurs more in men than in women:
Mesothelioma affects men about 3 times more often than girls in America. Occurrence rises continuously with age. In other parts of the planet, where exposure comes primarily from other environmental sources, for example in Turkey, mesothelioma occurs about similarly in men and women.
It is a rare disease:
An estimated three thousand to four thousand cases of mesothelioma are diagnosed yearly in the USA. In other nations, the quantity of cases varies. Overall, the number of cases reported each year seems to be increasing.
Mesothelioma Cure:
Doctors and analysts are looking and working difficult to find solutions relating to a cure for mesothelioma but have not discovered any yet.
