Malignant mesothelioma

Mesothelioma (cancer of the mesothelium) is a rare form of cancer. Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles. It is known that family members of workers exposed to asbestos can contract this disease through exposure to the worker’s clothing. The combination of smoking and asbestos exposure significantly increases a person's risk of developing cancer of the air passageways in the lung.

This disease is very difficult to assess consistently due to the great variability in time before diagnosis and the rate of progression of malignant mesothelioma. The cancer keep growing until it is treated so it is very important that disease is diagnosed an treated as early as possible Mesothelioma occurs more often in men than in women and risk increase with age, but this disease can appear in either men or women at any age. Most cases of mesothelioma occur 30-45 years after initial exposure to asbestos.

Mesothelioma is a type of cancer that can be malignant or benign, the malignant type is very dangerous type and may be deadly in most cases. Scientists can classify the types of mesothelioma cancer according to the place of the tumors as following.

Pleural type, in this type the tumors will be developed in Pleura. The Pleura is the most outer membrane surrounds the lungs and has protections functions. Pleural type is the most famous type and the most cases are diagnosed as Pleural mesothelioma.

Peritoneal type, in this case the tumors will be developed in the Peritoneum. The Peritoneum is the outer membrane that surrounds the internal organs of the abdomen and has protection and movement functions. It is less common type but it is more dangerous that the Pleural type.

Pericardial type, in this case the tumors will be developed in the Pericardium. The pericardium is the outer sac that includes the heart and its great arteries. Pericardium is a protective systems for our hearts and the mesothelioma cancer in that systems is very deadly.
