Mesothelioma is a tumor that is derived from the mesothelial cells of the pleura, peritoneum, pericardium and tunica albuginea. The mesothelium is a membrane that covers all our cavities internally.
The pleural location is the most frequent (80%), affecting the pleura diffusely. The pleura is the membrane that covers the rib cage and the surface of the lungs.
Mesothelioma Information : What Causes Mesothelioma?
It is a rare tumor. It occurs between the 5th and 7th decade of life due to previous occupational exposure to asbestos or asbestos (a mineral) in youth. The incidence is highest in Australia, Belgium and Great Britain (with more than 20 cases per million inhabitants); in Spain, the incidence is less than 22 cases per million, and mesothelioma accounts for 0.3% of cancer deaths. The incidence is higher in men than in women.
The average survival of those affected by malignant mesothelioma is between six and 18 months.
Other Known Casues of Mesothelioma
Other causes of mesothelioma are ionizing radiation (increased incidence in patients previously treated with radiotherapy) or SV40 virus, present in 60-86% of mesothelioma samples (although conclusive results can not be drawn from the studies).
