With mesothelioma, causes and risk factors are closely intertwined. Indeed, asbestos is recognized as the major cause of mesothelioma. And therefore, occupational exposure to asbestos is a risk factor; indeed, even minor exposures have been reported as triggers for mesothelioma.
Mesothelioma occurs 15 to 40 years after exposure to asbestos, which explains why its incidence increases after age 50.
What is malignant mesothelioma?
Malignant mesothelioma is form of mesothelioma that is cancerous. There are benign tumors of the mesothelium as well as fibrous tumors of the pleura, which are also benign but can develop symptoms resembling those of malignant mesothelioma. We can also speak of multi-cystic mesothelioma when several benign cysts affect the peritoneum. Finally, there are adenomatoid mesotheliomas: benign tumors that develop in the mesothelium of the reproductive organs.
