Lung cancer is a malignant tumor starting point of glandular bronchial epithelium. It is most commonly located in the right lung, in large bronchi and upper lobes. It can be primary or secondary.
Mesothelioma is a malignant tumor originating in the mesothelial cells that make up most of the body foils (special structures, very fine, bounding cavities), including the pleura, peritoneum and pericardium. Malignant mesotheliomas are relatively rare tumors that can be localized to a specific region or may have a diffuse character.
Of these, the most common location is the lung (pleural ie, in 90% of cases). Mesothelioma lung is associated with prolonged exposure to asbestos dust patient.
Carcinogens are everywhere around us, some more hidden in products that few would think of other more exposed, such as those in cigarettes.
Automatically carcinogens do not cause cancer, but favors the development of this serious disease, especially when there is a constant and prolonged exposure to them.
Carcinogenesis is a complex process by which a certain cell in the body suffers a series of mutations caused, in general, exposure to certain environmental factors (chemical, physical and biological).
