Asbestos can cause lung cancer that is identical to lung cancer from other causes. Exposure to asbestos is associated with all major histological types of lung carcinoma (adenocarcinoma, squamous cell carcinoma, large-cell carcinoma and small-cell carcinoma). The latency period between exposure and development of lung cancer is 20 to 30 years.
Asbestosis is the scarring of lung tissue (beginning around terminal bronchioles and alveolar ducts and extending into the alveolar walls) resulting from the inhalation of asbestos fibers. There are two types of fibers: amphibole (thin and straight) and serpentine (curly).
Figure B shows lungs with asbestos-related diseases, including pleural plaque, lung cancer, asbestosis, plaque on the diaphragm, and mesothelioma. Left-sided mesothelioma (seen on the right of the picture): chest CT. All types of asbestos fibers are known to cause serious health hazards in humans.
People who lived and worked in Libby breathed in the microscopic needle-shaped asbestos fibers that can cause lung scarring and the lung cancer mesothelioma, the lawsuit argues.
A technique called pleurodesis can be used to intentionally create scar tissue within the pleural space, usually as a treatment for repeated episodes of a punctured lung, known as a pneumothorax, or for pleural effusions caused by cancer. While this procedure usually generates only limited scar tissue, in rare cases a fibrothorax can develop. [6]
Mesothelioma that affects the pleura can cause these signs and symptoms: [15] Chest wall pain; Pleural effusion, or fluid surrounding the lung; Shortness of breath – which could be due to a collapsed lung or the pleural effusion; Fatigue or anemia; Wheezing, hoarseness, or a cough; Blood in the sputum (fluid) coughed up
