Persistent cough
After exposure to asbestos-containing walls or buildings, the asbestos fibers we inhale in our bodies travel to the pleura of the lungs, causing inflammation and edema. The inflammation of the pleura increases the likelihood that nearby blood vessels will discharge fluids. Sometimes, the fragile and swollen blood vessels become sore and release fluid into the pleural cavity, causing pleural effusion. Cancer is the primary cause of this effusion, which causes a persistent wheeze that is difficult to stop. Additionally, in severe cases of malignant mesothelioma, the patient begins coughing up blood, which is extremely serious and requires immediate medical attention.
