Asbestos is harmful when inhaled in large quantities over a short period of time, and may lead to illness, so prompt medical attention is recommended. The danger of asbestos mainly comes from the fibers. Since the fibers in asbestos are relatively small and almost invisible to the naked eye, they are easily released into the air and inhaled into the body. If inhaled in large quantities for a short period of time, it will be attached and deposited in the lungs, which will lead to lung lesions, such as pulmonary fibrosis, pleural damage, etc., and may also cause lung cancer and malignant mesothelioma. If you inhale a large amount of asbestos in a short period of time, you should go to the hospital in time and cooperate with the doctor to take treatment to expel the asbestos from your lungs. In addition, if you have been working with asbestos or other dusts for a long time, you should go to the hospital regularly for chest CT checkups in order to screen for diseases at an early stage.
