How are asbestos-related diseases detected?

Individuals who have been exposed (or suspect they have been exposed) to asbestos fibers on the job, through the environment, or at home via a family contact should inform their doctor of their exposure history, whether or not they experience any symptoms. The symptoms of asbestos-related diseases may not become apparent for many decades after exposure. It is particularly important to check with a doctor if any of the following symptoms develop -Shortness of breath, wheezing, or hoarseness. -A persistent cough that gets worse over time. -Blood in the sputum (fluid) coughed up from the lungs. -Pain or tightening in the chest. -Difficulty swallowing. -Swelling of the neck or face. -Loss of appetite. -Weight loss. -Fatigue or anemia. A thorough physical examination, including a chest x-ray and lung function tests, may be recommended. The chest x–ray is currently the most common tool used to detect asbestos-related diseases. However, it is important to note that chest x-rays cannot detect asbestos fibers in the lungs, but they can help identify any early signs of lung disease resulting from asbestos exposure
