Assessment of Respiratory Function

A 72-year-old male patient is scheduled for a bronchoscopy, due to changes noted on a recent chest x-ray. A retired factory worker, the patient was recently notified that the buildings that he had worked in for over 25 years were destroyed due to asbestos. Additionally, the number of employees from this company with respiratory diseases or allergies is significantly above the national averages. What symptoms would you anticipate the patient would have presented with to warrant a chest x-ray?
