Quizplus · Accepted Answer

Although the etiology of pulmonary emphysema is not completely understood, long-term cigarette smoking appears to be a contributing factor. Progressive and irreversible changes in the bronchi can result from constant irritation from smoking or exposure to industrial pollution or recurrent infections. There is an increased risk for lung cancer, especially in those with asbestosis.
