Is atelectasis cancer?

Atelectasis is not a cancer disease. Atelectasis refers to respiratory tract disease caused by pulmonary ventilation dysfunction due to pathological reasons. Tuberculosis is a common cause of atelectasis in clinical practice. After pulmonary infection with tuberculosis bacteria, it may cause alveolar collapse or hollow damage to lung interstitial tissue, resulting in reduced gas volume in lung segments or lobe tissues, resulting in atelectasis. Furthermore, lung tumor diseases may also cause atelectasis, such as squamous cell carcinoma, lymphoma, adenocarcinoma, etc. After space-occupying lesions occur in the lungs, lung tissues are subject to pathological compression, resulting in alveolar tissue unable to store and absorb gas normally, which will cause symptoms of atelectasis. Chronic bronchitis, trachea, bronchial stenosis and other airway diseases may induce atelectasis.
