Lung cancer can present symptoms of chest tightness along with dry cough, or it may simply manifest as dry cough alone. Some early-stage lung cancers might only involve dry cough without other symptoms like chest tightness or breathing difficulties. However, for patients with advanced lung cancer, in addition to dry cough, symptoms may include chest tightness and breathing difficulties. Advanced lung cancer can compress the patient's major airways, leading to narrowing of these airways, and thus cause symptoms such as dry cough and chest tightness. In advanced stages, lung cancer may also be accompanied by a significant accumulation of pleural effusion. In such cases, patients might experience chest tightness and breathing difficulties along with dry cough. Therefore, lung cancer can either solely manifest as dry cough or may also be accompanied by symptoms of chest tightness, particularly in advanced stages, where it is relatively common to have chest tightness along with dry cough.
