The clinical presentation of lung cancer depends on tumor location: central tumors near major bronchi typically present with cough, hemoptysis, bronchial obstruction causing lobar collapse, a monophonic wheeze (reflecting a single site of airway narrowing, distinguishing it from the polyphonic wheeze of asthma), and secondary infection from impaired airway clearance, whereas peripheral tumors are often asymptomatic and detected incidentally on imaging.
