Most patients with apical lung cancer do not have obvious clinical symptoms, and a few patients may have symptoms of cough. Cough is the most typical clinical symptom of apical lung cancer. Paroxysmal irritating cough with no or little sputum may occur during the disease. As the disease progresses, clinical symptoms such as blood in sputum, dyspnea, hoarseness and so on may also appear. It should be noted that each patient’s condition is different, so the signs of apical lung cancer will also be different. Once you have unexplained cough, blood in sputum and other symptoms, you should go to the hospital as soon as possible and cooperate with doctors to improve chest CT, fiberoptic bronchoscopy and other related examinations to find out the cause of the disease and clarify the condition.
