Lung cancer may present with a tickling cough in the throat at the beginning. Early lung cancer symptoms are usually not obvious, and there may be an irritating cough with a tickling throat. If the tumor in the central airway causes narrowing of the airway, the cough will be persistent with a high-pitched metallic sound.
The cough of lung cancer patients usually manifests as paroxysmal irritating dry cough. The cough of patients with lung cancer is more serious. Coughing and coughing with pus sputum are not easy to cough up, and patients may feel the presence of itching at the throat.
The occurrence of cough in patients may be related to obstructive pneumonia, changes in bronchial mucus secretion, pulmonary atelectasis and other intrapulmonary comorbidities. In the case of patients with pre-existing chronic bronchitis, there is an increase in the amount of sputum or coughing up purulent sputum. It may also be accompanied by a dry cough, bloody sputum, or an aggravation of the original respiratory symptoms, so be alert to the possibility of a lung infection.
If patients continue to have itchy throat and cough, it may not necessarily be lung cancer, and they need to go to the hospital for further examination to clarify the cause of the disease and carry out corresponding treatment.
