Cough is one of the manifestations of lung cancer, but it cannot be used to diagnose lung cancer. Cough symptoms can also occur in other diseases such as inflammation of the lungs and allergic diseases.
Cough is a subjective symptom, and there are more causes of cough, such as infectious factors (upper respiratory tract diseases, tracheobronchial diseases, lung, pleural diseases, etc.), physical factors (such as respiratory tract obstruction, bronchial foreign bodies, etc.), chemical factors, allergic factors, etc.
The most common early symptom of lung cancer is mostly cough, often paroxysmal and irritating choking cough with no or little sputum. With the growth of tumor, some tumors will break and bleed, and patients will have blood in sputum, and some patients may also have chest pain, fever and other symptoms. The diagnosis of lung cancer needs to be judged by combining clinical manifestations, chest CT and pathology. Lung cancer cannot be diagnosed solely on the basis of significant relief of coughing symptoms.
For high-risk groups (long-term smokers, family history of tumors, etc.), if this situation occurs, they should be actively investigated for lung cancer, and it is recommended to undergo low-dose spiral ct screening. To avoid ignoring lung cancer, thus missing the best time for treatment.
Therefore, it is not possible to determine whether lung cancer is present based on coughing symptoms alone, and one should go to the hospital to complete the relevant examinations, identify the cause, and give targeted treatment or therapy.
