1. Persistent cough or coughing up blood: A persistent cough may be caused by a lung infection, but a long-standing cough may also be a sign of lung cancer.

2. Difficulty breathing: If you suddenly experience symptoms such as shortness of breath and shortness of breath, it may be because the tumor is compressing the airway.

3. Fever: Unexplained fever may be a manifestation of the body's immune response to cancer cells.

4. Fatigue: Feeling tired for a long time, which cannot be relieved even after adequate rest, may also be related to lung cancer.

5. Symptoms of intracranial metastasis: When lung cancer metastasizes to the head or other parts, it may cause symptoms of intracranial hypertension such as headache, nausea, and vomiting.

6. Symptoms of the cardiovascular system: Lung cancer may cause impaired heart function, such as arrhythmia, palpitations, etc.
