What are the symptoms of lung cancer if the lung nodules are present

Lung nodules may be an early manifestation of lung cancer. Common symptoms include persistent cough, chest pain, dyspnea and coughing up blood. After discovering lung nodules, you should see a doctor as soon as possible for a CT scan, PET-CT or biopsy to confirm the diagnosis.

1. Persistent cough is one of the common symptoms of lung nodules. Especially when the cough lasts for more than two weeks without relief, it may be related to lung cancer. It is recommended to perform chest CT examination in time to rule out malignant lesions.

2. Chest pain is another important symptom of lung nodules. The pain may be concentrated in a certain area of ​​the chest and worsen with breathing or coughing. If chest pain is accompanied by weight loss or fatigue, you should be alert to the possibility of lung cancer and further examination is recommended.

3. Dyspnea may be related to lung nodules compressing the airway or affecting lung function. If you feel short of breath after even a slight activity, you should see a doctor as soon as possible to determine the cause through lung function tests and imaging examinations.

4. Coughing up blood is a dangerous sign of lung nodules, especially when coughing up bright red or dark red blood, which may be related to lung cancer. You need to see a doctor immediately for bronchoscopy and pathological analysis to rule out malignant lesions.

After the discovery of lung nodules, a treatment plan should be developed in combination with imaging examinations and pathological results. Early lung cancer can achieve a better prognosis through surgical resection, radiotherapy or targeted therapy. Regular follow-up and a healthy lifestyle can help reduce the risk of recurrence.
