Early symptoms and manifestations of lung cancer

Early symptoms and manifestations of lung cancer are usually mild, and may not even cause any discomfort. Symptomatic patients may experience respiratory symptoms, systemic symptoms, chest pain, chest tightness, hoarseness, etc.

1. Respiratory system symptoms: such as cough, sputum, shortness of breath, dyspnea, etc. These symptoms may be caused by the tumor itself or its secretions, or by bronchial stenosis or obstruction caused by the tumor.

2. Systemic symptoms: such as fever, fatigue, weight loss, etc. These symptoms are usually caused by abnormal body metabolism caused by tumors.

3. Chest pain and tightness: Some patients with early lung cancer may experience chest pain or tightness, which may be caused by tumor invasion of the pleura or chest wall.

4. Hoarseness: If the tumor compresses or invades the recurrent laryngeal nerve, it may cause hoarseness or loss of voice.

Some complications may also occur, such as pleural effusion, pericardial effusion, etc. These symptoms are usually caused by tumor invasion of surrounding tissues or metastasis.

If you experience any related symptoms, please seek medical attention for professional examination in a timely manner.
