Common clinical manifestations of small cell lung cancer include cough, blood-streaked sputum, fever, chest pain, shortness of breath, hoarseness, pleural effusion, among others.

1. Cough

Small cell lung cancer can affect the large airways, and patients may experience irritative dry cough, irritative choking cough, high-pitched metallic cough, and other conditions.

2. Blood in Sputum

Small cell lung cancer is highly invasive and has low cell differentiation. In the early stages, it may present with sputum production, which could contain blood streaks or clots. In severe cases, patients may also experience massive hemoptysis.

3. Fever

If tumor tissue undergoes necrosis, it may induce obstructive pneumonia, leading to fever symptoms.

4. Chest pain

The tumor may invade the pleura, causing chest pain, which can sometimes be persistent dull pain.

5. Shortness of breath

If small cell lung cancer causes partial blockage of the airway, the patient may experience symptoms of difficulty breathing.

6. Hoarseness

If the tumor tissue compresses the recurrent laryngeal nerve, the patient may experience hoarseness.

7. Pleural effusion

If the tumor involves the pleura or obstructs pulmonary lymphatic drainage, the patient may develop pleural effusion.
