What are the early symptoms of lung cancer?

Lung cancer is a very common malignant tumor in the respiratory system. Early symptoms may mainly be pneumonia-like, such as coughing, expectoration, and a small amount of blood in the sputum. The cough may be a persistent, irritating dry cough. Lung cancer is the most common primary lung malignant tumor, and its incidence is relatively hidden.

The following are specific descriptions of the early symptoms of lung cancer:

1. Cough - Cough is a typical symptom of lung cancer, and its early stage is very similar to a cold. Lung cancer grows on bronchial lung tissue and usually causes respiratory irritation symptoms and irritating cough.

2. Sputum and blood - coughing is usually accompanied by varying degrees of sputum. Even blood may be present in the sputum. Tumor inflammation leads to necrosis, and capillary damage will cause a small amount of bleeding, which is usually mixed with sputum and appears intermittently or intermittently. Many lung cancer patients are treated for sputum and blood.

3. Fever - Long-term persistent low-grade fever is one of the early symptoms of lung cancer. After the tumor blocks the bronchus, there is often obstruction of the lung lobe to varying degrees. Mild cases only have low-grade fever, and severe cases only have high-grade fever. It can temporarily improve after taking medicine, but it will relapse soon.

4. Chest pain - Chest pain is a very common clinical manifestation, usually occurring in patients with early-stage lung cancer. Early chest pain in lung cancer is mild, mainly manifested as dull pain, dull pain, uncertain location, and uncertain relationship with breathing. If swelling and pain continue to occur, it means that the cancer may involve the pleura.

5. Shoulder pain - Lung cancer lesions often affect patients' shoulder pain and back pain. Peripheral lung cancer often develops backward, eroding the pleura, involving the ribs and chest wall tissue, causing shoulder pain and back pain. These patients rarely have respiratory symptoms.

6. Hoarseness is often accompanied by coughing symptoms, which is also one of the common early symptoms of lung cancer. Lung cancer metastasis compresses the laryngeal nerve, which can paralyze the vocal cord and cause hoarseness. Since lung cancer metastasis can appear in the early stage, and the county metastasis can sometimes grow faster than the primary lesion, the clinical manifestation of the metastasis can be earlier than the primary lesion.
