What are the common symptoms of lung cancer? Found 4 symptoms that indicate you have lung cancer

Lung cancer is a disease of the lungs. As we all know about cancer diseases, there is no effective treatment for this type of disease. Early detection and early treatment are effective means of treatment. Many people in life do not understand the symptoms of lung cancer, which often delays diagnosis and treatment. In order to prevent and treat this disease in time, let's take a look at the common symptoms of lung cancer.

1. Cough: It is the most common symptom of early lung cancer. The tumor stimulates the bronchial mucosa and causes a dry cough. As the tumor grows, it causes bronchial stenosis, the cough becomes more severe, and it persists. When there is a secondary lung infection at the distal end of the bronchial wall stenosis, thick sputum will appear.

2. Coughing up blood and bloody sputum: Coughing up blood is also a common symptom of lung cancer. Although its incidence is lower than coughing, the condition is more serious than coughing. It is characterized by intermittent and repeated appearance of small amounts of bloody sputum, which is sometimes difficult to control. When the cancer erodes the blood vessels, it can cause severe coughing up blood.

3. Chest pain: When the tumor invades the vicinity of the pleura, lung cancer patients will experience persistent chest pain symptoms. When the ribs and spine are invaded, there may also be persistent chest pain and local tenderness. Chest pain usually occurs earlier in patients with undifferentiated cancer. This is due to mediastinal lymph node metastasis in the early stages of undifferentiated cancer.

4. Chest tightness: Bronchial stenosis and obstruction cause shortness of breath. Diffuse bronchiolar-alveolar cell carcinoma reduces the respiratory area and affects the diffusion function, causing shortness of breath and chest tightness. Advanced lung cancer causes shortness of breath and even suffocation due to widespread lesions or metastatic lymph nodes compressing the trachea and carina.

The above introduces the common symptoms of lung cancer. Although the early symptoms of lung cancer are not very obvious, you can still detect the disease by paying close attention to your physical condition. I would like to remind everyone to pay attention to your physical condition. If you find that you are unsure of your condition, you must go to the hospital for diagnosis and examination to avoid delaying treatment.
