What are the common symptoms of lung cancer? 7 common symptoms of lung cancer

Coughing up blood and bloody sputum: Coughing up blood is also one of the first symptoms of lung cancer, but its diagnostic significance is more serious than coughing. When the tumor erodes the blood vessels, it can cause severe coughing up blood. Bloody sputum often comes from the tumor area and is mixed with a large number of cancer cells. The detection rate of sputum cells and blood is very high.

In recent years, the incidence of lung cancer has increased year by year, and lung cancer has become a common disease in life. Lung cancer brings great harm to patients and seriously affects the patient's health. In life, many people do not know much about lung cancer, which is not conducive to the discovery of the disease. Therefore, everyone should know something about lung cancer so that they can do a good job of prevention or timely discover the disease and treat it. So, what are the common symptoms of lung cancer?

Common symptoms of lung cancer

1. Cough: This is the most common early symptom. When there is secondary lung infection at the distal end of the bronchial wall stenosis, the amount of sputum increases and becomes mucopurulent sputum.

2. Coughing up blood and bloody sputum: Coughing up blood is also one of the first symptoms of lung cancer, but its diagnostic significance is more serious than coughing. When the tumor erodes the blood vessels, it can cause severe coughing up blood. Bloody sputum often comes from the tumor area and is mixed with a large number of cancer cells. The detection rate in bloody sputum is very high.

3. Fever: There are two types of fever caused by lung cancer. One is inflammatory fever caused by bronchial obstruction or bronchial wall compression, and the other is the so-called "cancer fever".

4. Chest pain: When the tumor is located near the pleura, irregular dull pain is likely to occur. When the ribs and spine are invaded, there may also be persistent chest pain and fixed-point tenderness.

5. Chest tightness and shortness of breath: Shortness of breath caused by bronchial stenosis and obstruction is more common in central lung cancer. Late-stage lung cancer causes shortness of breath and even suffocation due to widespread lesions or metastatic lymph nodes compressing the trachea and carina.

6. Weight loss and cachexia: In late-stage patients, loss of appetite caused by infection, pain, etc., and consumption caused by tumor toxins can all cause weight loss and gradually develop into cachexia.

7. Symptoms caused by tumor compression or invasion: The tumor itself or enlarged lymph nodes can compress adjacent organs and produce different symptoms, such as hoarseness caused by compression of the recurrent laryngeal nerve, difficulty in swallowing caused by compression of the esophagus, and congestion, varicose veins and edema of the head, face and anterior chest caused by compression of the superior vena cava.
