What are the typical symptoms of lung cancer patients? Four common typical symptoms of lung cancer

The harmfulness of lung cancer cannot be ignored. Nowadays, there are many patients with lung cancer, but many people do not understand the symptoms of the disease, so they easily miss the best time for treatment. To treat lung cancer, you should first understand the symptoms of the disease and do not miss the best time for treatment.

1. Fever: There are two types of fever caused by lung cancer. One is the inflammatory fever caused by bronchial obstruction or bronchial wall compression, and the other is the so-called "cancer fever", which is the cancer fever caused by toxins produced by tumor necrosis. It often appears in the later stage after extensive metastasis. This is the symptom of early lung cancer.

2. Chest pain: When the tumor is located near the pleura, it is easy to produce irregular dull pain. When the ribs and spine are invaded, there may also be persistent chest pain and fixed-point tenderness, which is also a symptom of early lung cancer. If the tumor compresses the intercostal nerves, the chest pain is located in the area where the nerves run. If the mediastinal lymph nodes are affected, deep pain behind the sternum may occur, and pain in the pit of the stomach may occur when the tumor is close to the diaphragm. Usually, chest pain occurs earlier in patients with undifferentiated cancer, and later in patients with squamous cell carcinoma. This is due to the early metastasis of mediastinal lymph nodes in undifferentiated cancer;

3. Cough: It is the most common symptom of early lung cancer. The cancer irritates the bronchial mucosa and causes a dry cough with no sputum or a small amount of white foamy mucus sputum. The enlargement of the tumor causes bronchial stenosis, and the cough worsens. It is often persistent and presents a high-pitched metallic sound, which is a characteristic obstructive cough. When there is secondary lung infection at the distal end of the bronchial wall stenosis, the amount of sputum increases and presents thick mucous sputum.

4. Hemoptysis and bloody sputum: Hemoptysis is also one of the symptoms of early lung cancer. Although its incidence is lower than coughing, its diagnostic significance is more serious than coughing. It is characterized by intermittent and repeated small amounts of bloody sputum, often with more blood than sputum, brighter color, and sometimes continuous and difficult to control. When cancer erodes blood vessels, it can cause severe hemoptysis. Bloody sputum often comes from the tumor area, mixed with a large number of cancer cells, and the detection rate of sputum cells and blood is very high.

Although lung cancer is a common disease, many people do not understand the symptoms of the disease, so it is very easy to miss the best time for treatment. In the process of treating lung cancer, patients should first receive treatment in the early stages of the disease to ensure the treatment effect of the disease.
