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

The early symptoms of lung cancer are not very obvious and can be easily ignored by patients. The most common symptoms are coughing and other upper respiratory tract disease symptoms. As the disease progresses, patients may cough up blood and other reactions. When middle-aged and elderly people experience this, it is important to make a timely diagnosis. Here are some of the symptoms of lung cancer:

1. Blood in sputum: When inflammation of lung cancer tumors causes necrosis and capillary damage, there will be a small amount of bleeding, which is often mixed with sputum and appears intermittently or intermittently. Many lung cancer patients seek medical treatment because of this symptom. Therefore, this is an early symptom of lung cancer.

2. Low fever: When lung cancer tumors block the bronchus, obstructive pneumonia often occurs. The early symptoms of this type of lung cancer vary in severity. Mild cases only have low fever, while severe cases have high fever. The condition may temporarily improve after taking medication, but will soon relapse.

3. Chest pain: The early symptoms of lung cancer may be mild chest pain, which is mainly manifested as dull pain, dull pain, and the location is not certain, and the relationship with breathing is also uncertain. If the pain persists, it means that the cancer may involve the pleura.

4. Cough: Lung cancer grows on bronchial lung tissue, which usually causes respiratory irritation symptoms and irritating cough. Cough is the most common early symptom of lung cancer.

Although lung cancer is very common at present, it has not attracted enough attention from people. Of course, this is also closely related to the characteristics of the causes of lung cancer. But no matter from which aspect, the prevention and early treatment of lung cancer must be faced squarely. This is a major factor of human death in today's life.
