What are the symptoms of early lung cancer?

Lung cancer has no special symptoms in the early stage. It only has common symptoms of respiratory diseases, such as cough, blood in sputum, low fever, chest pain, shortness of breath, etc., which are easily ignored. Therefore, many lung cancer patients miss the best treatment period because of this factor.

In order to enable everyone to detect early lung cancer in time, experts have proposed the following symptoms of early lung cancer for reference:

1. Cough. Lung tumors grow on bronchial lung tissue, which usually causes respiratory irritation symptoms and irritating coughs.

2. Low fever. When the tumor blocks the bronchus, there is often obstruction of the lung lobe. The degree varies. The mild case has only low fever, while the severe case has high fever. It can be temporarily improved after taking medicine, but it will relapse soon.

3. Chest pain. In the early stage of lung cancer, chest pain is mild, mainly manifested as dull pain, dull pain, and the location is uncertain, and the relationship with breathing is also uncertain. If the pain persists, it means that the cancer may involve the pleura.

4. Blood in sputum. When tumor inflammation 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 tumor patients seek medical treatment because of blood in sputum.
