What are the early symptoms of lung cancer? 4 early symptoms of lung cancer

Any disease will have certain clinical manifestations in the early stages, but the clinical manifestations of some diseases are not so obvious in the early stages. The same is true for lung cancer. However, experts have summarized some early clinical manifestations of lung cancer. The main purpose is to allow patients to detect the disease as early as possible and receive treatment.

1. Cough. Lung cancer grows on bronchial lung tissue, which usually causes respiratory irritation and irritating cough.

2. When a low-fever tumor blocks the bronchus, obstructive pneumonia often occurs with varying degrees. Mild cases have only low fever, while severe cases have high fever. The condition may temporarily improve after taking medication, but will soon relapse.

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 not certain, 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 cancer patients seek medical treatment because of blood in sputum.

Experts have explained so much about the early symptoms of lung cancer, but we are not professionals after all, so it is still difficult for us to detect it ourselves. Our modern society has improved the living standards, and most people now have a physical examination every year, so some diseases can be detected and treated in time.
