What are the symptoms of lung cancer? If you have these 4 symptoms, be careful that it is lung cancer

Everyone is very afraid of cancer. The reason for this fear is that this disease can have serious effects on the human body and may even affect human life. In recent years, the incidence of lung cancer has been increasing. So what are the symptoms of lung cancer? Let's take a look together.

1. Cough. Cough is a very common symptom in our daily life. Little do people know that early symptoms of lung cancer can also include cough. Lung cancer grows on bronchial lung tissue, which usually causes respiratory irritation and irritating cough.

2. Low fever Lung cancer can also cause patients to have symptoms of low fever. When the tumor blocks the bronchus, obstructive pneumonia often exists with varying degrees. 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 Chest pain is also one of the main symptoms of lung cancer. In the early stage of lung cancer, chest pain is mild, mainly manifested as dull pain, dull pain, uncertain location, and uncertain relationship with breathing. If the pain persists, it means that the cancer may involve the pleura.

4. Blood in sputum. The most serious symptom of lung cancer is blood in sputum, which makes patients panic. 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.
