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

The cause of lung cancer is related to smoking, so lung cancer is more common in men. Lung cancer can seriously affect a person's respiratory system and can even lead to death. So what are the early symptoms of lung cancer?

1. Cough: Cough is the most common symptom of lung cancer, and about 2/3 of patients have this symptom. It can be a mild dry cough or a severe cough, with varying amounts of sputum. However, in patients with chronic long-term coughs, once the nature of the cough changes, or the frequency of coughing changes or night coughing occurs, be alert to lung cancer. Continuous and uncontrollable coughing is one of the most painful symptoms of lung cancer.

2. Chest pain: Nearly 30% to 40% of patients with early lung cancer experience chest pain, which is generally intermittent and mild chest pain. The symptoms of this type of lung cancer are dull pain or drilling pain, which can last from minutes to hours. If the tumor invades the pleura, the pain will be more severe, continuous and fixed. If chest pain recurs in early lung cancer, the prognosis is poor if the pain recurs later.

3. Hemoptysis: Half of the patients with early lung cancer have this symptom. Once a smoking male over 40 years old has blood, blood streaks or small blood clots in his sputum, the possibility of lung cancer is quite high.

4. Low fever: Cancer cells invade the bronchi, causing bronchial obstruction and pneumonia. In severe cases, there is high fever. The condition may temporarily improve after taking medication, but it will relapse again in a short time.

Now people should know what the early symptoms of lung cancer are. Therefore, when people find that they have the above symptoms, they should go to the hospital for examination immediately. If they have already suffered from lung cancer, they should actively receive treatment so that they have a chance of recovery.
