What are the clinical symptoms of early lung cancer? 4 early symptoms of lung cancer Early detection and early treatment

Lung cancer is a disease that is more common in men. In fact, it is closely related to men's long-term smoking in life. It is also a disease with symptoms. It is recommended to know more about the symptoms in life. The following mainly introduces what symptoms will appear in the early clinical stage of lung cancer?

1. Cough: In the early stage of lung cancer, there will be some symptoms that are not too typical, including 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 changes or the cough appears at night, be alert to lung cancer. Continuous and uncontrollable cough is one of the most painful symptoms of lung cancer.

2. Chest pain: Nearly 30% to 40% of patients experience pulmonary chest pain in the early stages of lung cancer, 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 the early stages of lung cancer, the prognosis is poor if the pain recurs later.

3. Hemoptysis: In the early stage of lung cancer, about half of the patients will have this symptom in the clinic. If a smoking man over 40 years old has blood in his sputum, blood streaks or small blood clots, the possibility of lung cancer is quite high. This is also a common symptom of lung cancer.

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

In short, if a man feels that he has a series of symptoms such as coughing, chest pain, hemoptysis, low fever, etc. in his life, he must pay attention and take it seriously. At this time, he may have lung cancer. What he needs to do is to go to a regular hospital for examination in time.
