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

If a person feels uncomfortable in the throat, hoarseness, and always coughs, then he may have lung cancer. At the same time, the incidence of lung cancer has been increasing in recent years, and lung cancer is a disease that can directly affect people's life safety. So what are the early symptoms of lung cancer?

Early symptoms of lung cancer:

1. Cough: Lung cancer tumors grow mostly on large bronchi, which are highly irritating, so coughing is easy to occur. However, the degree of cough varies. About 50% of patients have irritating coughs, no sputum or a little white foamy sputum. After secondary infection, the quality of sputum also changes. People with chronic coughs should be alert if they find that the nature of their cough is different from usual.

2. Hoarseness: Hoarseness caused by lung cancer, thyroid cancer and laryngeal cancer is completely different from hoarseness caused by colds, smoking and drinking, especially lung cancer. The pathology of hoarseness caused by lung cancer is that the tumor invades and compresses the nerves that control the vocal cords. This kind of hoarseness often occurs suddenly, progresses rapidly, and even completely loses the voice. At the same time, most patients are accompanied by chest pain, etc., and there is no improvement after rest and anti-inflammatory symptomatic treatment for more than two weeks.

3. Fever: When central lung cancer grows in the bronchus and develops to the point of semi-obstruction or complete obstruction of the bronchial lumen, obstructive pneumonia may occur. The fever is generally around 38°C and can be easily reduced by anti-inflammatory treatment. However, if the obstructive lesions are not removed, pneumonia will reappear soon, forming recurrent pneumonia.

4. Coughing up blood: This is special in early lung cancer cases. For example, in central lung cancer, coughing up blood often occurs in the early and middle stages of the disease. The amount of blood is not much, and the blood is bright red or mixed with foam. The reason for this phenomenon is that the surface of the tumor is rich in blood vessels. Coughing damages the surface layer, causing blood vessels to rupture. If there is occasional coughing up blood, it often recurs or only lasts for a long period of time.

Therefore, smoking is harmful to human health, and you should live in an area with good air quality so that your lungs are not easily damaged. At the same time, your chance of developing lung cancer will be lower. At the same time, all lung cancer patients should face the disease calmly and strive to recover as soon as possible.
