What are the corresponding early symptoms of lung cancer? There are 5 main symptoms of lung cancer in the early stage

In recent years, the incidence of lung cancer has been gradually increasing, so we must pay enough attention to this disease. In fact, many people don’t know where to start the corresponding lung cancer treatment, because many people don’t know what the early symptoms of lung cancer are.

1. Hoarseness

This is one of the most important early features of lung cancer and is also a new discovery that experts at home and abroad have been exploring in recent years.

Hoarseness can occur in pharyngitis, colds and acute bronchitis; after thyroid surgery, pharyngeal surgery; it can also occur after improper voice, excessive talking, or even after heavy smoking and drinking. However, this type of hoarseness can generally be treated symptomatically or healed by rest. Hoarseness caused by lung cancer, thyroid cancer and laryngeal cancer is completely different from the above types of hoarseness, especially lung cancer.

Other early symptoms of lung cancer, such as cough, chest pain, hemoptysis, etc., lack characteristic features, but hoarseness has certain specificity. According to statistics, about 20% to 30% of lung cancer patients may experience hoarseness at different stages of the disease, including the early stage, of which central lung cancer may be as high as 40%. The pathology of hoarseness caused by lung cancer is that the tumor invades and compresses the nerves that control the vocal cords. This 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 rest and anti-inflammatory symptomatic treatment for more than two weeks are still ineffective.

2. Fever

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

3. No symptoms

About 1/3 of lung cancer patients do not have any obvious early symptoms, and their lesions can only be detected early through regular examinations.

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.

5. Cough

Lung cancer has different symptoms due to its different locations and functional damage. Since tumors mostly grow on large bronchi and are highly irritating, 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. If people with chronic cough find that the nature of their cough is different from usual, they should be alert. Patients of high-risk age should see a doctor as soon as possible when the cough is ineffective after treatment or lasts for a long time. Those with hemoptysis should see a doctor earlier.

For most patients, as long as we can figure this out, the final treatment effect can be guaranteed. Some people don't understand this and don't know why they got lung cancer. How can such treatment have a good effect? ​​I hope this is helpful to everyone.
