What are the obvious symptoms of lung cancer in the early stage? These symptoms of lung cancer in the early stage are very common

Early symptoms of lung cancer are generally asymptomatic. About 1/3 of lung cancer patients have no obvious early symptoms, and can only rely on regular examinations to detect the disease early. This is a more troublesome symptom because many patients do not have the habit of regular physical examinations.

Lung cancer is the most common malignant tumor. Experts point out that many people have lost their lives due to this disease. So when you find yourself with this disease, you should be careful. Moreover, this disease will metastasize in the late stage. In the end, the patient can only remove the diseased organs, which has very serious consequences. Therefore, it is very important to detect lung cancer early.

What are the obvious symptoms of lung cancer in the early stages?

Early symptoms of lung cancer are generally asymptomatic. About 1/3 of lung cancer patients have no obvious early symptoms, and can only rely on regular examinations to detect the disease early. This is a more troublesome symptom, because many patients do not have the habit of regular physical examinations. Many people only think of going to the hospital for examination when they have serious symptoms. However, by then, the condition has often begun to deteriorate, and there is generally little hope for cure. Therefore, develop the habit of regular physical examinations and check and diagnose symptoms in a timely manner.

Some of the early symptoms of lung cancer, such as cough, chest pain, hemoptysis, etc., lack characteristic features, while hoarseness has certain specificity. According to statistics, about 20%-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.

Cough. Lung cancer has different early 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. People with chronic coughs should be alert if they find that the nature of their cough is different from usual. Patients of high-risk age should seek medical attention as soon as possible when the cough is ineffective after treatment or lasts for a long time. Those with hemoptysis should seek medical attention early.

In fact, the development of lung cancer is gradual. At the beginning, the patient may have other lung diseases, which lead to lung inflammation. At this time, the environment of the lungs will change, and cancer cells will easily grow in the body. If the patient knows the cause of lung cancer, he can take preventive measures before lung cancer occurs.
