What are the common symptoms of early lung cancer? 6 clinical manifestations of early lung cancer

In the early stages of lung cancer, lung cancer patients generally do not have any symptoms, so people usually do not pay much attention to it. But it does not mean that there are no symptoms in the early stages of lung cancer. The early symptoms of lung cancer are accompanied by coughing, and may also be accompanied by chest pain and shortness of breath. The following is a detailed introduction to the symptoms of lung cancer:

Early symptoms of lung cancer:

1. Cough: Lung cancer grows on bronchial lung tissue, which usually causes respiratory irritation symptoms and irritating cough.

2. Blood in sputum: When tumor inflammation causes necrosis and capillary damage, there will be a small amount of bleeding, which is often mixed with sputum and appears intermittently or intermittently. Many lung cancer patients seek medical treatment because of blood in sputum.

3. Clubbing: Also known as drumstick finger, it is characterized by hypertrophy of the first segment of the fingers and toes, protrusion and bending of the nails, and is often accompanied by pain. According to foreign reports, 21% of early lung cancer is accompanied by clubbing, and most of them disappear after lung cancer surgery.

4. Polymyositis: It is also one of the early symptoms of lung cancer. According to statistics, 85% of them appear before the typical symptoms of lung cancer, manifested as progressive general weakness and loss of appetite. When it worsens, it may be difficult to walk and difficult to get out of bed.

5. Gynecomastia: A man's breasts may be enlarged on one or both sides like a woman's. Japanese researcher Abei et al. investigated 267 cases of lung cancer, among which 7.5% had gynecomastia in the early stages. Gynecomastia is often ignored or even misdiagnosed as simple breast hyperplasia and removed.

6. Low fever: When a tumor blocks the bronchus, obstructive pneumonia often occurs with varying degrees. Mild cases have only low fever, while severe cases have high fever. The condition may temporarily improve after taking medication, but will soon relapse.

When lung cancer reaches the late stage, the symptoms generally become more and more obvious, but this is not absolute. It still depends on the different physical conditions of the patients, but it should be emphasized that the late stage of lung cancer is already a very serious and dangerous period. The treatment for this period is also very difficult, and the possibility of cure is also very low.
