What are the main early symptoms of lung cancer? If there are 6 symptoms, be careful of lung cancer

Patients with early lung cancer generally have no symptoms, or the early symptoms of lung cancer are not obvious and are easily ignored. However, this does not mean that there are no early symptoms of lung cancer. Generally speaking, the early symptoms of lung cancer are mainly manifested in the form of cough, which may also be accompanied by chest pain and shortness of breath. The following is a detailed introduction to the early 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. Male gynecomastia: One or both sides of a man's breasts become larger than a woman's. Japanese researcher Abei et al. investigated 267 cases of lung cancer, among which 7.5% had early gynecomastia. This condition 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.

The symptoms of advanced lung cancer are not completely fixed. Generally speaking, they are mainly determined by the different physical conditions of the patients. There are differences, but they are not very large. One thing that needs to be pointed out is that the treatment of advanced lung cancer is very troublesome. Generally, symptomatic treatment is the main treatment, but the purpose of treatment is nothing more than to prolong the patient's life and improve the quality of life.
