What are the early symptoms of lung cancer? 6 most common early symptoms of lung cancer

Most patients with early lung cancer do not have obvious symptoms. In this case, it is very easy to be ignored. However, this does not mean that there are no clues to the early symptoms of lung cancer. In addition, the early symptoms of lung cancer are mainly coughing as the most common symptom. The following is a specific 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 the tumor blocks the bronchus, there is often obstructive lung lobe, with varying degrees of severity. Mild cases only have 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 very obvious, but they are not completely fixed. They are generally determined by the different physical conditions of the patients. There are differences between individual patients, but they are not very large. It should be noted that the treatment of advanced lung cancer is very troublesome and basically impossible to cure.
