What are the main early symptoms of lung cancer? Introduction to 6 early symptoms of lung cancer

The early symptoms of lung cancer are generally not obvious, and even if symptoms occur, they are easily confused with other upper respiratory tract diseases. However, there are a relatively high incidence group of lung cancer, and it is recommended that such people pay attention to physical examinations in their daily lives. 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.

Lung cancer in the late stage is generally incurable. The mental state of patients in this period is generally not good. In fact, this mental state has a great negative impact on the disease. It is recommended to make self-adjustments in time. In addition, it is also recommended that lung cancer patients pay attention to details in their lives.
