What are the common symptoms of lung cancer? The symptoms of lung cancer are usually as follows

Compared with most other malignant tumors, the early symptoms of lung cancer are relatively obvious, but they are also very easy to be ignored. Most lung cancer patients are already in the middle and late stages when they are discovered. Generally speaking, the first symptom of lung cancer is coughing. The following is an introduction to the early symptoms of lung cancer:

1. Cough: It is the most common early symptom of lung cancer, and about 2/3 of patients have this symptom. It can be manifested as a mild dry cough or a severe cough, with a high frequency of coughing or coughing at night. However, in patients with chronic long-term cough, once the nature of the cough changes, or the frequency of coughing changes or coughing occurs at night, it is necessary to be alert to the possibility of lung cancer.

2. Chest tightness and shortness of breath are also common early symptoms of lung cancer. In addition to tumors blocking the bronchus and causing atelectasis or lung inflammation causing chest tightness and shortness of breath, the symptoms of late-stage lung cancer are more obvious, and are more serious when pleural effusion occurs in lung cancer.

3. Chest pain: About 30% of lung cancer patients may experience chest pain. If the tumor is located near the pleura, it will produce irregular dull pain or pain, which will be aggravated by breathing or coughing. If the tumor invades the pleura, it will cause continuous and severe pain.

4. Fever: Low fever is also one of the early symptoms of lung cancer. Most of the fever caused by lung cancer is cancer fever caused by inflammation due to tumor blocking the lung bronchi and poor drainage. Antibiotic treatment has poor effect and is prone to recurrence. The body temperature is generally below 38 degrees Celsius.

5. Hemoptysis: It is more obvious in smokers, often manifested as blood in sputum or intermittent bloody sputum. Some patients will also have repeated inflammatory changes in a certain part of the lungs.

6. Early symptoms of lung cancer include localized wheezing, whistling, and snoring when listening to the lungs, which do not change due to coughing. The early symptoms of lung cancer are very hidden, which requires us to observe carefully in life. In fact, there are many early symptoms of lung cancer, and it is not difficult to find them as long as we pay close attention to the changes in our body.

Lung cancer patients may experience respiratory symptoms in the early stages. Of course, the best way to detect malignant tumors is to have regular physical examinations, especially for people with a high incidence of malignant tumors. The same is true for lung cancer. It is generally recommended that people with a high incidence have regular physical examinations starting at the age of 40.
