What are the early symptoms of lung cancer? There are six symptoms of early lung cancer

In the early stages of lung cancer, the patient's symptoms are generally not obvious. As the cancer continues to develop, the patient will have certain respiratory symptoms, such as common coughing, which are very easy to be ignored. It is recommended that people with a high risk of lung cancer undergo regular physical examinations. The following are 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 night coughing occurs.

2. Chest tightness and shortness of breath are also common early symptoms of lung cancer in women. 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 in women. 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 female 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: Lung auscultation, localized wheezing, whistling, snoring, 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, as long as you pay close attention to the changes in your body, it is not difficult to find.
