What are the methods for early diagnosis of lung cancer? 3 methods can be used to diagnose early lung cancer

Methods for diagnosing early lung cancer include mediastinoscopy, transbronchial lung biopsy, EBUS-TBNA, etc. After diagnosis, doctors usually choose reasonable and effective treatment methods based on the patient's specific pathological type, clinical stage, overall condition, etc. After treatment, the patient's good prognosis depends on early detection, early diagnosis, and early treatment.

Lung cancer is a malignant tumor disease that everyone is familiar with. There are many causes of this disease, and smoking is the most important high-risk factor. Once suffering from the disease, most patients may experience symptoms such as shortness of breath, fever, irritating dry cough, blood in sputum or bloody sputum, chest pain, etc. Patients with these symptoms should be diagnosed as soon as possible. So what are the methods for early symptoms of the disease?

1. Mediastinoscopy

Mediastinoscopy is an effective method for diagnosing the disease and evaluating lymph node staging, and is also the gold standard for clinical evaluation of the status of mediastinal lymph nodes in lung cancer.

2. Transbronchial lung biopsy

Transbronchial lung biopsy can be performed under the guidance of X-ray, CT, virtual bronchoscope, fine bronchoscope, airway ultrasound probe and electronic navigation bronchoscope. This type of biopsy is suitable for diagnosing 2/3 of peripheral lung lesions in China and abroad. While diagnosing ppL, it can also understand the specific situation in the lumen, and is an important means of non-surgical diagnosis of lung nodules.

3. EBUS-TBNA

EBUS-TBNA can puncture the lymph nodes and masses around the trachea or bronchus, which is helpful for the diagnosis of the disease and lymph node staging. At the same time, this examination can perform real-time puncture of intrathoracic lesions, and can obtain more accurate pathological and cytological diagnosis of lung cancer lesions and lymph node metastases, and it is safer and more reliable. In addition, traditional TBNA is based on chest CT positioning operation, which has high requirements for the operator, so it is not used as a routine examination method, but hospitals with conditions should actively carry out it.
