What is the specific diagnosis method for lung cancer

There are 11 diagnostic methods for lung cancer, but not every patient needs to undergo all 12 tests. The tests should be performed based on the patient's actual situation:

1. Chest X-ray examination: It is an important means of diagnosing lung cancer. Lung shadows can be found through fluoroscopy or frontal and lateral chest X-rays.

2. Chest CT: It can detect and clearly display the size, shape and cumulative range of lesions in the hilum, lungs and mediastinum at an early stage, which helps to diagnose whether lung cancer can be removed.

3. Magnetic resonance imaging (MRI): Determine the extent of lung cancer invasion, staging and the possibility of surgical resection.

4. Positron emission tomography (PET): helps to distinguish between benign and malignant tumors.

5. Sputum cell examination: Sputum examination can help some lung cancer patients get a confirmed diagnosis and determine the histological type of lung cancer, but it takes 4 to 6 consecutive examinations to get the results.

6. Fiberoptic bronchoscopy: It can obtain a pathological diagnosis, which is helpful in determining the extent of the lesion and clarifying the surgical indicators and methods.

7. Digital subtraction angiography: It can determine whether there is lymph node metastasis at the hilum of the lung and the extent of tumor invasion of the bronchial wall, and determine whether there are specific lesions in the shadows of the lung field.

8. Percutaneous lung puncture biopsy: It is suitable for patients who cannot obtain positive results through sputum cytology and bronchoscopy, small peripheral masses in the lungs, new peripheral lung lesions, lesions with unclear growth history, multi-nodular lesions in the lungs, patients with incurable tendency, and lesions that do not require resection.

9. Mediastinoscopy: It is helpful for the diagnosis and TNM staging of tumors.

10. Thoracoscopic examination: mainly used to determine the nature of pleural effusion or pleural mass.

11. Serum tumor marker detection: indirectly determine the presence of malignant lesions by detecting specific substances secreted into the blood by the lesions.
