What are the diagnostic methods for lung cancer? Introduction to common diagnostic methods for lung cancer

Lung cancer, a bronchial disease, threatens the life safety of patients all the time. Many people are afraid of cancer, especially lung cancer. Conventional examination methods mainly include bronchoscopy, pulmonary function test, chest X-ray, etc. The following is a detailed introduction to the conventional diagnosis methods of lung cancer:

1. Bronchoscopy: It is mainly used to examine patients with unexplained hemoptysis and chronic cough in the diagnosis of lung cancer, as well as the basis for diagnosis and staging of lung cancer patients. Bronchoscopy is used to make slices to obtain tissue diagnosis.

2. Fiberoptic bronchoscopy: It can obtain pathological diagnosis, which is helpful to determine the scope of the lesion and clarify the surgical indicators and methods. This is a very effective method in the nursing diagnosis of lung cancer.

3. Sputum cell examination: In the process of diagnosing lung cancer, the first sputum in the morning should be collected for three consecutive days. Cancer cells can be found in it and lung cancer can be diagnosed. Sputum examination can confirm the diagnosis of some lung cancer patients and determine the histological type of lung cancer. However, it is important to check 4 to 6 times in a row to get a definite result.

4. Pulmonary function test: This lung cancer diagnostic method is mainly used for patients who can undergo surgery. This method can be used to assess whether lung cancer patients can withstand open-chest surgery.

5. Chest CT: It can diagnose early and clearly show the size, shape and cumulative range of lesions in the hilum, lungs and mediastinum, which helps to diagnose whether lung cancer can be removed.

6. 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 fields.

7. Magnetic resonance imaging (MRI): In the diagnosis process of lung cancer, it can determine the scope of lung cancer invasion, stage and the possibility of surgical resection.

8. Scanning examinations of the liver, spleen, bones, brain and other parts: This type of lung cancer diagnosis can determine whether the patient's tumor has metastasized.

9. Chest X-ray: For diagnosing lung cancer tumors. Generally, tumors larger than one centimeter can be found on X-rays.

10. Chest X-ray examination: During the diagnosis of lung cancer, lung shadows are detected through fluoroscopy or frontal and lateral chest X-rays.

11. Positron emission tomography (pET): It helps in diagnosing the nature of tumors in lung cancer patients.
