Lung cancer is the most common cancer in our lives, and it has a huge impact on our lives. One of the main symptoms is pain. For lung cancer patients, the pain of lung cancer is unbearable, so it is most important for lung cancer patients to know how to relieve the pain of lung cancer.

1. Positron emission tomography

Mainly, chest CT cannot clearly diagnose lung nodules and enlarged diaphragmatic lymph nodes. Generally, the advantage of positron emission tomography is that it can clearly diagnose the symptoms of lung cancer.

2. Sputum cytology is a lung cancer screening

Sputum cytology is the most effective and convenient method for lung cancer screening and diagnosis. Generally, rinse your mouth with water after getting up, and cough up fresh sputum from the lungs or aspirate bronchial secretions from a bronchoscope as a specimen for examination. Generally, the positive rate can be increased by examination. If the sputum cells of central lung cancer appear at 70% to 90%, it indicates that lung cancer cells have appeared, and the tumor of lung cancer cells will grow, which is not easy to judge. Only through sputum cell examination can lung cancer be diagnosed.

3. Bronchoscope can directly observe the pathological changes of bronchial endothelium and lumen

Bronchoscopy can be used to directly observe the pathological changes in the bronchial lining and lumen, which is also a method for diagnosing lung cancer. Generally, by observing cancer cells and cancerous infiltration, tissue can be taken for pathological section examination, which can also clearly diagnose and determine the tissue type. However, resection surgery can be used for examination, which can correctly diagnose the symptoms of lung cancer.

4. Biopsy of metastatic lesions in advanced lung cancer cases

There are superficial lymph nodes in the clavicle, neck and armpits. There may also be subcutaneous metastatic nodules. The tissue can be removed for examination, which is also very helpful in examining the symptoms of lung cancer.
