What are the methods for checking lung cancer

Lung cancer is very harmful to our body, so we must be very careful in treating lung cancer. So what are the methods to check lung cancer? This is a question that everyone is more concerned about. In order to help everyone solve the problem of what are the methods to check lung cancer, let our experts explain it to everyone.

Methods for checking lung cancer 1. Tumor markers Commonly used tumor markers for lung cancer include carcinoembryonic antigen (CEA), β2 microglobulin, ferritin (FER), neuron-specific enolase (NSE), etc. Among them, the positive rate of carcinoembryonic antigen in lung cancer patients can reach 40-60, and its level has a certain relationship with the severity of the disease and the prognosis.

Method 2 for checking lung cancer: Imaging examinations include X-ray fluoroscopy and photographs, tomography, CT, MRI, etc. Main observations: characteristics of lung masses, tumor range, whether it invades the hilum, pleura, chest wall, mediastinum, whether it is accompanied by atelectasis, localized emphysema, obstructive pneumonia, pleural effusion, etc. Fluoroscopy is generally only used as a screening for lung cancer. X-ray diagnosis is the preferred basic method for lung cancer. Frontal and lateral chest radiographs can comprehensively observe the location and morphology of lesions, especially for peripheral lung cancer. CT is an indispensable examination method in the imaging diagnosis of lung cancer. It is of great significance for tumor staging, positioning, understanding the location and range of tumor invasion, and searching for lesions in hidden parts.

Method 3 for checking lung cancer: Pathological cytology examination includes sputum exfoliative cytology, fiberoptic bronchoscopy and percutaneous lung puncture. Among them, sputum exfoliative cytology is the simplest, most economical and effective method for obtaining a pathological diagnosis, with a positive rate of 60% to 80%. It is generally believed that the positive rate of sputum examination for central lung cancer is higher than that for peripheral lung cancer. The cytological diagnosis of small cell lung cancer has the highest consistency with histopathological diagnosis, followed by squamous cell carcinoma, and adenocarcinoma has the lowest. It is appropriate to send sputum for examination 4 to 6 times. Fiberoptic bronchoscopy is an effective means of diagnosing lung cancer. It can directly observe the location and range of the tumor, improve the positive rate of cytological and histological examinations, and perform local treatment.
