Experts introduce the diagnosis and differentiation of small cell lung cancer? Nowadays, environmental pollution is too serious. Severe air pollution and smoke contain carcinogens, which can lead to the occurrence of small cell lung cancer. Today, let's take a look at experts' introduction to the diagnosis and differentiation of small cell lung cancer.

Lung cancer occurs in the bronchial mucosal epithelium and is also called bronchial cancer or primary bronchial lung cancer. In the past 50 years, many countries have reported a significant increase in the incidence of lung cancer, and lung cancer has ranked first among male cancer patients. The cause of lung cancer is still not completely clear, but a lot of data show that long-term and heavy smoking is an important pathogenic factor of lung cancer. Diagnosis and differentiation of small cell lung cancer:

1. Chest CT examination: Lung cancer is diagnosed based on the changes in lung shadow morphology. Clinically, it is usually diagnosed based on the lung window and mediastinum bed, as well as enhanced CT scans. The new generation of spiral CT scans is both time-saving and accurate.

2. Sputum cytology examination: Cancer cells that fall off the surface of lung cancer can be coughed up with sputum. Sputum cytology examination can clearly confirm the diagnosis by finding cancer cells, with an accuracy rate of more than 80%. Especially in cases with bloody sputum, there is a greater chance of finding cancer cells in the sputum, and sputum should be sent for repeated examination several times in a row.

3. X-ray examination: It is one of the most important methods for diagnosing lung cancer. The X-ray manifestation of intermediate lung cancer may show no abnormal signs in the early stage. When the tumor blocks the bronchus, the distal lung tissue becomes infected, and the exhausted lung segment or lobe shows signs of pneumonia. When the bronchial lumen is completely blocked by the tumor, the corresponding lobe or one side of the lung may be deflated.

4. PET/CT examination: It is very helpful for the diagnosis and differentiation of shadows in the lungs. It is even more important for the clinical staging of lung cancer. It can detect metastatic lesions that cannot be found by conventional breast CT and abdominal ultrasound examinations.

5. Thoracotomy: When the nature of the lesion is still unclear after various examinations, and the possibility of lung cancer cannot be ruled out, thoracotomy should be performed if the patient's general condition permits. During the operation, a biopsy or corresponding treatment is performed according to the lesion to avoid delaying the condition.
