Correctly diagnose whether there is small cell lung cancer

How to correctly diagnose whether there is small cell lung cancer? Lungs are important respiratory organs of the human body, and small cell lung cancer will have many impacts on our health, and even take the patient's life in severe cases. Today we will take a look at how to correctly diagnose whether there is small cell lung cancer?

1. Bronchoscopy

Bronchoscopy is an important diagnostic method for lung cancer. Through bronchoscope, the pathological changes of the bronchial lining and lumen can be directly observed. If cancer or cancerous infiltration is observed, tissue can be taken for pathological section examination, or bronchial secretions can be aspirated for cytological examination to confirm the diagnosis and determine the histological type.

2. Radionuclide examination

Radioactive drugs such as 67Ga-citrate have affinity for lung cancer and its metastatic lesions. After intravenous injection, they can be concentrated in the tumor and can be used for the diagnosis of lung cancer to show the extent of the cancer. The positive rate can reach about 90 percent.

3. X-ray examination

X-ray examination is the most commonly used method for diagnosing lung cancer. X-ray examination can be used to understand the location and size of lung cancer. Although X-ray examination of early lung cancer cases cannot yet show a mass, it may show local emphysema and atelectasis caused by bronchial obstruction, or infiltrative lesions or pulmonary inflammation in the vicinity of the lesion.

Magnetic resonance imaging (MRI): It is not as good as CT in detecting small lung lesions, but it can more clearly show the relationship between the tumor and large blood vessels. When determining whether there is intracranial metastasis, enhanced MRI is the first choice. Positron emission tomography (PET): Whole-body PET is significantly more accurate than CT and radionuclide bone scanning in determining lung masses, lymph nodes or distant metastases. Sputum cytology: The positive rate is related to the location and size of the tumor, the quality of the sputum, and whether there is concurrent infection. The detection rate of central lung cancer is high, but it is difficult to determine the type, and it is currently not recommended.
