How to diagnose lung cancer? Introduction to several common diagnostic methods for lung cancer

X-ray examination can reveal the location and size of lung cancer, and may reveal local emphysema or atelectasis caused by bronchial obstruction, or infiltrative lesions or pulmonary inflammation adjacent to the lesion.

I believe that many smokers are still afraid of lung cancer, but our experts here remind you that the chance of developing lung cancer from smoking is still quite high. So everyone must try to quit smoking. Below, our experts will introduce several common diagnostic methods for lung cancer:

1. X-ray examination

X-ray examination can reveal the location and size of lung cancer, and may reveal local emphysema or atelectasis caused by bronchial obstruction, or infiltrative lesions or pulmonary inflammation adjacent to the lesion.

2. Bronchoscopy

Bronchoscopes can be used to directly observe the pathological changes in the bronchial lining and lumen. Tumor tissue can be taken for pathological examination, or bronchial secretions can be aspirated for cytological examination to confirm the diagnosis and determine the histological type.

3. Cytological examination

Sputum cytology is a simple and effective method for lung cancer screening and diagnosis. Most patients with primary lung cancer can find detached cancer cells in their sputum. The positive rate of sputum cytology for central lung cancer can reach 70% to 90%, while the positive rate for sputum cytology for peripheral lung cancer is only about 50%.

The three methods mentioned above are the common centralized diagnosis methods for lung cancer. You can refer to them. In fact, if you know more about lung cancer and truly understand the terribleness of this disease, you will definitely have a better body. I also hope that everyone will quit smoking and stay away from the threat of lung cancer.
