What tests are needed for lung cancer? Hospitals often use 3 methods to diagnose lung cancer

Bad habits can easily lead to diseases, such as smoking, which is related to lung cancer. If you feel discomfort in your lungs and suspect it is lung cancer, then we need to know what tests are needed for lung cancer.

First, X-ray examination method. As a common clinical detection method, X-ray examination can observe the location and area of ​​lung cancer lesions in patients. For early lung cancer, there may not be obvious tumors yet, so X-rays cannot be seen in this case. However, emphysema caused by bronchial obstruction and lesions near the lesions can be seen through X-rays.

Second, bronchoscopy. Bronchoscopy is also a major means of detecting lung cancer. Through the probe on the bronchoscope, doctors can visually observe the bronchial cavity. If a tumor is found, the diseased tissue can be extracted as a sample for pathologists to slice and test, or bronchial secretions can be extracted for cell examination to make a more accurate judgment.

Third, CT examination is a non-invasive detection method. It has a high application value in the diagnosis of lung cancer. CT can make a relatively accurate positioning of the tumor location and the scope of influence. It can also make a general judgment on the benign and malignant nature of the tumor. In the past, medicine regarded calcification as a characteristic of benign tumors, but now it is found that malignant tumors also have a calcification rate of about 10%. CT can also accurately stage lung cancer, which can be said to be an effective means of lung cancer examination.

Lung cancer can be diagnosed through X-ray, bronchoscopy, CT and other examination measures. The diagnosis rate is generally very high. If you are diagnosed with the disease, you must cooperate with the doctor's treatment seriously. At the same time, you can also consult a doctor if you have any questions. After all, this disease is a serious disease and cannot be treated carelessly.
