What tests should be done for lung cancer? Three tests that must be done for lung cancer

The occurrence of lung cancer is life-threatening. It is very necessary to prevent this disease. After the disease occurs, it is necessary to go to the cause for examination and treatment in time. The preliminary examination is very critical, which is the first step of treatment. So what kind of examination should be done for lung cancer? Experts will introduce it to you. 1. Sputum for cancer cells in lung cancer examination: Sputum for cancer cells is a convenient, fast and non-invasive examination that is easy to promote and apply. Once cancer cells are found in sputum, the diagnosis can be established, so it has diagnostic value. The quality of sputum and the time of submission directly affect the detection rate of cancer cells. It is best to use the first sputum coughed up from the deep lungs after gargling in the morning and check it within 1 hour. Sputum containing blood is better, and purulent sputum should be avoided. Repeated submission can further increase the positive rate. 2. Fiberoptic bronchoscopy: For the diagnosis of near-hilar lesions, fiberoptic bronchoscopy can be combined with fine needle puncture biopsy to further improve the positive rate. 3. Low-dose chest spiral CT examination: Lung cancer examination can detect tiny lesions that cannot be found by conventional chest X-rays. Some foreign studies suggest that screening lung cancer with low-dose spiral CT can significantly improve the detection rate of early lung cancer. After surgical treatment of early lung cancer, most patients can be cured and survive for a long time. Special attention should be paid to ground-glass lesions and small nodular lesions on CT, which may be more significant than previous chest X-rays. New abnormal shadows on chest CT should be further examined or followed up to rule out the possibility of lung cancer. Knowing what examinations to do for lung cancer will help us with treatment after the disease. I hope everyone can learn more about lung cancer in life, which is good for us whether it is to prevent or treat lung cancer. Finally, I wish the patients a speedy recovery!
