What tests are needed to diagnose lung cancer? Three diagnostic tests for lung cancer

What tests are needed to diagnose lung cancer? In today's society, we have more and more food to choose from, so we should pay attention to the nutritional balance in our diet and good living habits, so that we can improve our physical fitness. If we have lung cancer, we will have the resistance to fight the disease. But what tests are needed to diagnose lung cancer?

1. Lung cancer examination: Finding cancer cells in sputum: Finding cancer cells in sputum is a convenient, fast, 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. Lung cancer examination is particularly suitable for early diagnosis of lung cancer in the central part of the lung. 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 test it within 1 hour. Sputum containing blood is better, and purulent sputum should be avoided. Repeated submission can increase the positive rate.

2. Fiberoptic bronchoscopy: Lung cancer examination is particularly suitable for sputum positive for cancer cells, while chest CT is negative. In addition, the diagnosis rate of lesions near the hilum of the lung is relatively high. Fiberoptic bronchoscopy can be combined with fine needle puncture, X-ray-guided lung biopsy, etc. to further improve the positive rate.

3. Low-dose spiral CT examination of the chest: Lung cancer examination can detect tiny lesions that cannot be found by conventional chest X-rays. Some foreign studies suggest that the use of low-dose spiral CT to screen lung cancer can significantly improve the detection rate of early lung cancer. After surgical treatment of 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. Newly appeared abnormal shadows on chest CT should be further examined or followed up to rule out the possibility of lung cancer.

After reading the above introduction, you should have a better understanding of the question "What tests are needed to diagnose lung cancer?" Lung cancer patients should pay attention to their diet in life. A good diet can make the patient's nutrition balanced. In addition, patients should maintain a relaxed mentality so that the disease can leave our body.
