What are the examination methods for lung cancer? Three examination methods for lung cancer

Lung cancer makes many patients miserable. They may experience coughing, chest pain, fever, etc., which seriously threatens their lives. Many people are worried that they have lung cancer and want to go to the hospital for examination, but they don’t know what examination items to take. Let’s learn from the experts below:

(a) X-ray negative, sputum negative

1. Asymptomatic patients with three high-risk factors (male, age ≥45 years, and smoking >400 cigarettes/year) should undergo 70-100 mm fluorescent microscopic X-ray or chest fluoroscopy and sputum cytology every six months.

2. Patients with hemoptysis and/or dry cough accompanied by the three major high-risk factors should undergo repeated sputum cytology examinations and receive regular anti-inflammatory treatment; fiberoptic bronchoscopy (bronchoscopy) and video fluoroscopy can be considered. If repeated sputum examinations or microscopic examinations are still negative, they should be reexamined every two months for one year.

(ii) X-ray negative, sputum positive

1. Rule out upper respiratory tract and esophageal cancer.

2. Perform bronchoscopy and try to see the sub-sub-segment. If there is any suspicious local mucosal thickening, roughness or blood stains, brush, wash or puncture the bronchial wall mucosa to look for cancer cells. If the local area is uneven or obviously rough, consider taking a bite biopsy.

3. Perform TV fluoroscopy, change body position, and pay special attention to small nodules in hidden areas.

4. If the above examinations fail to find the lesion, sputum, electrodialysis and bronchoscopy should be repeated every two months. CT examination can also be performed, and sub-layering should be performed in suspicious areas. Regular reexamination should continue for no less than one year.

(III) X-ray positive, sputum negative

1. Patients with segmental or lobar pneumonia or obstructive pneumonia and suspected central lung cancer should undergo bronchoscopy, including transbronchial biopsy (TBB), or selective bronchography; and repeated sputum examination should be performed.

2. Local sectional films should be taken for masses or nodules. Transbronchial lung biopsy (TBLB), percutaneous lung biopsy, or aspiration for cytological diagnosis can be performed if conditions permit.

3. Perform sputum examinations at least twelve times continuously.

4. If repeated sputum tests are still negative but X-rays highly suspect lung cancer, exploratory thoracotomy and frozen section biopsy should be performed.

If you want to confirm whether you have lung cancer, you must do all the above tests. Otherwise, the test results will be inaccurate and the disease cannot be discovered in time. If you have been diagnosed with the disease, you must adjust your mentality and receive treatment. At the same time, you must also strengthen nursing work.
