Lung nodules generally need to be examined by chest CT, blood routine, lung cancer tumor markers and other tests first, and then relevant tests will be selected according to the specific lung nodule condition and the next step of treatment.
1. Lung nodules usually need chest CT, blood routine, lung cancer tumor markers and other tests first.
(1) Chest CT can initially observe the number of lung nodules, size, density, whether there are lobes, burrs, pleural depression signs and vascular clusters, and other imaging features and mediastinal lymph nodes, so as to preliminarily determine the benign or malignant possibility of lung nodules.
(2) Blood routine can observe whether there is anemia, white blood cells and platelets and other hematopoietic conditions of the blood system.
(3) Lung cancer tumor marker test, if it is doubly elevated, suggests that the lung nodule may be highly malignant.
2. Relevant tests should be selected according to the specific lung nodule condition and the next step of treatment:
(1) Benign lung nodules: according to the possible causes, such as infection, tuberculosis, immunity, etc., choose infectious index test, tuberculosis-related index test or immunity 12 tests, respectively.
(2) malignant lung nodules: ① with surgical indications: preoperative tests, such as electrocardiogram, lung function, cardiac ultrasound, liver and kidney function, coagulation, head and upper abdomen CT, etc., to rule out contraindications to surgery. ② no surgery when the indications: bronchoscopy or lung puncture biopsy, pleural fluid exfoliated cells (with pleural effusion), in order to the next step of radiotherapy and targeted, biological, immune and other integrated treatment.
Lung nodules to do what examination is recommended to the hospital for further consultation.
