How to diagnose lung cancer early

How to diagnose lung cancer early?

1. The diagnosis of early lung cancer mainly relies on imaging diagnostic methods, such as chest X-ray and CT, which can diagnose some early lung nodules.

2. The diagnosis of early lung cancer mainly relies on imaging diagnostic methods, such as chest X-ray and CT. Abdominal ultrasound is mostly used to diagnose whether there is metastasis to abdominal organs, to show whether there is pleural effusion in the chest, to determine the amount of pleural effusion, and to determine the nature of the disease causing pleural effusion.

Can lung CT detect lung cancer?

For early lesions that are small, patients may not have obvious symptoms such as coughing, sputum, and chest pain. Chest CT may show small lung nodules. At this time, it is necessary to closely review the lung CT to observe changes in lesions to rule out lung cancer. As the lesions grow larger, chest CT will show characteristic manifestations of malignant diseases, such as burrs around the lesions, lobes, and pleural traction, all of which indicate a high possibility of malignancy. Further bronchoscopy or puncture biopsy of the lung lesions to obtain pathology is required for further confirmation. Therefore, lung CT can be used for clinical screening of some lung cancers, and the diagnosis still depends on pathological examination.

Lung CT can detect space-occupying lesions in the lungs, but the diagnosis of lung cancer requires fiberoptic bronchoscopy or puncture biopsy to clarify the pathological nature. Lung cancer can be detected through lung CT examination. Lung cancer mainly appears as a mass in the lungs. CT examination can clearly show the size and shape of the mass, so a preliminary judgment can be made. Of course, a comprehensive examination is required for the final diagnosis. CT alone cannot make a final diagnosis.
