Lung cancer can be detected at early stage and patients need to consult doctors for diagnosis through imaging examination, endoscopy and pathology examination.
1. Imaging examination: Usually, patients can understand the location, size and invasiveness of lung cancer to neighboring parts through chest X-ray, and can also verify the scope of lesions through chest CT, and can roughly differentiate its benign and malignant nature, among which low-dose spiral CT can play an important role in the diagnosis of early-stage lung cancer.
2. Endoscopic examination: it can directly observe the lesion, or lesion tissues or cells, so as to carry out biopsy and pathological diagnosis, and the main methods are mediastinoscopy, bronchoscopy and thoracoscopy.
3. Pathological examination: it mainly includes cytological examination and histological examination, in which cytological examination of cells obtained from endoscopy, pleural effusion, sputum, etc. is conducive to preliminary diagnosis. Lung biopsy, on the other hand, is the gold standard for diagnosing lung cancer.
Patients are recommended to have regular medical checkups, and if there is a risk of lung cancer, they also need to actively cooperate with their doctors to undergo relevant examinations, so as to have early detection, early diagnosis and early treatment.
