How to check lung cancer? There are 5 clinical diagnosis methods for lung cancer

I believe that everyone is familiar with lung cancer. As far as we know, many celebrities have also lost their precious lives because of lung cancer and did not receive effective treatment. Therefore, I hope everyone can pay attention to lung cancer. Generally, it can be cured in the early stage, but if it is discovered late, it will bring great difficulty to the later stage of cure. The following will introduce to you how lung cancer patients should be examined?

1. Chest X-ray and radiography can reveal various circular shadows, pneumonia, atelectasis, pleural effusion, etc. Chest X-ray, CT and MRI examinations can help us understand the relationship between the size of the tumor and the lung lobe, segment and bronchi. Bronchial iodized oil contrast can be performed if necessary.

2. Repeated examination of sputum for cancer cells may yield positive results, which are of diagnostic value.

3. Bronchoscopy can directly observe the lesions, and can also take biopsy samples for pathological examination and bronchial secretion smears to check for cancer cells.

4. If the lung puncture is accurately positioned, a smear examination of the puncture material can generally obtain a positive result, which is of diagnostic value.

5. Superficial lymph node puncture or biopsy: When lung cancer has not yet been confirmed or is accompanied by widening of the upper mediastinum, puncture and aspiration of cells or biopsy of palpable lymph nodes on the neck and clavicle, suspicious subcutaneous masses, and suspected cancerous lymph nodes in other parts can be performed to obtain a pathological histological diagnosis.
