What are the eight key points in diagnosing lung cancer?

In recent years, the incidence of lung cancer has gradually increased. Although modern technology is advanced, the symptoms of early-stage cancer patients are not obvious due to the hidden nature of lung cancer. Clinically, most lung cancer patients have already reached the middle and late stages when they show obvious symptoms. Here, we remind our friends that even if you are not sick, you should pay attention to it. Even if you don’t consider yourself, you should consider your family. The health of your family is your own health.

Eight key points in diagnosing lung cancer

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

2. 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.

3. 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.

4. The early symptoms are not obvious. As the disease progresses, symptoms such as cough, bloody sputum, chest pain, fever, and shortness of breath may appear.

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

6. Late-stage patients experience fatigue, progressive weight loss, and corresponding symptoms caused by the tumor compressing the surrounding tissues, such as hoarseness due to compression of the recurrent laryngeal nerve.

7. 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.

8. Clinically, it is necessary to differentiate some diseases that are easily confused with lung cancer. Pulmonary tuberculosis has symptoms such as cough, blood in sputum, chest pain, and hot flashes. The sputum tuberculosis test is positive and anti-tuberculosis treatment is effective. Pneumonia generally develops quickly and has obvious systemic symptoms. After antibacterial treatment, the symptoms disappear and the lesions are absorbed quickly. In addition, it should also be differentiated from lung abscess, pulmonary pseudotumor, mediastinal tumor, bronchial fluid cyst and pulmonary arteriovenous aneurysm.
