How to diagnose early lung cancer? The correct diagnosis method for early lung cancer

Lung cancer is a relatively common cancer and is extremely harmful. The causes of this disease are complex and are generally closely related to smoking, unhealthy lifestyles, and environmental air pollution. Many people do not pay attention to this disease in their lives and do not know much about it. It is difficult to detect the disease in the early stages of the disease, leading to misdiagnosis. For this reason, the following is a detailed introduction on how to diagnose early lung cancer, hoping to help everyone.

First, chest X-ray examination is the first choice of examination. The limit for detecting pulmonary nodules is a diameter greater than 1 cm, and at this time the tumor may have invaded the bronchial epithelium and vascular epithelium. Fiberoptic bronchoscopy is the most commonly used diagnostic tool for obtaining histological evidence of lung cancer, but it has limitations in diagnosing early lung cancer because these lesions are difficult to judge with the naked eye. Fluorescent endoscopy can significantly increase the detection rate of precancerous lesions and carcinoma in situ, and can play an important role in the screening and follow-up of people at high risk of lung cancer, but the examination cost is expensive.

Secondly, sputum cytology uses sputum to look for cancer cells, especially multiple sputum examinations, which is helpful for diagnosing central tumors originating from the large airways, such as squamous cell carcinoma and small cell carcinoma. Peripheral tumors originating from the small airways, such as adenocarcinoma, especially those with a diameter of less than 2 cm, can only be found occasionally by sputum examination, but they are of great significance. The biggest advantage of sputum cytology is that it is non-invasive.

Finally, as the disease progresses, percutaneous biopsy is very accurate in diagnosing malignant pulmonary nodules, but it is an invasive examination and has certain complications, such as pneumothorax and hemoptysis.

With the development of modern medicine, the progress of imaging, bronchoscopy and sputum exfoliative cytology has provided favorable conditions for the early diagnosis of lung cancer. Lung cancer can be discovered early to strive for surgical opportunities, combined with chemotherapy and other comprehensive treatments to improve the patient's quality of life and prolong the patient's life.

After the above experts introduced how to diagnose early lung cancer, patients should also have some understanding. The treatment of lung cancer mainly depends on early detection. If it is in the late stage, the treatment is very difficult. Therefore, it is recommended that patients go for a check-up in time if they feel unwell, choose a method that suits them, and insist on treatment to achieve results!
