What diagnostic methods can confirm lung cancer? Three diagnostic methods can detect lung cancer as early as possible

Lung cancer is a type of cancer that is seriously harmful to the human body. It is important to detect the disease early and treat it in time. Usually, doctors must first determine the stage of development of the disease in order to decide on an effective treatment plan. It can be seen that effective diagnosis of this disease has a great relationship with treatment, so it is important to pay attention to the diagnosis of this disease. So, what are the diagnostic methods for lung cancer?

(1) X-ray examination: X-ray examination is one of the diagnostic methods for lung cancer. Through chest X-ray examination, the location and size of lung tumors can be understood. Ordinary chest X-rays can clearly show the density, boundaries, location and other characteristics of the tumor. Therefore, doctors usually let lung cancer patients take chest X-rays first, and then use chest CT scans for further examination to understand the location and severity of the lesion.

(2) Sputum cytology: Exfoliated cancer cells can be found in the sputum of most patients with primary lung cancer. Sputum cytology is an effective method for diagnosing lung cancer. In order to effectively diagnose lung cancer, the sputum should not be just saliva, but real sputum from deep in the lungs.

(3) Fiberoptic bronchoscopy: This method can directly observe the pathological changes of the bronchial lining and lumen of lung cancer. When a tumor or cancerous infiltration is found, tissue from the lung cancer patient is extracted for pathological section examination, or bronchial secretions are aspirated for cytological examination to confirm the diagnosis. Fiberoptic bronchoscopy before surgery can help determine the location of the lesion in lung cancer patients.
