How to diagnose lung cancer? It is recommended to do the following tests to confirm lung cancer

There are many factors that cause lung cancer. Early diagnosis is the best time to get effective treatment. Clinically, many people are diagnosed in the middle or late stages of the disease, which often delays the best time for treatment. Therefore, it is important to pay attention to the early diagnosis of the disease. So, what are the diagnostic methods for early lung cancer? Experts can introduce it in detail.

X-ray fluoroscopy is a diagnostic method for early lung cancer. Hilar lung cancer, especially squamous cell carcinoma, can be directly observed with a fiberoptic bronchoscope. However, for field lung cancer, which is mainly adenocarcinoma, it is impossible to observe many cases. Tissue can be collected under X-ray fluoroscopy, or cells can be brushed off with a brush for cell brushing.

What are the diagnostic methods for early lung cancer? While directly confirming the presence of the tumor, tumor tissue can be taken. If it cannot be directly observed, tumor cells and tissue examination can be taken while performing X-ray fluoroscopy.

Endoscopic examination (fiber bronchoscopy) combined with chest X-ray, CT and other examinations is one of the early diagnostic methods for lung cancer. It can detect very small tumors. Generally, in order to confirm the diagnosis, cancer cells and tumor tissues must be taken for diagnosis under a microscope, which includes histological examination and cytological examination.

Percutaneous cytology is a diagnostic method for early lung cancer. For field lung cancer that cannot be diagnosed with fiberoptic bronchoscopy, after the tumor is seen under X-ray fluoroscopy and CT, a needle can be inserted from the outside of the body to take the tumor tissue for tissue and cell examination.
