Bronchoscopy is possible for some lung cancer patients. It is a misconception that bronchoscopy is not recommended for lung cancer. A part of central lung cancer is suitable for bronchoscopy, so that the tissue can be removed for biopsy and the patient’s condition can be clarified. Lung cancer is a common malignant tumor of the respiratory system in clinic, and the typical clinical symptoms are blood in sputum, cough, chest tightness and so on. If lung cancer is suspected, one should go to the respiratory department or thoracic surgery department of the hospital as soon as possible to improve bronchoscopy, chest CT and other related tests and examinations to clarify the severity of the patient’s condition. Early stage lung cancer can consider surgery to remove diseased tissues, while middle and late stage lung cancer can cooperate with doctors to receive comprehensive treatment such as chemotherapy, radiotherapy and targeted therapy.
