Lung cancer has the greatest mortality rates among both men and women and is the primary cause of cancer-related fatalities globally. Roughly 85% of occurrences of lung cancer are caused by smoking, making it the primary cause of the disease. Lung lesion analysis and, in the event that cancer is proven, therapy are becoming more and more necessary due to the rising usage of chest CT scans and lung cancer screening programs. The one-stop outpatient bronchoscopic technique, which includes tumor navigation, confirmation of malignancy, and prompt treatment, is a desirable future concept. A number of innovative ideas for bronchoscopic diagnosis and treatment are presently being considered in order to add to this idea. Better bronchoscopic navigation to the target lesion is crucial since most suspected malignant lung lesions originate in the lung's periphery. Thankfully, sophisticated bronchoscopic navigation techniques are becoming clinically available, and the discipline of interventional pulmonology is fast developing, allowing for an increasingly accurate tissue diagnosis of lung abnormalities. Furthermore, a number of bronchoscopic therapy techniques are presently being researched.
