What should I do if I have a nodule on my lung? In recent years, with the widespread use of chest CT with physical examinations, many people with no symptoms are found to have lung nodules. Studies have shown that more than 97% of lung nodules are benign lesions and less than 3% of lung cancer. Therefore, there is no need to be overly concerned, resulting in overdiagnosis and overtreatment. For the management of lung nodules, the main treatment methods are: follow-up observation, thoracoscopic surgery and microwave ablation. Thoracoscopic surgery is commonly known as “hole punching surgery”, which can be done by punching a hole in the chest, and it can be done in municipal hospitals and even in some county hospitals. Microwave ablation has been used for the treatment of pulmonary nodules in recent years. It is easy to perform and is a good choice for people who cannot or do not want to undergo surgery.
