The impact of minimally invasive lung nodule surgery on lung function varies and is based on the benign or malignant type of nodule. Lung nodules include many types. For benign lung nodules, minimally invasive surgery only requires removal of the nodule, and relatively little lung tissue is removed, so there is generally no impact on lung function. Lung nodules also include lung cancer. When doing minimally invasive surgery, radical lung cancer surgery is needed to achieve the goal of eradication, which involves the removal of a relatively large amount of lung tissues, as well as the clearing of regional lymph nodes, or else there is a possibility that the lung cancer may recur or metastasize. Since relatively more lung tissues are removed, it will affect the lung function and lead to the decline of lung function. After minimally invasive surgery for lung nodules, it is necessary to follow the doctor’s instructions to carry out rehabilitation exercises, so as to recover to a satisfactory state of lung function as far as possible.
