If there is no change for three years, there is no need for treatment for the time being, and all you need to do is to continue to observe regularly and pay attention to adjusting your physical condition. If there is no change for three years, basically the probability of benign lesions is very high, and the corresponding lesions are relatively stable and have no effect on the physical condition. At present, only regular observation of lesion changes through CT examination is needed, and no special treatment is required. In daily life, we should avoid excessive exposure to dust, quit smoking, and take care of physical conditioning to enhance physical fitness. If the nodules are found to be enlarged or have solid components during the review process, it is necessary to consult a doctor in time to confirm the corresponding lesion type through further clinical examination, and carry out standardized treatment under the guidance of the clinician, so as to avoid delaying the condition.
