Mulled glass nodules 0.5 cm are generally benign nodules that have a chance of being cured with ablation, but if the nodule is a highly malignant mixed milled glass nodule, then the cure rate will be reduced and recurrence may occur. Generally speaking, ground-glass nodules in the lungs of 0.5 centimeters are considered to be tiny and usually benign, with a small chance of deterioration, and are not particularly serious. Lung microwave ablation is a more effective treatment for this kind of nodule problem, which is less invasive, with high safety performance, and can precisely eliminate the lesion according to the specific range of the lesion, so as to achieve the effect of cure. In addition, it is not absolute as it varies from patient to patient. If this kind of ground-glass nodule is mixed ground-glass nodule, and there is some soft tissue in it, then it is more serious, and the degree of malignancy is relatively high, then even if the ablation surgery is performed, it still can not be able to completely remove the lesion, and there is a possibility of recurrence after the surgery. Therefore, patients should try to timely treatment at an early stage to avoid deterioration of the condition. In addition, special attention should be paid to postoperative care, light diet, early to bed and early to rise, and regular checkups in the hospital, so as to reduce the chances of recurrence.
