Multiple ground glass nodules are nodules found in the lungs during a lung CT, which resemble ground glass. If the nodules are small, they can be observed periodically, usually once every three to six months, and if the nodules are large, a percutaneous lung biopsy may be required to determine the nature of the nodules. If the puncture result is malignant, it is considered to be a malignant tumor of the lung. It is necessary to actively improve the relevant examinations and perform radical resection of the tumor, together with lymph node dissection, and later chemotherapy, targeted drug therapy, Chinese medicine therapy and radiotherapy may be required according to the pathological results. During the treatment period, patients should not smoke, drink alcohol and try not to eat spicy food.
