Surgery is not always necessary for ground-glass lung nodules, and is not required if they are caused by benign disease. If the tumor is metastatic, it is also treated with a combination of treatments, and is rarely surgically removed. There are many reasons for the appearance of pulmonary ground glass nodules, including benign and malignant diseases. Common benign diseases include lung inflammation, nodular disease, tuberculosis, etc., which are mainly treated by internal medicine and do not require surgical resection. For grinding glass nodules suspected of primary lung cancer, early surgical resection is recommended to avoid tumor progression and metastasis. Usually, primary lung cancer with ground-glass nodules is in the early stage of carcinoma in situ or cancer, and generally does not require adjuvant treatment after surgery. Ground-glass nodules may also be metastatic foci formed by malignant tumors from other parts of the body. If metastatic tumors indicate that the cancer is already in the advanced stage, comprehensive treatment, including chemotherapy, radiotherapy, targeted therapy, immunotherapy, etc., can be carried out for individual patients who are physically fit to have metastatic foci resected, which can reduce the load of the tumor and prolong the survival period. Patients who find ground-glass lung nodules are recommended to go to the hospital as soon as possible for consultation, so that the nature of the nodules can be clarified as soon as possible and then targeted treatment can be given.
