When bone metastasis occurs in patients with ground-glass nodule, lung cancer is considered to cause ground-glass nodule, and bone metastasis occurs in patients, which indicates that lung cancer is in advanced stage, often losing the chance of surgical treatment, and local radiotherapy and chemotherapy and comprehensive treatment are needed. Bone metastasis of lung cancer indicates that lung cancer has already reached advanced stage, so surgery to remove lung cancer is of little significance. Even if the primary lesion of lung cancer is removed, it has already been transferred to the bone, so there is no way to operate, and at this time, local radiotherapy can be considered, so as to kill cancer cells as much as possible, and patients who have been treated with radiotherapy tend to be weak in body quality, so they need to strengthen the nutritional therapy. Therefore, patients usually need to strengthen, eat more protein-rich food, eat less greasy, spicy and stimulating food, avoid staying up late and laboring, and take reasonable rest, which is helpful for prolonging patients’ life and improving the quality of life, and if there is any discomfort, go to the hospital in time, so as to avoid delaying the treatment.
