The common symptom of early stage of lumbar spine malignant tumor is mainly local pain symptom. Depending on the severity of the disease, the pain symptom may be mild or severe, and even some patients do not have obvious pain yet. When lumbar spine malignant tumor progresses, pain in the lumbar region will appear, which may occur during activities or resting, especially at night, and often affects sleep when it is serious. In addition, if the patient’s back pain is not caused by trauma or strain, and the patient is not very old, he or she must be able to go to the hospital for examination to see if there are bone changes in the lumbar spine. Lumbar spine tumors include local primary malignant tumors as well as metastatic tumors of malignant tumors of other organs of the body. If there are other systemic malignant tumors accompanied by pain in the lumbar region, malignant metastases of the lumbar spine should be highly suspected.
