Palliative surgery refers to the surgery that the tumor can no longer be completely resected and is not aimed at curing, but only used to relieve pain and alleviate symptoms. When patients with malignant tumors cannot be completely resected or the tumors have already metastasized or the patients are relatively old and in poor physical condition and cannot undergo resective surgeries, palliative surgeries can be performed so as to relieve the symptoms caused by the tumors, improve the quality of life of the patients, and prolong the survival cycle of the patients. The more common palliative surgery is intracranial tumor, the patient’s multiple tumors in the skull lead to increased intracranial pressure, cerebral edema is serious, the need for debridement decompression surgery, can reduce the intracranial pressure, improve the symptoms of brain herniation, so as to play a role in prolonging the life of patients with malignant tumors in advanced stages. Palliative surgery is a surgical procedure to remove the fatal threat of tumor to patients. Palliative surgery includes palliative tumor resection and decompression surgery, both of which can win survival time for patients and ensure quality of life. Therefore, it is recommended that patients can choose the suitable treatment for themselves.
