The specific need for surgery for benign brain tumor in 70s needs to be decided according to the patient’s own situation and the severity of the disease, and cannot be generalized. If the patient’s brain tumor is small in size and does not cause symptoms or has mild symptoms, then dynamic observation and regular review can be considered, and surgery can be withheld for the time being. If the benign brain tumor is large in size and has caused pressure on the brain tissue, resulting in increased intracranial pressure and neurological dysfunction, or if the tumor has significantly increased in size or has a tendency to malignant transformation, and if the patient is able to tolerate the surgical treatment after the preoperative evaluation, the patient can undergo surgical treatment. In the case of benign brain tumors in people in their 70s, it is important to seek timely medical attention and follow the doctor’s advice to decide whether surgical treatment is needed.
