The duration of life of benign nerve sheath tumor is mainly related to the specific location and treatment, which should be analyzed specifically and not generalized. Benign nerve sheath tumor mainly grows on the nerve sheath membrane, with slow growth, regular shape, uniform texture and generally hard or tough texture. If the tumor is small, located on the surface of the body and superficial, it can be removed from surgery and treatment, and it can be observed and reviewed regularly, which usually will not affect the life expectancy. However, if the nerve sheath tumor continues to grow, it can be treated by surgical removal and the patient’s prognosis is usually better. In addition, nerve sheath tumors in the spinal canal or intracranial area, although benign, need to be treated promptly. The gradual growth of the tumor can compress the spinal cord and brain tissue, which can make surgery more difficult and dangerous and can affect the patient’s survival time. Therefore, patients with benign nerve sheath tumors should undergo early surgical removal, and after surgery, they need to pay attention to maintain a good lifestyle, pay attention to rest and regular review.
