Whether a 70-year-old patient with benign meningioma should undergo surgery depends on whether the tumor has caused clinical symptoms and whether the tumor has a tendency to continue to grow, etc. Surgery is generally required. If the meningioma does not cause obvious clinical symptoms and the tumor does not have a tendency to continue to increase in size, and the patient is too old to tolerate surgery, surgery can be performed without urgency, and regular follow-up with brain MRI is sufficient. For meningiomas that have already caused obvious symptoms (such as headache, mental disorder, limb movement disorder, visual field change, etc.), or have been found to have a tendency to increase in size through follow-up observation, they should be treated with surgery in a timely manner, and if the patient is unable to tolerate craniotomy due to his/her advanced age, he/she can choose Gamma Knife treatment. It is recommended that patients with meningiomas should consult a doctor for a comprehensive assessment of their condition to determine whether surgical treatment is needed.
