How many years does a doctor follow up after removal of a non cancerous meningiona brain tumor? I'm 64. Thanks! Meningioma brain tumor

Depending on grade. It depends on the pathology report and how well the tumor came out. If yours was who grade 1 (very benign) and the surgeon removed all with attached brain membrane, follow up scan up to a few years will be plenty. Please discuss with your surgeon and follow his instruction.
