A brain tumor is an abnormal growth of cells in the brain or skull that can be benign (non-cancerous) or malignant (cancerous). Brain tumors can develop in many areas of the brain, including the brainstem, sinuses, nasal cavity, and skull base. There are over 120 different types of brain tumors, depending on the tissue they originate from.
