There are many types of brain tumors. In general, a tumor is an abnormal growth of new cells that buildup to form to a mass of tissue, or a tumor. When this process occurs in the brain, then a brain tumor is formed. These tumors can be benign (noncancerous) or malignant (cancerous). How rapidly the tumor grows, the size of it, how it affects the person, and which treatment is selected depends on the tumor. Symptoms of a brain tumor can include:

Visual problems including

• Blurred vision, double vision, and visual field loss

• Unusual nausea and vomiting
• Difficulty with balance/coordination
• Numbness or paralysis of an arm or leg
• Trouble with hearing and speech
