A Brain Tumor is an uncontrolled growth of cells in the brain. These can include tumors that have started in the brain or tumors that have started in a different part of the body and have metastasized (traveled) to the brain. In some instances these tumors can be benign (non-cancerous) and only need periodical supervision, while some tumors can be malignant (cancerous) and need further treatment.
Surgery is usually the initial treatment for most benign and malignant tumors. It is performed when the tumor can be removed without unnecessary risk of other neurologic damage. One surgical operation performed is a craniotomy. This is where part of the skull is temporarily removed to access the brain allowing the neurosurgeon to remove as much as the tumor as possible.
