How is a tumor removed from the brain?

Craniotomy. Brain tumors are generally removed through the gentle, temporary removal of the skull followed by the dissection of the tumor off the normal brain vessels and nerves using a microscope and computer guidance systems. Each brain tumor is different in consistency and its location and hence the ease of removal is determined by your specific type of tumor.
Carefully. You need to ask your doctor about this. It depends on the size and kind of tumor and location if they will attempt to remove it.
