What does a biopsy for a brain tumor involve?

My friend's daughter has a brain tumor and they're going to perform a biopsy to see whether or not it's cancerous. What does a biopsy typically involve, especially if the patient is a child?

There are different ways to perform a brain biopsy. Generally, either "Open" by making a small window in the brain that enable the surgeon to actually see the brain surface, or "Stereotactic", which is imaging-guided and performed through a very small incision and obtain small cores of tissue with a biopsy probe that is blunt on the tip and sucks a small piece of tissue in from the side of the probe near the tip.
