Why is Stereotactic Biopsy Needed?
Two days before the procedure, you will need to get an MRI or CAT scan of the affected area. Your doctor will use this scan as a map to locate the lesion.

Once the procedure is complete, your doctor will use a microscope to examine these cells and make a diagnosis.
