What is the success rate of brain tumor surgery?

The success rate of brain tumor surgery depends on the type of brain tumor, where it is located and the patient's current health, according U.S. News and World Report. The main objective of brain tumor surgery is to take out as much of the tumor without damaging healthy brain tissue.

Although in the past neurosurgeons have relied on visual clues to distinguish healthy brain tissue from the tumor, recent advances in surgical navigation technology allow a surgeon to study a computerized map of the patient's brain in the operating room as a guide during surgery, reports U.S. News and World Report. Such advances have reduced the risks of complications or damage to healthy brain tissue.
