How do surgeons avoid damaging the brain during tumor surgery?

Neurosurgeons take great care to protect normal brain tissue. First, detailed imaging (MRI, etc.) helps us plan a safe path to the tumor. During surgery, we often use a powerful operating microscope for magnification, giving a very clear view of tiny structures. We also utilize neuro-monitoring – attaching electrodes to monitor brain and nerve function in real time – so if we get too close to critical areas, we know immediately. For tumors located in or near vital regions (like areas controlling speech or movement), we might employ an awake surgery technique as mentioned, where the patient can respond to tasks during the operation. This way, we map out essential brain functions and remove the tumor without causing neurological deficits. By combining these strategies, surgeons are able to maximize tumor removal and minimize risks of injury to the brain.
