3. Common Conditions Treated by Neurosurgeons
Neurosurgeons treat a wide range of conditions affecting the brain, spinal cord, and peripheral nerves. These conditions can be congenital (present at birth), the result of trauma, or develop over time.
3.1. Brain Tumors
Brain tumors are abnormal growths in the brain that can be benign (non-cancerous) or malignant (cancerous). Neurosurgeons play a critical role in diagnosing and surgically removing brain tumors. They also work with other specialists, such as oncologists and radiation therapists, to develop comprehensive treatment plans.
3.2. Spinal Cord Disorders
Spinal cord disorders can result from trauma, degenerative diseases, or tumors. Neurosurgeons treat conditions such as:
- Herniated Discs: When the soft cushion between the vertebrae pushes out and compresses nearby nerves.
- Spinal Stenosis: Narrowing of the spinal canal, which can put pressure on the spinal cord and nerves.
