If you have symptoms of a brain tumor, your doctor will first ask questions about these symptoms. Next, the doctor will get your complete medical history and give you a physical exam. In addition to checking your overall health, the doctor will do a neurological exam to observe the way you walk, talk, and move.
The doctor may examine your eyes to look for any swelling caused by pressure on your optic nerve. The optic nerve connects the eyes to the brain. This swelling is called papilledema. It is a sign that requires immediate medical attention.
Diagnosis of glioma involves:
- A medical history and physical exam: This includes questions about the patient’s symptoms, personal and family health history.
- A neurological exam: This exam test vision, hearing, balance, coordination, reflexes, and the ability to think and remember.
- Scans of the brain: Magnetic resonance imaging (MRI) and computed tomography (CT or CAT scan), which use computers to create detailed images of the brain, are the most common scans used to diagnose brain tumors.
- A biopsy: This is a procedure to remove a small sample of the tumor for examination under a microscope.
