Making the Diagnosis
Doctors use a number of techniques or procedures to determine if a person has a brain tumor. First, a doctor performs a physical examination and asks about the person's medical history. If a brain tumor is suspected, the person will likely be referred to a neurologist. The neurologist will likely perform neurological tests to determine how the nerves in the brain and spinal cord are working. Other tests used may include:
- blood tests
- chest X-ray
- computed tomography (CT or CAT) scan (if a tumor is present, it will show the location)
- magnetic resonance imaging (MRI) (not always performed)
- electroencephalogram (EEG)
- a tissue sample from the tumor to determine the type
For low-grade astrocytoma tumors, magnetic resonance imaging (MRI) is often the best way to see the tumor. High-grade astrocytoma tumors are best viewed with a CT scan. The grade of the tumor can also be determined by looking at the cells under a microscope.
If a brain tumor is diagnosed, the best method of treatment must be determined. It should be determined whether it is safe for the person to drive.
