could develop cancer
from excessive radiation doses.
Can I get a brain scan?
Magnetic resonance imaging (
MRI
) of the brain is a safe and painless test that uses a magnetic field and radio waves to produce detailed images of the brain and the brain stem. An MRI differs from a CAT scan (also called a CT scan or a computed axial tomography scan) because it does not use radiation.
Can a brain scan show depression?

so-called ‘eyes-to-thighs’ scan.

chemotherapy
, hormonal treatments, anticonvulsants, and pain medications. Chemotherapy works to shrink or eliminate brain tumors, while the other prescription medications are used to control symptoms while the tumor is being treated.
Can an EEG detect a brain tumor?

brain activity
that might be useful in diagnosing brain disorders, especially epilepsy or another seizure disorder. An EEG might also be helpful for diagnosing or treating the following disorders: Brain tumor. Brain damage from head injury.
