The "better safe than sorry" approach may not be the best one when it comes to brain scans. That warning comes from doctors.
They say some people with no symptoms of disease in the brain buy brain scans to check to see if something *might* be wrong. They need to know just in case.
If your doctor doesn't recommend you have a scan or if you don't have any symptoms it might not be worth the trouble. A look at 20 thousand scans of people who didn't have symptoms found around 3 percent had something unusual. But that doesn't mean they needed brain surgery.
Doctors say it's important to consider when it comes to the brain, treatments for abnormalities like aneurysms and benign tumors may do harm as well as good. Stay safe and healthy.
