One day your smart phone may be able to help diagnose-- mouth cancer.
Researchers at Stanford University are working on an app for that!
How it would work is a device attached to your phone could take a photo of the inside of your mouth.
That picture could be sent to dentists who could see if any lesions might be cancerous.
The screening tool is still being tested.
The idea is to use the scanner in places where it's hard to get a dental checkup.
