These devices are NOT DIAGNOSTIC for cancer, they are discovery devices. While the VELscope is more sophisticated, if you don't know what you are looking at, these things are not going to be a substitue for knowing what you are looking at. They will find EVERYTHING including pizza burns, and cheek bites. You have to understand how to do a proper screening first, they are ADJUNCTIVE devices. They will find leukoplakia, lichen planus, herpes simplex and the list goes on and on.
