This is a very interesting concept. I’m not a medical professional so cannot comment on whether photos and AI would diagnose, however this and other sites do get people posting images of their mouth and asking “does this look like cancer” so to them I guess 50c would be a price with paying.
Oral cancer is on the increase. So that’s a factor too.
Please can you say why you selected this cancer? Because it’s a visible one? Or because you or others have been affected by it.
Good luck keep us up to date with how it progresses
