Why go to the hospital at all? Just take the photo at home.

As someone with a phenotype more subject to skin cancer, I have been using an app called SkinVision for years.

From my anecdotal experience it tends to flag the same moles as dermatologists do, and they have actual dermatologists review images where the model has low confidence, so overall pretty happy with it.

Note that I am not affiliated with them in any way.

   99% accuracy in diagnosing benign case
This is meaningless. The only thing that matters in this kind of application is false negative rate at some acceptable false positive rate.

I assume whoever is working on this knows that, so this is mostly a criticism of the article. That said, this is a horrible use of AI.

I went searching for more. The tool is called DERM by Skin Analytics. They have more info on stats:

I assume if you get a positive response you will want to speak with doctor about it

If the thermometer says 39 C/102 F I will want to speak with a doctor about it but that doesn't mean I want to go to the hospital every time I want my temperature checked.

I suspect it has a lot more to do with these lines:

> medical photographers taking photos of suspicious moles and lesions

I.e. it might not be ready enough or validated for an average person snapping their own photo and:

> The images are then transferred to a desktop computer for greater analysis before the tool determines the result

There is more to it than the phone app and it may not be packaged in a way that is currently worthwhile to distribute to home users.

Both of these (and other things) may change with time of course.
