The problem with human pattern recognition is not the accuracy itself. A big problem is that 1. human experts are not consistent between themselves and worse 2. not even consistent if they have to evaluate a case repeatedly. One would expect an AI error to be systematic and not changing between predictions. In the short term, an AI (as in Augmented Intelligence) approach would be a good intermediate. Another advantage of AI diagnostics could be its availability in smartphones, especially with skin cancer that could be useful to quickly check marks and spots. Already doctors are advising people to self-check for unusual marks etc., and usually a very big problem is that people wait too long before seeing a doctor.
The problem with that last bit is that there's also the issue of convincing doctors that you suspect something's wrong. Sometimes, doctors don't take patients seriously when they're concerned about something, or don't make more than a cursory glance at the situation before figuring that the patient is overreacting or something. I've been dealing with some breath/lung related problems for a few months now, and I still have to tell my doctors that yes, I have issues breathing sometimes, and yes there's something going on.
Doctor-patient trust is a big issue, especially when the former doesn't take the latter seriously.
