Similar with self-driving cars, they may work with (made up number) 99% accuracy, but that 1% is still too risky.

Regardless of what the AI says, I would still ask a doctor to see my scan considering a false-negative could cost me my life and a false-positive would probably mean a doctor would double check it anyway.

The bottleneck would still be the person who looks at each scan personally.

That being said, I think there is huge potential in early risk prediction using ML long before a real human could even spot cancer tissue.
