This is purely anecdotal on the doctors behalf. There are companies like Annalise.ai which are using hundreds of radiologists to train models for just one type of cancer, and the best they can do is sanity check, so far. This is likely one of those cases. There is a role for AI in this process, but it still requires a radiologist to interpret.

The bigger issue than finding cancers you missed is actually false positives, finding cancers that aren't really there. Thats a much harder problem. Imagine having to get a breast biopsy for a cancer that doesn't exist. That's the state of the art today.
