Surely in this type of instance (looking at a scan to answer a yes/no question) the human and AI act independently, with the computer being a useful aid because it separately picks up a few of the human's false negatives. Assuming false negatives are a lot worse than false positives, this can only be a good thing.
If they lead to an unnecessary mastectomy then false positives are pretty bad. Not as bad as dying, obviously, but still a severe blow to a woman's identity and sense of self worth.
It's going to be a hard pill to swallow if you have to tell a woman "sorry, we removed your healthy breast because the computer made a mistake."
I think the idea of "screening" is that you don't just race off to a mastectomy the minute some AI model goes off. Of course, putting more false positives through a fallible process of review does run the risk you speak of.
