Purely hypothetically: access to affordable medical insurance becomes contingent upon such a scan. You have a developing condition which will render you uninsurable.
I'm not suggesting Google would or even legally could consider creating a bidding system for insurance companies to use clean scans as a leadgen system, but in the unlikely event that they did feel so inclined, it wouldn't exactly be a wild departure from their business model
