That seems... ok?
It might even be a good thing. With enough regular feedback, we might emotionally adjust to the realization that "maybe you should get checked out" is not OMG I'm going to die.

b) "Get checked" may itself cause problems, for example: Scans for breast cancer involve radiation which may actually cause cancer. Biopsies can also be quite invasive. Obviously the risk is low, but depending on the exact numbers and it might actually be better to not get screened until one is in a known high-risk group (where the base rate fallacy doesn't skew the results so much).

a priori
There's a very popular trend to imagine genetic components in every human behavior. It's not just incorrect, it's very dangerous.

That's easily handled using common practices. If breath and* blood test are positive do CT scan.
