@isilzha314 So to break down your arguments:

Blood work and cancer screenings: Screening is not the same as "cure", not even close. Even then, by the time something shows up on either, there is already a disease there to treat or cure.

Osteoporosis screenings: Same thing, loss in bone density is a disease, even if it's not symptomatic yet.

Maintenance medication: Again, things like high blood pressure are conditions that can cause cascading problems, and should absolutely be treated.
