> Plus, even for the cancers we do have screening for, it's often not frequent enough to catch more aggressive variants early - a lot of these screenings are only once every ~2-5 years.
Screening intervals are based on doubling time.
> The idea of, say, proactively taking MRIs, blood panels, etc. on people, looking for early stage cancer (and other conditions) throughout the body is not something that's available.
You can pay out of pocket for a “screening MRI” in BC but from my clinical practice the yield is dubious.
> You can't even get an annual physical with a family doctor anymore,
Evidence has shown the physical is useless.
> there's only screening for a handful of specific diseases, and only once you reach certain ages/risk factors
Screening needs pretest probability and a diagnostic test with sufficient accuracy. It simply does not exist for most cancers. Trials are underway for new tests like cfDNA but in 2024 there aren’t any validated options.
