TIL that 40% of cancers are preventable.

  Which reduces your risk from roughly .5% down to .3% by age 49. https://www.cancer.gov/about-cancer/causes-prevention/risk/age https://www.cancer.gov/about-cancer/causes-prevention/risk/a...

  Not opposing or anything but how do you even measure that? Really asking to see if anyone knows / has an idea.

    I don't know off-hand, but probably a longitudinal survey of cases and pretty rough estimates. It is probably made a bit easier by there being some big chunks which are (likely) more clearly attributable to behavioral choices: smoking-related, sun exposure, and probably some occupational (chemical exposure, etc.).

    It’s pretty straight forward— you compare the average risk for individuals to the rates for those exposed to carcinogens. For instance, if a population of people develops lung cancer at a rate of 2% by age 70, and a population of smokers has a rate of 10% by age 70– the difference between the base line and the exposed populations becomes the “preventable” count.
