Yes, this freaks me out too, and makes the vast majority of humans insane for not taking care of their health... all the more reason to be vigilant, not complacent.

People eventually die. If they don't die of cancer, they die of heart disease, or liver failure, or some other part of their body wearing out. So those stats don't freak me out... the relevant ones are how many people under 75 or so get a disease.
