A couple of years ago, a meta-analysis of RCTs found that taking aspirin daily reduces the risk of dying from cancer by ~20% in middle-aged and older adults.
That’s a curious metric to choose. By that standard taking aspirin is about as healthy as playing a round of Russian Roulette.
It’s a fairly natural metric to choose if one wishes to gauge aspirin’s effect on cancer risk, as the study’s authors did.

Fortunately, the study’s authors and I also interpreted the data by another standard. Daily aspirin reduced all-cause mortality, and didn’t increase non-cancer deaths (except for “a transient increase in risk of vascular death in the aspirin groups during the first year after completion of the trials”). These are not results we would see if aspirin effected its anti-cancer magic by a similar mechanism to Russian Roulette.

Pardon me. Mentioning only curiosity was politeness. The more significant meanings I would supplement with are ‘naive or suspicious’. By itself that metric really is worthless and reading this kind of health claim should set off warning bells. Lost purposes are a big problem when it comes to medicine. Partly because it is hard, mostly because there is more money in the area than nearly anywhere else.

And this is the reason low dose asprin is part of my daily supplement regime (while statins are not).

I recently stopped with the low dose aspirin, the bleeding when I accidentally cut myself has proven to be too much of an inconvenience. For the time being, at least.
I’d assume they mean something like the per-year risk of dying from cancer conditional on previous survival—if they indeed mean the total lifetime risk of dying from cancer I agree it’s ridiculous.
Yeah, pretty much. There are other examples of this where something harmful appears to be helpful when you don’t take into account possible selection biases (like being put into the ‘non-cancer death’ category); for example, this is an issue in smoking—you can find various correlations where smokers are healthier than non-smokers, but this is just because the unhealthier smokers got pushed over the edge by smoking and died earlier.

“All cause mortality” is a magical phrase.

Am I missing a subtlety here, or is it just that cancer is usually one of those things that you hope to live long enough to get?
