And what is the marginal impact on that 50% from eating non-processed meat? That’s the crucial missing piece of information. If the difference is between 50% and 50.00001% then I don’t care.Cancer is the leading cause of death, so any increase in risk should be thought about carefully, whether it is relative or absolute.
Lifetime risk of getting cancer is about 50%, is that high enough for you?
Literally everything you do increases your risk of cancer, by the way. Cancer results from runaway cell reproduction, which is an event potentially triggered in your body every time it comes across anything that isn’t “normal”, which basically includes everything. You have systems designed to destroy problem cells but sometimes, very rarely, those systems fail and a cancer starts. That’s why the lifetime risk aggregates to 50%. It’s also why you can’t just spit activities into “cancer forming” and “non cancer forming”. To have an idea of whether an event matters, you need to know the marginal effect, not just whether or not it has an effect at all.
