There are scientists who argue that what the mitochondria does is fundamentally cancerigenic on a long enough timeline, so in a sense, yes, everything we eat is associated with cancer.
Metabolism is a process with chemical and energetic exhaust that can damage machinery critical to cellular processes. And at some point it becomes evolutionarily favorable to just accept that damage and expend effort starting over again (offspring) as opposed to attempting complete repair of all the damaged systems.
In that way, all metabolic processes will logically lead to cancer (damage to dna). The world is on fire.
