Processed meat (IARC classification)

In the body: IARC classes processed meat as carcinogenic to humans, for colorectal cancer. That is how sure the evidence is, not how big the risk is.

Not rated by dose: a flag on 3 reviewed foods, among them Bacon, pan-fried, Ham, sliced and Deli turkey breast.

Background. Shown, not scored: no dose basis at normal intake, a classification rather than a risk, or legal limits only.
