Red Meat
The problem with processed and red meat plays out mainly in the colon: N-nitroso compounds from curing, together with the oxidation that heme iron promotes in the gut, are thought to damage the DNA of the cells lining the bowel. The International Agency for Research on Cancer (IARC) classifies processed meat as Group 1 and red meat as Group 2A carcinogens; the grades describe how certain the evidence is, not how large the harm is.

A single food on its own rarely decides whether you get cancer. Even processed meat and alcohol — which the International Agency for Research on Cancer (IARC) lists as Group 1 carcinogens (the evidence that they cause cancer is certain; the label says nothing about how large the harm is) — raise the odds through the amount taken over many years, not through any one meal.

This plays out at the level of cells: cancer is cells multiplying out of control after years of accumulated genetic damage, and cancer is an umbrella term for hundreds of different diseases — colorectal, breast and liver cancers all differ in mechanism. What diet actually does is slowly shift the probability of disease across a population: long-term eating patterns make certain cancers somewhat more or somewhat less likely.

What this means for you: do not expect one food to save you or doom you. Put your effort into long-term patterns, where the payoff is real but modest; if anyone guarantees that eating something will keep you free of cancer, treat the claim with suspicion from the start.
