The World Health Organization’s cancer research agency classifies processed meats—such as bacon, sausages, ham, and hot dogs—as Group 1 carcinogens, meaning there is strong scientific evidence that they can cause cancer in humans.
Although processed meat is placed in the same category as tobacco smoke, the classification reflects the strength of the evidence, not the level of risk. In other words, it confirms that processed meat can increase cancer risk, but it does not mean it is as dangerous as smoking.
The strongest evidence links regular consumption of processed meat to colorectal cancer, with some evidence also suggesting an increased risk of stomach cancer. Researchers believe this is largely due to processing methods such as curing, smoking, and salting, as well as certain compounds that are formed or added during these processes.
