Meat is an animal product with muscle fibers, fat and blood. The blood releases a product called Heme Iron. This Heme Iron enters the cells and generates free radicals that can lead to DNA alterations, if you only eat raw meat. So raw meat, especially red meat, can cause cancer because of the Heme Iron.
But as people don't usually eat raw meat, heating it can generate heterocyclic amines and polycyclic aromatic hydrocarbons, which in digestion form N-nitroso and these are all carcinogenic products.
In this way, heating meat and then eating it enhances the products that induce cancer in the body.
So, as well as eating meat, it is a product that destroys nature, and it also helps to produce cancer, especially of the colon.
