Cancer risk from grilling, however, is real, but it changes dramatically with what you grill and how you do it. The problem with traditional grilling comes from the combination of meat with intense heat. Whether you are using red meat, poultry or seafood, substances in the muscle proteins of these foods react under high heat to form carcinogenic compounds called heterocyclic amines (HCAs). HCAs can damage the DNA of our genes, beginning the process of cancer development. Consumption of HCAs is mostly clearly linked to cancers of the colon and stomach. One study found that people who eat the most barbecued red meat (beef, pork and lamb) almost doubled their risk of colon polyps, compared to those who did not eat these foods. Colon polyps can develop into colon cancer. Some evidence also suggests that these carcinogenic compounds can travel through the bloodstream to other tissues. This would explain why HCAs could be a factor in breast cancer and other cancers.
