Summary
A large European study suggests that even small increases in processed meat intake may raise the risk of certain cancers. Researchers tracked over 450,000 adults for about 14 years. They found that eating just one extra serving—about a slice of ham, bacon, or sausage—each day was associated with higher risks of stomach and esophageal cancers. The study showed a 9% rise in stomach cancer risk and a 13% rise in esophageal cancer risk per added 30 grams of processed meat. Scientists also observed differences between men and women. Experts caution that while the link is concerning, dietary habits and other factors also influence risk.
