The Specific carncer Link — What the Research Shows
The strongest and most consistent evidence links processed meat consumption specifically to colorectal carncer — carncer of the colon and rectum. Each year, approximately 150,000 Americans alone are diagnosed with colorectal carncer, making it one of the most common and deadly carncer in the developed world.
The numbers from the research are sobering and specific. According to the WHO's review, eating just 50 grams of processed meat per day — roughly equivalent to one hot dog, just under two strips of bacon, or about six thin slices of deli ham — is associated with an 18 percent higher risk of developing colorectal carncer. Research from the World carncer Research Fund and the American Institute for carncer Research went further, finding that eating 3.5 ounces (approximately one large hot dog) of processed meat every day raises colorectal carncer risk by 36 percent compared to someone who eats no processed meat. At 7 ounces per day, the risk climbs to 72 percent higher.
Beyond colorectal carncer, emerging research suggests processed meat may also be associated with elevated risks of stomach carncer, pancreatic carncer, breast carncer, prostate carncer, and carncer of the esophagus and lung — though the evidence for these links is currently considered less definitive and requires further investigation.
Why Does Processed Meat Cause carncer?
The carncer-causing mechanisms in processed meat are multiple and overlapping, which is part of why the scientific community has reached such consistent conclusions across so many different studies conducted in different countries with different populations.
