Processed Meats Linked to 80% of Colon Cancer Cases, Says Veteran Oncologist
A veteran oncologist who operated for 17 years reportedly found that about 80% of colon cancer patients regularly ate processed meats like sausages and hot dogs. Processed meats contain nitrates/nitrites that form N-nitroso carcinogens, which can damage the bowel lining and raise cancer risk. The World Health Organization classifies processed meat as a Group 1 carcinogen, and studies have shown increased risk with consumption (about 18% per 50g/day and around 32% per 75g/day). Health bodies advise limiting processed meat as colon cancer rates rise, including among younger people.
