Narrative: Case study 27.11 summary
In a magazine article, three research groups reported a link between cured-meat consumption and cancer.Among 232 cases in one study, children who ate 12 or more hot dots in a month were nine times as likely as hot dog-free controls to develop leukemia.Researchers also found an increased risk for kids whose fathers ate a lot of hot dogs.Another study involving 234 cases of various childhood cancers found that children whose mothers ate hot dogs at least once a week were twice as likely as controls to develop brain tumors.The results may be due to the N-nitroso compounds in cured meats, researchers say.However, they warn that the studies are far from conclusive.
