Abstract

Previous studies have suggested that egg consumption may increase the risk of colorectal cancer and some other cancers. However, the evidence is still limited. To further explore the association between egg intake and cancer risk we conducted a case-control study of 11 cancer sites in Uruguay between 1996 and 2004, including 3,539 cancer cases and 2,032 hospital controls. In the multivariable model with adjustment for age, sex (when applicable), residence, education, income, interviewer, smoking, alcohol intake, intake of fruits and vegetables, grains, dairy products, fatty foods, meat, energy intake and BMI, there was a significant increase in the odds of cancers of the oral cavity and pharynx (OR= 2.02, 95% CI: 1.19-3.44), upper aerodigestive tract (OR= 1.67, 95% CI: 1.17-2.37), colorectum (OR= 1.64, 95% CI: 1.02-2.63), lung (OR= 1.59, 95% CI: 1.10-2.29), breast (OR= 2.86, 95% CI: 1.66-4.92), prostate (OR= 1.89, 95% CI: 1.15-3.10), bladder (OR= 2.23, 95% CI: 1.30-3.83) and all cancer sites combined (OR= 1.71, 95% CI: 1.35-2.17) with a high vs low egg intake. We found an association between higher intake of eggs and increased risk of several cancers. Further prospective studies of these associations are warranted.
