The researchers conclude that there is a modest increase in the rates of malignancy and mortality during the first year following a diagnosis of celiac disease. After one year, however, most of that increase quickly diminishes to a level that is only slightly higher than that of the normal population, presumably due to the effects of a gluten-free diet. In an unexpected finding the researchers also found a significant reduction in incidence of breast cancer in those with celiac disease, which warrants further study, as it could provide insight into the cause of the disease.
