Cereals consumption and risk for renal cell carcinoma: Can be hypothesized a role of mycotoxins?

This letter to the Editor is the reaction of the previously printed paper "Food groups and renal cell carcinoma: a case-control study from Italy" by Bravi et al. (Int J Cancer 2006 ; 120:681-5). In this study it was found that the incidence of renal cell carcinoma is higher in persons with high consumption of cereals. In the Letter to the Editor we suggested that this fenomenom may be due to the higher exposure of such persons to the carcinogenic and nephrotoxic mycotoxins ochratoxin A and fumonisin B1.
