abstract：:Breast cancer incidence is increased in women with both high and low birth weight. The latter is also associated with hyperglycaemia, insulin resistance and type-2 diabetes, each of which independently increases breast cancer risk. We showed previously in our model of poor early-growth that pregnancy estradiol levels ...

Since Se exerts its biological roles through the selenoproteins, genetic variations in selenoprotein genes may influence susceptibility to CRC.
