Moreover, the results of logistic regression of the association between BC and dietary intake based on FTO genotype showed that there was no significant association between dietary intake and BC in individuals without risk allele after adjusting confounding variables including age, breastfeeding duration, first menstruation age, post‐menopause age, breast cancer family history, number of pregnancies, smoking, using alcohol drinks and physical activity (Model 1). This evidence concerns the gene FTO and breast cancer.
