Epidemiologic studies have linked energy balance to an increased risk of breast cancer, yet few studies have investigated potential mediators of this association with Chinese women. We examined the above association by blood levels of insulin-like growth factors (IGFs), binding proteins, and C-peptide in the Shanghai Breast Cancer Study...
