TH1 and TH2 cytokines dataset in insulin users with diabetes mellitus and newly diagnosed breast cancer

Abstract Exogenous insulin use may interfere with the T helper cells’ cytokine production. This dataset presents the relationship between pre-existing use of injectable insulin in women diagnosed with breast cancer and type 2 diabetes mellitus, the T-helper 1 and 2 produced cytokine profiles at the time of breast cancer diagnosis, and subsequent cancer outcomes. A Pearson correlation analysis evaluating the relationship between T-helper cytokines stratified by of insulin use and controls is also provided.
