Antipsychotics, through their antagonism of dopamine D2 receptors, can elevate prolactin levels [13,14].While a definitive causal relationship between antipsychotic use and breast cancer remains elusive, epidemiological studies suggest that prolonged exposure to antipsychotics, particularly those with prolactin-elevating properties, may elevate breast cancer risk [15]. The gene discussed is DRD2; the disease is breast cancer.
