Large observational study suggests prolactin-increasing antipsychotics are associated with increased risk of breast cancer (OR=1.56 for over 5 years of exposure); prolactin-sparing antipsychotics (including clozapine, quetiapine, or aripiprazole), on the other hand, were not associated with increased risk.

Nested case-control study: ≥5 years exposure to prolactin-sparing APDs was not associated with an increased risk of breast cancer vs.<1 year exposure (aOR=1.19; 0.90–1.58). The opposite was observed with APDs that increase prolactin (aOR=1.56; 1.27–1.92) https://t.co/LwCVyTH051
