Key clinical point: Aspirin intake may be associated with a reduced risk for incident breast cancer (BC) in adults.
Major finding: Aspirin users vs nonusers had a significantly reduced risk for BC (hazard ratio [HR] 0.91; P = .002), especially estrogen receptor-positive BC (HR 0.90; P = .0004).
Study details: Findings are from a meta-analysis of 28 cohort studies including adults who received aspirin.
Disclosures: This study did not report the funding source. The authors declared no conflicts of interest.
