This interventional mediation analysis identifies inflammation and sex-steroid hormones as the key biological pathways through which adiposity increases the risk of post-menopausal oestrogen receptor-positive breast cancer. Using data from 1,260 post-menopausal females in the Melbourne Collaborative Cohort Study, the researchers demonstrated that interventions shifting inflammation and sex-steroid hormone levels in females with obesity to those of normal-weight females would avert 16.4 and 13.0 excess cases per 1,000, respectively, whereas the insulin pathway showed no significant mediating effect. These findings offer a mechanistic rationale for targeting inflammation and hormonal pathways in obesity-reduction strategies, directly informing the design of public health interventions and precision prevention programs that align with your expertise in translating epidemiological evidence into actionable population-level policy.
