Rural Senegalese women have limited access to cancer screening services, leading to late-stage diagnoses and poor treatment outcomes. A mixed-methods approach including baseline surveys, follow-up interviews, and health record reviews was employed to assess programme impact. Early detection rates increased from 20% pre-screening to over 45% post-screening, with a significant reduction in advanced-stage cancer cases (p < 0.001). Community-based screening programmes significantly improved early detection and treatment outcomes for rural Senegalese women. Further expansion of similar programmes is recommended to increase access and reduce late-stage diagnoses. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
