Breast Cancer-Related Approach for Increasing Cervical Cancer Screening

The primary objective of this clinical trial is to assess cervical cancer screening participation among under-screened women invited through organized breast cancer screening programs in Switzerland. This randomized trial will compare three arms: 1. Intervention group 1: Sensitization to Cervical Cancer (CC) screening Women will receive an awareness letter explaining the importance of cervical cancer screening, the Swiss recommendations and an invitation to schedule an appointment. 2. Intervention group 2: Home-based Human papillomavirus infection (HPV) self-sampling Women will receive a free-of-charge vaginal self-sampling kit for HPV infection 3. Observational control group Women selected in the control arm will only be recruited one year following the screening of those in the intervention arm (T0+1), as to not influence Cervical Cancer Screening (CCS) behavior during this period by being reminded of screening recommendations.
