To demonstrate this, we will conduct an open label 1:1 cluster randomized controlled trial. As the gender of the physician and his ability to carry out pap-tests is associated to the rate of his listed screened female patients, randomization will be stratified on these two variables. The 24 participating physicians (12 in each study arm) will enroll 2000 unscreened female patients. The study population will be all the social security insured unscreened listed women aged from 30 to 65 years of the participating physicians. As the specificity of the HPV-test to screen for CC is insufficient before the age of 30, woman between 25 and 29 years of age will not be part of the study.
