Cortessis VK, et al. - This study was planned to estimate the association between use of an intrauterine device (IUD) and risk of cervical cancer by subjecting existing data to critical review, quantitative synthesis, and interpretation. Findings suggested an approximate one third less frequent invasive cervical cancer in women who had used an IUD. In populations with severely limited access to screening and concomitantly high cervical cancer incidence, this possible noncontraceptive benefit could be most beneficial.
