Some studies suggest a potential protective effect, possibly through local immune modulation, while others report no significant association. Evidence, however, remains scarce and inconsistent, particularly regarding long-term IUDs use. Our study aims to address these gaps by exploring the relationship between IUDs use and cervical cancer within the broader context of cervical cancer prevention. We conducted a narrative review by searching the PubMed, Scopus, LILACS, and Cochrane databases, utilizing a combination of text and Medical Subject Headings (MeSH) terms.
