The mechanisms by which sex steroid hormones affect the multi-stage natural history of human papillomavirus (HPV) infection and cervical carcinogenesis are still unclear, with no consistent evidence in support of a single biological hypothesis. Understanding the means by which hormonal contraception affects HPV infection and cervical cancer risk may provide critical information to guide future secondary interventions for cancer prevention.Keywords: hormones, human papillomavirus, cervical cancer
