[Hormonal contraception as a risk factor for developing cervical cancer: biological, epidemiological and immunological evidence].

BACKGROUND

Cervical cancer has been extensively studied, as well as the various risk factors for that cancer. One such factor is the prolonged use of hormonal contraceptives.

OBJECTIVE

To report the biological, immunological and epidemiological findings arising from the use of oral contraceptives and their relation to cervical cancer.

MATERIAL AND

METHODS

Retrospective study based on information published in national and international literature.

CONCLUSIONS

Controversy persists between the epidemiological data and experimental biological association between hormonal contraceptives and cancer induced by HPV. It is important to consider the biological findings because in Mexico the use of hormonal contraceptives is very broad and the number of cases of cervical cancer and only extensive epidemiological studies will clarify this controversy.
