Abstract |
Combined estrogen-progestogens used in oral contraceptives and hormonal therapy have many similarities. Consequently, there is a possibility that women who use both during their lifetime may experience risks that are greater than women who use either contraceptives or hormonal therapy but not both. The conclusion that the increased risk for breast cancer returns to background levels 10 years after cessation of use of contraceptives may therefore not apply to women who have begun to use hormonal therapy. Further epidemiological studies of women who have used both contraceptives and hormonal therapy are necessary. Oral contraceptives can increase the risk for cervical cancer in women who have a human papillomavirus infection. Women who use this form of contraception over long periods of time should be encouraged to participate in cervical cancer screening programmes. |
