Intrauterine device (IUD) contraception
Use of some contraceptive intrauterine devices (IUD)* may be associated with a decreased risk of endometrial cancer. This association has been suggested for IUDs that release hormones and inert IUDs. No association has been seen for copper IUDs. Results are not consistent across different studies.
There are several possible ways that IUDs may decrease the risk of endometrial cancer. These include the local effects of the IUD on the endometrium as well as hormonal effects.
*An IUD is a contraceptive device that is placed in the womb (uterus). Two types of IUD are available in Australia: the hormonal IUD (MirenaTM) and the copper IUD. Inert IUDs are another form of device but are not available in Australia.
