Intrauterine device use linked to 30% lower risk of cervical cancer

  • Researchers at the University of South California found'very strong evidence the IUD coil protects women against cervical cancer and found no other reason for the association

"At this point we can only hypothesize about how an IUD might decrease cervical cancer risk", said lead study author Victoria Cortessis of the University of Southern California in Los Angeles.

The report was published online November 7 in the journal Obstetrics & Gynecology.

To explore the theory, the team scoured medical literature for research that measured IUD use and cases of cervical cancer. In addition, complex tests that require many sampling instruments, need of trained pathologists & cytotechnicians, and need for continuous monitoring to obtain high-quality results are all major factors restraining the growth of the global cervical cancer therapies and diagnostics market.

IUD birth control devices can reduce women's risk of developing cervical cancer by about a third, possibly because it promotes an immune response the kills the human papilloma virus (HPV), the virus that causes the disease. Cervical cancer is treatable and associated with long survival when detected early. However, the pooled analysis is only clinically useful if the underlying studies are high quality.

The incidence of cancer of the cervix is increasing in the world.

Women who developed cervical cancer were matched for a number of factors - such as age, ethnicity and sexual history - with a control group of women who did not develop it. This is significant primarily because it was the first study to combine data from multiple studies on IUDs and cervical cancer.

A total of 16 studies had a strong enough design to be included in the pooled analysis.

However, Dr Pradeep Tanwar, who investigates gynaecological cancers, said the study was limiting.

But they also noted that, because contributing studies were completed before an HPV vaccine was available, "the magnitude of this association may be most relevant to populations in which women 30 years of age and older remain largely unvaccinated". As HPV causes the majority of cases of cervical cancer in the United Kingdom, the NHS has offered the HPV vaccine to girls aged 12 to 18 since 2008. Most of the time, HPV infections go away on their own, but when they do not, they can lead to genital warts and various kinds of cancer, including but not limited to cancer of the vulva, vagina, penis, anus, or throat - and, of course, the cervix. The protective effect did not appear to be due to confounding by risk factors or publication bias, according to the authors.

Finally, Lichtenfeld said he's concerned that people might use these results as an excuse to forgo regular Pap testing or not get their children vaccinated against HPV.

The ParaGuard also works as an emergency birth control if inserted within 5 days after unprotected sex it is 99.9% effective.

Alright, so for those out there who are interested in getting an IUD or just want more information on the subject the Planned Parenthood website has concise information with all the details you need.

An IUD will also not protect you against sexually transmitted infections.
