IUD Lowers Cervical Cancer Risk

Sep 15, 2011
While in the past IUDs were often blamed for various health problems, the new research shows that it might actually give women some protection against cervical cancer.

The study conducted by researchers at the Catalan Institute of Oncology, Spain, on 20,000 women, revealed that women using IUD were not more likely to have HPV (human papillomavirus) that is linked to cervical cancer and that their risk of developing cervical cancer was cut by half.

The research team has analyzed studies on cervical cancer in 8 countries and surveys on HPV prevalence around the world. The findings showed that IUD use does not increase the risk of getting HPV infection, but it was linked to lower risk of developing cervical cancer by 44 to 54 percent. The risk of cervical cancer reduced by half during the first year of use and the effect continued for more than 10 years.

Experts note that IUDs themselves do not stop the HPV infection.

Specialists suggest that the possible explanation for such protection may be the process of inserting ad removing the IUD that may kill pre-cancerous cells. The other version is that IUDs contribute to a sort of inflammation that brings in prolonged immune response and it stops HPV from progressing.

Other studies have found that IUDS may protect women from endometrial cancer.
