IUDs Might Significantly Reduce the Cervical Cancer Risk

This contraception can cut cancer risk by 33%

HPV infections have been linked to cervical cancer in several studies before and protection against these viruses can provide protection against cervical cancer.

She said that it could be that these IUDs trigger an immune response that ends up strengthening the body to fight a viral infection caused by human papillomavirus (HPV).

How so? It analyzed data from 16 high-quality observational studies involving more than 12,000 women worldwide.

She said it would add to the benefits of using an IUD and would be especially helpful for women who may not have access to HPV vaccines. "It was not subtle at all", says the study's lead author, Victoria Cortessis, PhD, associate professor of clinical preventive medicine at the Keck School. "That means for decades to come this epidemic of cervical cancer is with us".

Scientists plan to continue their research to understand how IUDs can be used as protection against the illness. "It looks real. It smells real, but to be really convinced, we need to go back and do studies to find a mechanism". Researchers at Baylor College of Medicine said the damage appeared even in patients who experienced mild symptoms or no symptoms at all.

Some believe the placement of the IUD causes an immune response in the cervix that helps the body ward off an HPV infection that could one day lead to cervical cancer.

Walt Disney Co (DIS) Shares Surge Despite Weak Earnings
Current trade price levels places DIS's stock about -12.85% away from the 52-week high and closed 9.85% away from the 52-week low. A number of analysts offered their Estimated Earnings analysis for The Walt Disney Company ( DIS ) for the current quarter.

A promising study about the third cancer most common among women.

"A staggering number of women in the developing world are on the verge of entering the age range where the risk for cervical cancer is the highest - the 30s to the 60s", she revealed in the report.

"This is just one more reason potentially to help us recommend a great contraceptive method to women", said Rabin, co-chief of the division of ambulatory care with Women's Health Programs-PCAP Services at Northwell Health in New Hyde Park, N.Y.

But Cortessis said her team took into account individual cervical cancer risk factors such as prior pregnancy, HPV status and number of sexual partners, and found that each of these factors did not affect their bottom-line findings. And despite the analysis of confounding variables and robust size of the review, there will still be concern about lingering confounding variables until there is a clinical study, he said. Cervical cancer is usually a slow developing type of cancer which may or may not exhibit symptoms of the disease.

The analysis is "fascinating", and the potential explanation for why an IUD might reduce cervical cancer risk "really does make sense", said women's health specialist Dr. Jill Rabin.

"The results of our study are very exciting".
