Update On How IUDs Can Help Prevent Cervical Cancer

Preventing Cervical Cancer With IUDs

Doctors have long been encouraging women to consider an IUD for contraception, to reduce heavy periods and provide a low dose hormonal option for menopausal hormonal therapy (MHT).

Research continues to show that this is a safe and effective option for women – even teenagers and women who have not had a baby. [1]

And, there is now a research to show that both the Copper IUD and Mirena IUD can be reliably used for contraception for longer than previously thought. The Copper IUD for 12 years,[2] instead of 10 years. And the Mirena IUD for up to 7 years, instead of 5 years. [3]

It is advisable, however, to discuss this with your doctor, as the companies that produce these devices have not yet changed their ‘product information’ advice to women.

At this stage, doctors are using this research to reassure women that they don’t need to panic about changing over their IUDs before the 10 and 5 mark…We have a bit of leeway. Phew!

Even more exciting news from the research world is the observation that women who used IUDs have a lower risk of suffering from cervical cancer.


Research – IUDs Can Help Prevent Cervical Cancer

Researchers at the University of Southern California have gathered information from 16 studies involving 12,000 women from across the world and found that women who have used IUDs had a 1/3 lower rate of cervical cancer compared to women who had never used an IUD.[4]

Scientists have two explanations for this amazing discovery of how IUDs can help prevent cervical cancer. One theory is that the precancerous lesions may be destroyed when the IUD is inserted and removed.[5]

The second theory is that the IUD stimulates the immune system to destroy the Human Papilloma Virus – the virus that damages cells eventually causing cancer. Wow!

Women with IUDs still need to have Cervical Screening tests every 5 years. Because you’re worth it!
