Mirena IUD Side Effects May Increase Risk of Breast Cancer: Study

New research suggests that side effects of IUD birth control implants, such as Mirena and Skyla, which release the progestin levonorgestrel, may increase the risk of breast cancer.

Mirena and Skyla are intrauterine devices (IUD), sometimes referred to as intrauterine systems (IUS), which are implanted into the uterus to provide long-term birth control protection against pregnancy.

In a study published ahead of print in the medical journal Obstetrics & Gynecology, Finnish researchers report that while levonorgestrel-releasing IUDs do appear to protect against some types of malformations and other cancers, women who receive the implants to treat heavy periods may face a greater risk of breast cancer.

Researchers looked at data on women from ages 30 to 49, who used levonorgestrel-releasing intrauterine systems (LNG-IUS) from 1994 to 2007

for menorrhagia, which involves an abnormally heavy and prolonged menstrual period at regular intervals. The data was collected from the National Reimbursement Registry and the Finnish Cancer Registry.

In the U.S., Bayer sells both of the LNG-IUS systems on the market, the Mirena IUD and the Skyla IUD. Levonorgestrel is a second-generation progestin commonly used in birth control products, including many birth control pills.

The study found 2,781 cases of cancer among women using a levonorgestrel IUD. For most cases, the rate of cancer dropped significantly when a woman used a LNG-IUS. Cases of endometrial adenocarcinoma were cut in half, and there were only 60% of the expected cases of ovarian cancer. Pancreatic cancer rates were also cut in half by women using a LNG-IUS, and rates of lung cancer dropped 32%.

However, researchers saw a nearly 20% increase in the risk of breast cancer with levonorgestrel IUDs. Based on the rate among the general population, researchers expected to find 1,292 breast cancer cases, instead they found 1,542.

“The levonorgestrel-releasing intrauterine system may have a protective effect against endometrial malignant transformation. Using the levonorgestrel-releasing intrauterine system for treatment of menorrhagia during reproductive years was associated with a lower incidence of endometrial, ovarian, pancreatic, and lung cancers than expected,” the researchers concluded. “Levonorgestrel-releasing intrauterine system use was associated with a higher than expected incidence of breast cancer.”

Mirena IUD Problems

Mirena is the best selling IUD in the United States. However, only a few variations of the long-term birth control implants are on the market, including Mirena and Skyla, as well as the ParaGard, which does not release levonorgestrel.

Bayer currently faces several thousand Mirena lawsuits, involving allegations that the drug maker failed to adequately warn about potential side effects of the IUD birth control. Most of the cases involve women who suffered severe internal injuries after Mirena IUD migrated out of place, resulting in perforations of the uterus and other complications.

Bayer has maintained that it intends to defend the migration injury cases, arguing that information about the risk of perforation was included on the warnings provided with the IUD. However, plaintiffs in that litigation maintain that the previous warnings were vague and misleading, suggesting that the risk of injury only exists at the time of insertion. Most of the complaints involve women who found that the Mirena migrated spontaneously, often long after the IUD was successfully placed in the uterus.

In the federal court system and New Jersey state court, coordinated proceedings have been established, centralizing the cases before one judge to avoid conflicting pretrial rulings, duplicative discovery and to serve the convenience of the parties, witnesses and the courts.

Given the similar factual allegations raised in the cases, a series of Mirena bellwether trials are expected to begin in the second half of 2015, designed to help the parties gauge how juries may respond to certain evidence and testimony that is likely to be repeated throughout the litigation.

If Bayer continues to refuse to make any Mirena settlement offers following a series of bellwether trials in the MDL, the drug maker could face hundreds of individual trials throughout the United States.

    I had the Mirena IUD inserted in 2012, then a new one, as recommended, in 2019. At 48 years old, I was diagnosed with triple positive invasive ductal carcinoma in my left breast on November 6, 2020. My doctors immediately scheduled the removal of my Mirena IUD. I was told that estrogen is like fertilizer to breast cancer cells. Why, after 10 years, wasn't I told this before?

My cancer feeds off of the same hormones the Mirena secretes over time. I am convinced the Mirena gave me terminal breast cancer, especially after reading so many other young women’s stories, and reading some of the studies.

I strongly believe my BC is down to marina coil consultants have said to have the coil removed and to have different tumours I must have faulty gene but no family history of BC just waiting for results of gene test I think breast care team have a idea that this is causing BC we all need this proving. I not looking for someone to blame but too many women have no family history low risk of BC but all have coil in common I think there's a link iam only 34 yrs old grade 3 tumours something needs to be done for future women so they don't have to go though what we all have to. wishing everyone the best of luck with beating this disease

    I have had the same experience as so many listed above...no family history, clear mammograms, and then aches and pains in breast which ended up being cancer. Truly believe that it was from the estrogen in the Mirena!

I went to the doctor and my doctor sent me to the breast center. I received an ultrasound then a biopsy because the ultrasound looked suspicious... well the biopsy was positive,( estrogen positive receptors )! No history of breast cancer in my family!!!

Immediately after having the Mirena removed I began having breast pain, almost similar to when I was breast feeding and weening.. I thought it was a side effect from going off the Mirena but now two months later I am having extreme constant pain in my right breast. It feels heavy and painful all day now, just in one breast. I have no history of breat cancer but am terrified that it may be cancer and a side effect from Mirena. My husband is urging me to go to the doctor but my insurance is awful and will cost us $8k out of pocket to have the necessary testing done. I am so sorry to read about the pain you all are going through... I am wondering what your initial symptoms were and if I should go to the doctor and get tested? My prayers and love to you all.

Let’s back up....in February 2017 I went in for my annual mammogram and my results came back normal. Well, in March 2017 I had the Mirena inserted because of heavy menstrual flow. In July I did a self breast exam on my right breast because I had sharp pains in my upper breast area. During my exam I noticed a lump in my breast and it was something about it that made me call my primary care physician the next morning. I went to see my PCP and he didn’t think it was anything to be concerned about since my mammogram in Feb 2017 was normal but he wanted to be on the safe side and sent in a referral to the Breast Center. I went to the Breast Center a few days later after seeing my PCP and they performed a mammogram and an ultrasound of my breast. The physician took me in room and told me that my results looked suspicious and that I need to have a biopsy done. I went in the following week for my biopsy and a few days later, I received a call that it was cancer. Bayer need to removed this device off the market. Obviously, it is the cause of breast cancer for so many women! My God read the comments!!!

    I had the Mirena for excessive bleeding at age 47. Four years later I was diagnosed with estrogen receptive breast cancer that was growing 10 times faster than the average cancer. Sure wish someone would have told me of the 20% increase in risk because my mother died of breast cancer. I even asked my doctor if it would make a difference in my chances. She said no!
