A new study published in the Journal Obstetrics & Gynecology has found that the Mirena intrauterine device (IUD) could lead to an increased risk of developing breast cancer. Mirena is a birth control device that emits an artificial hormone called levonorgestrel, which is intended to regulate ovulation.
The study involved more than 93,000 Finnish women aged 30 to 49, all of whom were using the hormone-releasing IUD. Women using the Mirena IUD were 19% more likely to develop breast cancer than women who did not use the device. Women aged 45 to 49 were at a particularly increased risk.
Thousands of women have issued Mirena IUD complaints to the Food and Drug Administration alleging that the device caused severe side effects. Some women suffer from tissue damage, bleeding, severe discomfort and ectopic pregnancy when the device dislodges and travels through the uterus.
