As the outrage continues over the Supreme Court’s decision to put Americans’ religious liberty ahead of their right to free contraception, a new study from Finland shows that a type of IUD has been linked to an increase incidence of breast cancer.
CNN is reporting that, according to a study published in the journal of Obstetrics and Gynecology, the levonorgestrel-releasing intrauterine system (LNG-IUS) or progesterone-releasing IUD, may be associated with a higher than expected incidence of breast cancer.
What caught my eye, though, is that levonorgestrel, a hormone that regulates ovulation, is also the used in the Plan B contraceptive, better known as the morning after pill. Millions of American women are now going to receive the IUD and Plan B free, thanks to Obamacare, and most of them will have no idea they could be increasing their risk of breast cancer.
CNN doesn’t delve into that possibility, but here’s what the Polycarp Institute, a Catholic research think tank, has to say about Plan B and breast cancer:
Does Plan B cause breast cancer?
Ironically, this question has never been asked. Theoretically, this is certainly possible especially in women who use Plan B often as a method of “birth control.” How could this be? Plan B is composed of the hormone named levonorgestrel, which is a potent progestin which is also found in some of today’s birth control pills. Birth control pills have been declared a Class 1 carcinogen (ie, the most dangerous type) by the World Health Association in June, 2005. In addition, the most recent meta-analysis published in the Mayo Clinic Proceedings (October, 2006) noted that taking the birth control pill before pregnancy results in a 44% increased risk of developing breast cancer prior to age 50. Finally, levonorgestrel’s progestin “cousin” (ie, Depo Provera) has been noted to increase breast cancer by 190% in women who take 12 shots prior to age 25 (JAMA, 1995: 799-804). These data theoretically implicate Plan B if taken often enough. In addition, when a woman takes Plan B she ingests 1.5 mg of levonorgestrel within a twelve hour period of time which is nearly equivalent to the amount of progestin contained in an entire month’s worth of some of today’s low dose birth control pills (ie, 1.925 mg).
Not to get off topic, but it’s also worth mentioning that while the mainstream media is dutifully regurgitating the “fact” that Plan B is not abortifacient, the scientists at Polycarp feel differently:
Is Plan B a contraceptive or an abortifacient?
The truth is, no one knows for sure but it probably does work by causing early abortion at least part of the time. The 2010 Physician’s Desk Reference notes that Plan B “may inhibit implantation by altering the endometrium.” In addition, Croxatto et al noted that Plan B only fully stops ovulation 12% of the time when given within two days of ovulation (Contraception, 2004: 442-450). This would point to an abortifacient method of action since ovulation and consequent fertilization would likely be occurring much of the time, yet visible pregnancy is usually absent. Finally, Mikolajczyk and Stanford showed via a sophisticated mathematical model, that if Plan B really were to be 75% effective, it likely would be working as an abortifacient at least some of the time (Fertility and Sterility, 2007: 565-570). In the future, researchers might be able to “prove” if and how often Plan B is an abortifacient by employing the use of a very early pregnancy tests which turn positive within the first 7 days of pregnancy (eg, EPF: Early Pregnancy Factor).
As CNN notes, most women use the progesterone-releasing IUD to treat heavy periods. That’s also the reason millions of women start taking birth control pills as teenagers. Dr. Anne Nolte, a pro-life, pro-woman obstetrician and gynecologist, points out that this is bad medicine. Instead of trying to get to the source of the problem and fix it, hormonal contraceptives like the Pill and some IUDs just shut down the system and restart it artificially. This gives doctors an easy way out and sometimes, it gives women breast cancer.
