A recent study has linked birth control pills and brain cancer. Obviously, this study is not going to damn birth control use. But it’s something all women should know about.

The study was released in late January 2015 in the British Journal of Clinical Pharmacology. The study found that women “who take the pill were twice as likely to develop a rare type of brain cancer called glioma.”

Young women between the ages of 15 and 49 were the subjects of the study. The following is the meaty part of the story:

“They then looked into how many of these women had an Rx for birth control pills, recording the type they took (either the estrogen-progestin ‘combo pill’ or the progestin-only ‘minipill’) and for how long. Finally, they compared them to a control group of glioma-free women in the same age range.

The results showed a 50 percent higher risk of glioma in women who took any pill type for any length of time. Scarily, the risk doubled among women who took progestin-only pills for at least five years.”

While on the surface that doesn’t sound too awesome, it shouldn’t concern women quite yet. More than a few doctors, including Alyssa Dweck, M.D., ob-gyn in Westchester, New York, are saying the study does show correlation, but it doesn’t show causation.

According to Women’s Health Magazine, the following are some of the things to keep in mind about the study’s results:

– “The rates may have been higher in Pill takers because women on oral contraceptives might be more likely to visit their doctor.”

– BMI may have played a role: Doctors often prescribe overweight women progestin-only pills, as they have fewer side effects, “such as blood clots.”

– Glioma is still extremely rare: around five in 100,000 women get it. If the rate is doubled, that means only 10 in 100,000 women will get it.

What do you think about this study? Do the results make you want to toss your pills?

The post Study Links Birth Control Pills and Brain Cancer…But Don’t Freak Out Yet appeared first on EcoSalon.

So, everyone knows that contraceptive pills can effectively prevent pregnancy. But did you know these pills also might enhance verbal and recognition memory?

We’ve all heard about the negative side effects of birth control pills. Women have experienced yucky side effects, such as mood swings, acne, and unwanted hair growth. (I must admit that I’m one of the lucky women. I have never experienced any of the formerly listed birth control pill side effects. Perhaps it’s because I’m taking one of the more modern pills that “exert anti-androgenic effects.” More on that…) But now, those negative side effects may become overshadowed by some possible positive side effects.

New research from the University of Salzberg (paired with research that emerged a few years ago) shows that oral contraceptive users “had larger volumes of gray matter” in their brain.

While the study from a few years ago didn’t account for androgenic activity, or control for age difference, the Salzberg study did:

“…the University of Salzberg enrolled 60 women into a new study. 20 of the participants were naturally cycling, i.e. not taking oral contraceptives (OCs), 18 were using OCs containing androgenic progestins, and 22 were taking OCs containing anti-androgenic progestins.”

Brain Research reported that after controlling for age, the study’s MRI scans showed that “women using anti-androgenic progestins had significantly larger gray matter volumes in several brain regions when compared with naturally cycling women.” The areas of the brain that were positively affected included the hippocampus (this area of the brain helps with learning and memory) and the fusiform face area (helps with facial recognition). The research also found that the longer the women used contraceptive pills, the more gray matter they developed. The women that took the androgenic progestins had smaller gray matter volumes. This number was compared with naturally cycling women.

The study also discovered that the women taking the anti-androgenic progestins performed significantly better in a facial recognition test than members of the other two groups in the test.

While this study isn’t perfect (the study was limited — small sample size, etc.) the study’s findings are still quite interesting.

Does this study change the way you think about modern contraceptive pills? Let us know in the comment section.
