Do Birth Control Pills Cause Breast Cancer? The Latest Study

Last month, you might have seen headlines warning you that hormonal birth control increases risk for breast cancer. This news came from a study that examined the medical records of nearly 1.8 million Danish women — and the huge sample size lent heft to the findings, several of which stood in stark contradiction to commonly held beliefs about modern hormonal contraception.


Some types of hormonal contraception could increase breast cancer risk, while others may not. But the Pill also reduces risk for endometrial and ovarian cancers.


Birth control comes in two “flavors” — hormonal and nonhormonal. Hormonal contraception is among the most effective, and includes birth control pills, hormonal IUDs, the shot, the vaginal ring, the implant, and the patch. Nonhormonal contraception ranges from very effective, including surgical sterilization and the copper IUD, to the not-quite-as-effective, including condoms, diaphragms, and withdrawal. (With the exception of condoms, birth control does not provide protection against STDs.)

Hormonal contraception is one of the greatest achievements in the history of medicine, and offers those wishing to control their fertility an array of effective options. However, as with all effective medications, there is potential for side effects. And, because many forms of hormonal birth control contain types of estrogen, and exposure to estrogen is a risk factor for breast cancer, many people wonder if hormonal birth control might increase users’ chances of developing breast cancer later in life.

Most birth control pills contain a combination of two hormones: estrogen and progestin (synthetic progesterone). Other hormonal methods, such as the ring and the patch, also use combinations of these two hormones.

There are also pills that don’t contain estrogen, called POPs, or progestin-only pills — aka the “minipill.” Additionally, hormonal IUDs, the implant, and the shot are progestin-only methods.

What Previous Studies Have Shown

The connection between hormonal contraception and breast cancer is murky, because the association is difficult to study properly. There are so many different types of hormonal contraceptives, each with different dosages, different chemical formulations, and different ways of entering the body. We can’t tease these differences apart on the one hand, but make blanket statements about hormonal contraception as a whole on the other hand. But we can look at the available evidence and see where it points. Continue reading

Contraception in the Zombie Apocalypse

If you’ve watched a zombie movie with your friends, you’ve probably talked about what kinds of weapons you’d be packing in case of a zombie apocalypse. The Centers for Disease Control and Prevention even has a list of supplies you’ll need for a zombie preparedness kit, which includes smart choices like water, duct tape, and bleach. (I would add toilet paper to that list. How you’ll miss it when you’re on the run!) But how many of you have discussed birth control?


You’ve probably picked out which weapons to use during the zombie apocalypse. But have you chosen a birth control method?


Even if your greatest dream is to have a baby, you must admit that the zombie apocalypse is the worst time to be pregnant, give birth, and raise a child. Fleeing and hand-to-hand combat can be a drag while pregnant, and childbirth can kill you, especially without access to trained personnel or hygienic supplies. And if you do manage to birth a baby into this cruel new world, diapers can distract from more pressing duties, and the infant’s cries can attract undead attention.

When you’re in hardcore fight-or-flight mode, taking a pill at the same time every day might be difficult, and besides, a supply of pills can take up valuable backpack real estate. Plus, even if you find an abandoned pharmacy to raid, birth control pills and condoms come with expiration dates and can be affected by high temperatures. The same goes for contraceptive patches and rings. For these reasons, you need a contraceptive method that’s well suited to the zombie apocalypse. Besides abstinence, what are your options?

Let’s Talk Contraception: Birth Control and Travel — How to Stay on Schedule

beachIt’s summer and time for a much-needed vacation. But will crossing time zones require you to recalculate when you need to take your daily birth control pill? With a little pre-planning, you can enjoy a trip far away and still keep on schedule with your contraception.

If you use birth control pills, it’s important to take them on a regular schedule, usually one pill every 24 hours. But what do you do if your travel schedule has you in another time zone where your 9 p.m. dose is now due at 3 a.m.? You do have a few options.


Planning ahead can keep you on schedule with birth control and reduce stress while on vacation. Bon voyage!


One idea is to use a time zone calculator to keep taking your pill every 24 hours regardless of the local time. You may need to take it at 3 a.m. while on your trip, but when you return home, you will still be on your regular schedule of 9 p.m. A good way to keep on schedule this way is to have a clock or watch with you set to stay on your time zone at home so you are able to keep track of the correct time to take your pill. An alarm at the right time can be extremely helpful if you do have to take it in the middle of the night. Continue reading

Over 90 Percent of What Planned Parenthood Does, Part 21: Contraception

World Contraception DayWelcome to the latest installment of “Over 90 Percent of What Planned Parenthood Does,” a series on Planned Parenthood Advocates of Arizona’s blog that highlights Planned Parenthood’s diverse array of services — the ones Jon Kyl never knew about.

Birth control is about so much more than just one type of pill. First of all, there are dozens of varieties of the Pill, and beyond that even more types of contraception! With so many options available, you’re bound to find the birth control option that’s right for you, and Planned Parenthood can help you find it.

Birth Control Pills: The Pill is probably the first thing people think of when they think of birth control, and it’s no wonder: Since its introduction in 1960, it has become an iconic symbol of women’s liberation. Taken at the same time every day, the Pill is an incredibly effective form of birth control that works by suppressing ovulation. And there are many different types, from those that are specially designed to reduce the number of periods you have in a year, to progestin-only mini-pills, from name brand pills to generic pills, and more!

Vaginal Ring: Not everyone likes taking a daily pill; some people are naturally forgetful, while others have hectic schedules that don’t make it easy to dedicate a time of the day to pill-taking. That’s where contraceptives like NuvaRing come in: This flexible ring is inserted into the vagina, where it releases a low dose of daily hormones. Leave it in for three weeks, remove it for a week, and then start the cycle anew with a new ring!

Birth Control Patch: Ring not your thing? Maybe a patch is where it’s at. It works a lot like the ring, only instead of inserting it into your vagina, you pop the patch out of its wrapper and stick it to your skin, where it stays in place for a full week, releasing hormones all the while.

Eight Great Heat-Friendly Contraceptives

heat friendlyI don’t know if any of my fellow Arizonans have noticed, but it’s hot. It’s been hot. And all sources tell me that it’s likely to remain hot for a couple of months yet.

There are, of course, things we can do to make the heat more manageable for ourselves, such as drinking plenty of water and relegating intense outdoor activity to the early morning or late evening hours. There are also things we can do to help our contraceptives beat the heat if necessary, such as storing condoms or birth control pills away from extreme heat.

Still, some types of contraception require more intervention during the summer than do others. So — our top eight types of heat-friendly birth control!

Quick disclaimer: I made this list based on the single criterion that these methods are unlikely to be affected by the heat of an Arizona summer. When selecting a contraceptive method, there are loads of other factors to consider. So the methods on this list are not necessarily the most effective or appropriate methods for every person needing birth control.

8 Birth Control Vaginal Ring (NuvaRing)

  • Why It’s Heat Friendly: In terms of storage, it’s technically not; NuvaRing comes with the same temperature recommendations as oral contraceptive pills. However, since the ring is only inserted once per month, folks getting their rings one at a time don’t have to worry about longer-term storage.
  • Cons: In addition to the same risks and side effects of estrogen-containing contraceptives, NuvaRing isn’t the heat-friendliest choice for users getting more than one month at a time. Continue reading
