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

STD Awareness: Do IUDs and Implants Prevent STDs?

Highly effective birth control methods, namely intrauterine devices (IUDs) and implants, have received a lot of well-deserved attention in recent years. They are as effective at preventing pregnancy as permanent sterilization, but can be stopped at any time, and can last from three to 12 years. They are the contraceptive of choice for female family-planning providers, who should know a thing or two about choosing an optimal birth control method. They are fantastic options for teenagers and others hoping to delay pregnancy for at least a few years. And the best news is that, for now anyway, these pricey birth control methods are still available at no cost to Americans covered by Medicaid or health insurance.


For the best protection against unintended pregnancy and STDs, combine condoms with IUDs or contraceptive implants.


If IUDs and implants prevented sexually transmitted diseases (STDs), they would pretty much be perfect — but, alas, like most forms of birth control, they don’t protect you from viruses, bacteria, and other bugs that can be passed from person to person through sex. To reduce their risk for STD exposure, sexually active people must employ other strategies, including (1) being in a mutually monogamous relationship with a person who does not have STDs; (2) being vaccinated before becoming sexually active to receive protection from hepatitis B virus and human papillomavirus (HPV), two sexually transmitted viruses; and, last but definitely not least, (3) condoms, condoms, condoms!

A study published this month looked at college students using IUDs and implants and found that most of them didn’t use condoms the last time they had vaginal sex — 57 percent of women who were not using IUDs or implants used a condom, compared to only 24 percent of women who were using IUDs or implants. That’s not too surprising if pregnancy prevention were the only concern, but condoms are an important addition for anyone seeking to reduce their STD risk. Continue reading

IUDs and Implants: It’s Not Too Late for LARCs

Access to contraception is coming under attack, and reproductive-health advocates are scrambling to find ways to protect it. In December, Obama did what he could to protect Planned Parenthood from losing its ability to serve Medicaid patients. In New York, the state’s attorney general has moved to ensure that New Yorkers will continue to receive no-copay birth control as part of their insurance benefits, and Massachusetts moved to defend Medicaid patients’ right to use Planned Parenthood’s services in the event of federal interference. And, across the country, people at risk for unintended pregnancy are clamoring for highly effective, long-term birth control to see them through the next four tumultuous years.


IUDs and implants can help you and your uterus make it through the Trump administration.


Tom Price, who was confirmed as secretary of health and human services last month, represents the most immediate threat to our birth-control access. As HHS secretary, Price has the power to declare that contraception is not a “preventive” service insurers must make available to their customers with no copay. In one fell swoop, Price could undo the enormous progress the Obama administration made in expanding access not just to all forms of contraception, but to highly effective forms of contraception that had for so long been out of reach to so many.

Before the Affordable Care Act, long-acting reversible contraception (LARC) methods like IUDs and implants were known to be highly effective — not just cost-effective, but also simply the most effective in terms of preventing pregnancy. However, the high upfront costs closed the door to many potential users. Let’s do some quick-and-dirty math: A copper IUD could set you back anywhere from $500 to $932, but it lasts for 12 years. That means it costs $3.50 to $6.50 per month, compared to the Pill, which can cost $10 to $50 a month out of pocket. Clearly, the IUD makes the most financial sense, but for many of us, a medical bill charging upward of $500 doesn’t fit into our budgets. Better to rely on methods like the Pill, which cost more over time, but aren’t as hard on the wallet of someone living paycheck to paycheck or on an otherwise tight budget. Continue reading

Let’s Talk Contraception: How Effective Is My Birth Control?

According to the Guttmacher Institute, 62 percent of women of child-bearing age (roughly 15 to 44 years of age) currently use a contraceptive method. Most contraceptive users are married and on average would like to have two children. This means that a woman might be using a contraceptive method for more than 30 years.

Studies have calculated that if a sexually active woman is not using any contraceptive method, over the course of a year she has an 85 percent chance of becoming pregnant. Using contraceptives greatly decreases this chance, but there are still some possibilities that her contraceptive method could fail to prevent pregnancy.


To maximize your contraception’s effectiveness, use it as correctly and consistently as possible.


When choosing a contraceptive method, you might want to use the safest and most reliable method available. How likely is it that your choice could fail? With the many types of birth control at your disposal, how do you know which is most effective? And why, with even the most effective contraception around, do women still have unintended pregnancies?

If we rank birth control methods according to most effective to the least effective, how do they compare? How is effectiveness measured?  Continue reading

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
