Risks & Consequences
The birth control pill is currently being used by more than 10 million women in the US.1 A number of physicians and researchers have claimed that the birth control pill (BCP) (also called an oral contraceptive) is actually an abortifacient. An abortifacient is a substance that causes an abortion, the death of the zygote, embryo or fetus after conception has occurred. Others do not believe the BCP is an abortifacient as noted in a 1998 publication authored by several physicians: Hormonal Contraceptives: Are they Abortifacients? 2
This booklet uses an easy-reading question and answer format to review the available evidence for determining how the BCP works. All of that evidence, whether microscopic, macroscopic, or immunological, indicates that the BCP sometimes causes an early abortion. When and how often this happens remain unknown. (more…)
What is an IUD?
An Intrauterine Device (IUD) is a small object that is placed inside a woman’s uterus (womb) for the purpose of preventing or interrupting pregnancy.
Currently, there are two kinds of IUDs available in the United States: the Copper-T IUD, made from plastic and copper, and the Intrauterine System IUS, a plastic device that releases hormones.
Is an IUD 100% effective?
No. Thecopper-T IUD has a clinical pregnancy rate of less than 1 per 100 women each year,1 and the IUS has a rate of 0.2 per 100 women each year.2 (more…)
1) How could the Pill cause breast cancer?
Two of the most important types of hormones that control reproduction are estrogens and progestins. Birth control pills are made from synthetic estrogens and/or progestins. Experiments have shown that these hormones cause women’s breast cells to divide more rapidly.1 Cells that divide more rapidly are more prone to develop into cancer cells.
2) What is the evidence that the Pill and breast cancer are connected?
In 2005, the World Health Organization classified oral contraceptives as a Group I carcinogen—the most dangerous classification known.2 Also, a comprehensive meta-analysis3 published in the Mayo Clinic Proceedings in October 2006 found that 21 out of 23 retrospective studies done since 1980 showed that women who took oral contraceptives prior to the birth of their first child sustained a 44% average increased risk of developing pre-menopausal breast cancer (see research chart inside). This risk rose to 52% for women who took the Pill for at least four years prior to the birth of their first child.
3) How serious of a problem is breast cancer?
Breast cancer is the most common cause of cancer death in the United States in women ages 20-59. About one in eight women will develop breast cancer at some time in her life. In the U.S. about 231,840 women are diagnosed annually, and over 40,200 die from this disease.4 More than one in five women who are diagnosed with breast cancer (i.e., 47,000 women annually) will develop it before menopause. This risk is increased even higher when combined with other breast cancer risk factors such as induced abortion, hormone treatment (such as estrogen supplementation), family history of breast cancer, and other factors.
4) Do some contraceptives cause more risk than others?
Yes. Research studies show that breast cancer risk is almost tripled for women who used Depo-Provera for 3 years or more before age 25.5
5) Are other types of cancer affected by oral contraceptive pills?
Oral contraceptives decrease the risk of ovarian and uterine cancer, while they increase the risk of liver, cervical and breast cancer.6 Since breast cancer is far more prevalent than the other three types of gynecological cancers, the Pill’s overall effect is detrimental to women.
6) Are there other risks from contraceptives?
Yes. Well known side effects of the Pill include an increased frequency of blood clots, high blood pressure, and heart attacks, as well as migraines, depression, loss of libido, and a variety of other disorders. Less well known is that oral contraceptives and injectable progestins (such as Depo-Provera) significantly increase the risk of contracting and transmitting HIV (the AIDS virus).7,8 In addition, medical studies strongly suggest that oral contraceptives work at times by causing an early abortion.9
7) How can I protect myself?
Many of the known risk factors for breast cancer can be avoided, such as hormone exposure (including hormonal contraceptives), induced abortion, heavy alcohol use, obesity, and radiation exposure. In addition, there is a significant reduction of risk with each child a woman bears. Every month of breastfeeding reduces breast cancer risk, as does bearing a child at a younger age. Some medications (e.g., raloxifene), which are taken after menopause to help strengthen bones, have been shown to markedly reduce the risk of post-menopausal breast cancer and should be considered by all women at high risk.10
8) If hormonal contraceptives are so dangerous, what options do couples have?
Natural Family Planning (NFP) methods are available and do not require chemicals or surgery and cause no increase in breast cancer risk. Not to be confused with the “rhythm method,” NFP is based primarily on observations of a woman’s cervical mucus. One of the largest research studies of NFP (involving 19,843 women and performed in India by the World Health Organization) showed a pregnancy rate of 0.2 pregnancies per 100 women yearly.11
Natural Family Planning methods have been used to diagnose and treat a variety of female reproductive disorders including infertility. Various medical problems (e.g., excessive menstrual cramping and bleeding), which are sometimes treated with contraceptive hormones, can often be treated by giving magnesium/calcium supplements and ibuprofen products after the onset of menses.
9) How can I find out more about breast cancer risk from the Pill?
Anyone may download the entire Mayo Clinic meta-analysis article by going to: www.MayoClinicProceedings.com and accessing the October 2006 archives. In addition, eleven of the seventeen chapters in the book Breast Cancer, Its Link to Abortion and the Birth Control Pill deal with cancer risks from birth control pills.6

What is “emergency contraception”?
“Emergency contraception” is the use of a drug or a device after intercourse to prevent pregnancy. Emergency contraception is promoted for use when a woman has been raped, when a couple has chosen to have intercourse without using any form of contra-ception, or when there is a suspected contraceptive failure. Types of emergency contraception include the Morning After Pill, the insertion of the copper-T Intrauterine Device (IUD) five to seven days after intercourse, or the use of the abortion drugs Danazol or Mifepristone (RU-486).
What is the “Morning After Pill”? (more…)
Oral birth control (and all other hormonal birth control—HBC) is typically used to prevent pregnancy, but is sometimes prescribed for other medical conditions. HBC causes many potential adverse effects: medical, social and spiritual. The vast majority of HBC prescriptions are given by physicians to healthy women, including adolescents with no known disease. These women are prescribed hormonal birth control for one reason—to prevent the completely normal condition of pregnancy.
Since all medications have potentially unwanted side effects, some of them serious, it is important that a physician weigh the risks and benefits when prescribing any medication. It follows that it is unethical to expose healthy women to health risks in order to prevent a normal condition. This is particularly true given the fact that there are alternative family planning methods, such as Natural Family Planning (NFP), which have no side effects when used correctly. (more…)
