Medical Studies

There have been many studies done throughout the world on abortion-related concerns. As with any medical issue, one should know all the potential risks and side effects in order to make an informed decision.  Abortion is no different.

Out of the 108 studies, 79 (nearly 3 in 4) found an increased risk between induced abortion and the later development of breast cancer.


According to the American Association of Pro-Life Obstetricians and Gynecologists (AAPLOG), having abortions leads to an increased risk of pre-term birth, mental health problems, breast cancer, and death.

Abortion and Pre-term Birth

139 statistically significant studies spanning 40 years demonstrate a statistically significantly associated increased risk for preterm birth with elective abortion.

  • One abortion increases a woman’s risk of preterm birth by 30%.
  • Two or more abortions increases a woman’s risk of preterm birth by 50-70%.
  • BUT, two or more abortions dramatically increases the risk of VERY PRETERM BIRTH (1500grams, or less than 28 weeks gestation) by greater than 200%.

Abortion and Mental Health

Accumulating studies from around the world continue to show an increased risk of mental health problems for women who abort as compared with women who carry a pregnancy and give birth. One of the most thorough analyses of the literature [Coleman PK. Abortion and mental health: quantitative synthesis and analysis of research published 1995–2009 The British Journal of Psychiatry (2011) 199, 180–186. doi: 10.1192/bjp.bp.110.077230] revealed:

  1. Overall, women with an abortion history experience an 81% increased risk for mental health problems. The results showed that the level of increased risk associated with abortion varies from 34% to 230% depending on the nature of the outcome. Separate effects were calculated based on the type of mental health outcome with the results revealing the following: the increased risk for anxiety disorders was 34%; for depression it was 37%; for alcohol use/abuse it was 110%, for marijuana use/abuse it was 220%, and for suicide behaviors it was 155%.
  2. When compared to unintended pregnancy delivered women had a 55% increased risk of experiencing any mental health problem.
  3. Finally, nearly 10% of the incidence of all mental health problems was shown to be directly attributable to abortion.

Abortion and Breast Cancer

Childbearing history, especially age at completion of a first term pregnancy and exposure to estrogen are established risk factors for breast cancer. Research indicates that one action could increase the risk of breast cancer 30%-79%. 

Currently, there are more than 108 worldwide studies published on abortion and breast cancer.  Out of the 108 studies, 79 (nearly 3 in 4) found an increased risk between induced abortion and the later development of breast cancer. 

  • 53 studies found a strong link between abortion and breast cancer
  • 26 studies found a small link
  • 29 found no link

A "link” is properly termed a “positive association” or “increased risk” or “risk factor.” It does not define a cause and effect relationship between the risk factor and getting the disease. It’s important to note that having a risk factor does not mean you will definitely come down with a particular condition, just that you are at an increased risk of developing the disease.

Abortion increases the risk of premenopausal breast cancer by arresting the developing breast tissue in a state susceptible to other environmental carcinogens. Abortion of a first pregnancy with delay in subsequent term pregnancy causes the breast lobular cells to be arrested in a proliferating state, without the subsequent maturation to lactation that occurs at the end of a pregnancy prior to birth. The later in pregnancy the abortion occurs, the higher the risk. The more abortions, the higher the risk.

Abortion and Death

Maternal mortality is an awful tragedy. But sadly, that tragedy is being exploited by the proponents of worldwide abortion legalization under the myth of “safe” abortion. Abortion is not “safe” for the mother, regardless of the conditions under which it is performed because it increases the mother's risk of suicide, depression, substance abuse, preterm birth in subsequent pregnancies and can increase her risk of breast cancer. But the terms”safe” and “unsafe” abortion are even more twisted, as they are actually legal not medical terms.
