There’s still a whole array of misbeliefs and mistruths about abortion which tend to arise during any debate about law or access. The idea of abortion being harmful or dangerous for women is a common one. Certainly this used to be the case, when abortion was largely self-induced or attempted, or carried out by untrained and unskilled operators, using whatever was to hand (in fact, some experts believe that protecting women from unscrupulous and dangerous backyard abortion providers was the reason abortion was criminalised in the first place). However, it’s no longer the situation here in Australia. The argument that abortion causes physical and/or mental harm to women is flatly contradicted by the evidence, and the longevity of this myth is more a result of successful anti-abortion propaganda than because it’s a fact.
In Australia, where abortions are performed by highly qualified health care professionals in very hygienic conditions, a pregnancy termination is one of the safest medical procedures and complications are rare .
Campaigns and organisations making claims about the serious harm caused by abortion distort research and often make false or intentionally misleading claims about abortion.
The three most often used myths in misinformation campaigns are that an abortion will affect a woman’s future fertility, that it causes breast cancer and that there are long-lasting psychological impacts of abortion .
Extensive evidence exists to show none of these are true.
The Royal College of Obstetricians and Gynaecologists (UK) and the Royal Australian and New Zealand College of Obstetricians and Gynaecologists state that “women who have an uncomplicated termination are not at an increased risk of being infertile in the future.” 
Organisations who reject a link between abortion and breast cancer include the World Health Organisation , the Australian Medical Association , the Royal College of Obstetricians and Gynaecologists , the Australian Cancer Council , the American Cancer Society , the Breast Cancer Network of Australia , the National Breast and Ovarian Cancer Centre (US) , and the National Cancer Institute (US) .
‘Post Abortion Syndrome’ is a term used by the anti-choice lobby but has not been widely accepted; the term is not recognised by the American Psychological Association or the American Psychiatric Association as a condition, nor is it found in the Diagnostic and Statistical Manual of Mental Disorders or the World Health Organisation’s International Classification of Diseases.
The American Psychological Association’s Taskforce on Mental Health and Abortion reviewed 20 years of research and studies into the psychological effects of abortion in 2008 and found that:
“[T]he prevalence of mental health problems observed among women in the United States who had a single, legal, first-trimester abortion for non-therapeutic reasons as consistent with normative rates of comparable mental health problems in the general population of women in the United States.”
