Abortion is the ending of pregnancy by removing a fetus or embryo from the womb before it can survive on its own. An abortion which occurs spontaneously is also known as a miscarriage. An abortion may be caused purposely and is then called an induced abortion, or less frequently, "induced miscarriage". The word abortion is often used to mean only induced abortions. A similar procedure after the fetus could potentially survive outside the womb is known as a "late termination of pregnancy".
Modern methods use medication or surgery for abortions. The drugs mifepristone and prostaglandin are as good as surgery during the first trimester.While medical methods may work in the second trimester,surgery has lower risk of side effects. Birth control, such as the pill or intrauterine devices, can be started at once after an abortion. When allowed by local law, abortion in the developed world is and has long been one of the safest procedures in medicine. Uncomplicated abortions do not cause any long term mental or physical problems.The World Health Organization recommends safe and legal abortions be available to all women. Every year unsafe abortions cause 47,000 deaths and 5 million hospital admissions.
