Abortion is the ending of pregnancy due to removing an embryo or fetus before it can survive outside the uterus. An abortion that occurs spontaneously is also known as a miscarriage. When deliberate steps are taken to end a pregnancy, it is called an induced abortion, or less frequently as an "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" or less accurately as a "late term abortion".
