Since ancient times abortions, have been done using herbal medicines, sharp tools, with force, or through other traditional methods. Abortion laws and cultural or religious views of abortions are different around the world. In some areas abortion is legal only in special cases such as rape, problems with the fetus, poverty, risk to a woman's health, or incest. In many places there is much debate over the moral, ethical, and legal issues of abortion. Those who are against abortion often maintain that an embryo or fetus is a human with a right to life and may compare it to murder. Those who favor the legality of abortion often hold that a woman has a right to make decisions about her own body.
