Abortion is the deliberate termination of a human pregnancy, most often performed during the first 28 weeks. It is one of the most controversial issues today, with pro-abortionists believing parents should have the right to choose and anti-abortionists believing abortion is akin to murder. Reasons for abortion include unintended pregnancies, socio-economic factors, and medical issues of the fetus or mother. Abortions are performed through medication or surgery, with medication preferred up to 9 weeks and surgery after. While modern medical abortions are safe, unsafe abortions performed by unskilled people can result in death or disability.
