I don’t believe they do any cutting. This though is essentially back alley abortions made legal. They just replaced the clothes hanger for a vacuum pump. Not without complications either way.
What happens if they cannot suck part of the baby out? What can they do? What if they misjudge the age of the baby and it is, for example, over 6 months along, and create a mess inside the womb of the girl/woman? These things are possible with people without the proper medical training.
