What is the name for one who practices self mutilation?

Terms that people most widely used are 'self-harmer' or just 'Cutter'. But it is so discouraged to use these terms. People argue that it is not right because it is labelling someone. It makes it as if that is their life when it is just, what many people, may call it a 'symptom', that shows there is something distressing that person. Hope this helps more!
