Injuring yourself on purpose by making scratches or cuts on your body with a sharp object—enough to break the skin and make it bleed—is called cutting. Cutting is a type of self-injury, or SI. Cutting is more common among girls, but guys sometimes self-injure, too. People may cut themselves on their wrists, arms, legs, or bellies. Some people self-injure by burning their skin with the end of a cigarette or lighted match.
When cuts or burns heal, they often leave scars or marks. People who injure themselves usually hide the cuts and marks and sometimes no one else knows.
Self-injury is not new. It's also not a very common behavior. But lately people are talking about it more. As guys and girls hear about cutting, they may feel curious about it and why people do it. Because it seems a little bit forbidden, some younger teens may think that cutting might make them seem daring, grown up, or popular. (Opposing Viewpoints)
