Small tags of excess skin can appear anywhere on the body but are most frequently found on the neck, in the armpit, under the breasts, and in the groin creases. They may become irritated with friction particularly in overweight people. When the skin is confused as to which direction it should grow, it simply grows out and skin tags appear. Medically, these tags are known as acrochordons. Avoiding excessive weight gain and constrictive clothing which causes friction, helps prevent skin tags from appearing. Skin tags can be easily removed by a dermatologist.
