A skin tag is a small flap of tissue that hangs off the skin by a connecting stalk. Skin tags
are benign and are not dangerous. They are usually found on
the neck, chest, back, armpits, under the breasts, or in the groin area. Skin tags appear most often in women, especially with weight gain, and in elderly people. They do not cause any pain. However, they can become irritated if anything such as clothing or jewelry rubs on them.
