Noncancerous, Precancerous and Cancerous Tumors

Skin tags, or acrochordons, are benign skin growths. They most often grow in areas where there are folds of skin such as under the arms, groin, neck, and eyelids. They range from skin-colored to brown in hue. Skin tags usually range in size from 2 to 5 millimeters, although the growths may be larger on long fleshy stalks. They do not cause symptoms but they may be painful if they are disturbed by clothing or jewelry. Skin tags may be removed surgically or with liquid nitrogen if they are bothersome.
