A skin tag is a benign growth of skin cells. They tend to form in areas where the skin creases, such as your neck, breasts, armpits and groin area. Close to half the population has skin tags but are more common among certain groups. Women, particularly during pregnancy, elderly, overweight and obese individuals are more prone to developing skin tags. Skin tags also tend to run in the family.
A skin tag is typically small, oval or round and hangs off the skin. Skin tags are not dangerous and are not a sign of skin cancer. Because they are benign there is no medical need to remove them.
If you, however, do not like the way your skin tags look or find them bothersome, you can have them removed. This can be done either by using a scalpel or scissors, freezing it or burning it off with electrosurgery.
