Benign skin tags are fairly common, harmless and do not usually require medical attention, but you may find them unattractive and choose to have them removed. Once formed, skin tags rarely fall off on their own, so you’ll need to talk to your doctor if you want treatment.
Definition
A skin tag, also called an acrochordon, is a small growth connected to the skin by a narrow stalk. By definition, skin tags are benign, so they’re typically referred to as that rather than “benign skin tags.” They occur anywhere on the body but are most common on the neck, armpits, chest, back, groin and under the breasts. Skin tags are usually flesh-colored but may be a little darker and are found in about 25 percent of the population, according to the American Family Physician.
Causes
Skin tags are thought to be caused by friction, such as when skin rubs together in skin creases. People who are overweight or diabetic are at a higher risk of developing skin tags. They’re also more commonly found in women, those who are overweight and in the middle-aged or elderly.
Symptoms
Skin tags normally don’t have physical symptoms other than their appearance. They can cause discomfort, or become irritating, if they occur in an area where they’re rubbed by clothing or other items.
Diagnosis
Special tests are not required to make a diagnosis; a health professional just needs to assess the appearance of the tags. But if their size, shape or color casts any doubt, your physician may request a biopsy to be certain they're benign.
Treatment
Skin tags do not need to be treated unless you want them removed because of their appearance or irritation. Your physician can remove the skin tags by cutting them off, freezing them, called cryotherapy, or by burning them with an electric current, called electrosurgery, according to the Cleveland Clinic. Small skin tags usually do not need anesthesia.
Considerations
Just like any mole or skin growth, if the appearance of a skin tag changes, you should consult a physician. If skin tags are accidentally cut or pulled off, they may bleed excessively. Apply constant pressure directly to the spot until the bleeding stops.
