Skin tags are not contagious.
More Info: Medically referred to as acrochordon, skin tags are simply common skin growths that often appear in mid-life and are generally harmless.
What Causes Skin Tags?
Skin tags are thought to appear due to the friction of skin rubbing on skin, which is why they are common in overweight people in areas where skin overlaps skin. They are also common in women with large breasts for the same reason. Hormones are also thought to play a factor in the appearance of skin tags as they are more prevalent in pregnant women.
Do Skin Tags Need to Be Treated?
Skin tags are generally benign and do not require treatment. It is not uncommon for small skin tags to fall off as a result of the same friction that caused them in the first place. In some instances, constant friction by clothing can cause skin tags to become irritated. If they become too uncomfortable then a doctor may suggest removal. Skin tag removal is a simple procedure in a doctor’s office requiring a small amount of local anesthetic and are either removed by freezing similar to a wart or by tying or cutting them off.
