How serious is a skin tag?

Skin tags. Skin tags are small extentions of skin, that occur in areas of friction, like groin folds, under arms, under the breasts of women, and even on the eyelids. They have a family basis, and are never dangerous. Some people have dozens, and occasionally one or several get irritated. They can be removed quickly and easily by a dermatologist, but may not be covered by health insurance.
Not serious. It is not serious. It can be removed if it is irritated or bleeding.
