It could lead to bleeding, infection or irritation
Cutting off a skin tag with scissors yourself can lead to infection or uncontrollable bleeding, which may require a trip to the ER. (You'd be surprised at how much a large skin tag can bleed if not cauterized or frozen by a professional.)

It is not clear exactly what causes skin tags, but it may happen when clusters of collagen and blood vessels become trapped inside thicker pieces of skin. As they are more common in skin creases or folds, they may be mainly caused by skin rubbing against skin.

Will Skin Tags Grow Back After Being Removed? Skin tags do not grow back after removal. If you develop other skin tags in the same place after removal, you may just be prone to having them in that area.

Friction can play a role in the development of skin tags. Commonly, they are located where skin rubs against skin or clothing. Frequently, they develop on the neck, underarms and eyelids, as well as within body folds, such as under the breasts or in the groin area.

The fastest way to remove them is through surgery or to freeze them off with liquid nitrogen. Some doctors might use an electric current or laser treatment to burn off the warts.

Treatment of genital warts is aimed at alleviation of symptoms and emotional distress. Most cases of genital warts will resolve spontaneously, usually within 12 months, if left untreated. There is no evidence that treating visible genital warts will prevent transmission of the virus.
