If someone continues to develop skin tags repetitively in the same spot after removal, he is simply more prone to forming them than others, or the skin is rubbing too often. Skin tags often appear in places where the skin rubs excessively, such as the groin, according to MedicineNet.com.
Skin tags are very rarely malignant and do not require removal, states MedicineNet.com. Some people who continually develop skin tags schedule periodic removal of the tags due to cosmetic concerns. Most medical insurance companies do not cover skin tag removal unless it's medically necessary or highly symptomatic. If a bump arises that looks like a skin tag, but it bleeds, grows large or has multiple colors, the bump should be checked by a physician as soon as possible.
