While the majority of skin tags are simply destroyed, sometimes tissue is sent for microscopic exam by a health care specialist known as a pathologist, who will determine the exact diagnosis and determine whether an abnormality such as skin cancer is present. Irregular skin growths that are larger, bleed, or have an unusual presentation may require pathology examination to make sure there are no irregular cells or skin cancers.

But that doesn’t mean you should completely ignore skin tags. David Lorschter, MD, founder of Curology and a board-certified dermatologist in San Diego, notes there are exceptions.

Therefore, people with BCNS should have their skin tags biopsied and screened for cancer on a regular basis.
