Dr. Lam performs careful mole removal based on the type of mole one has. If the mole is relatively flat and not very unsightly, he may elect to cauterize it off to minimize the cost and recovery compared to a surgically incised mole removal. However, if the mole is elevated and/or unsightly, he may excise the mole to ensure that it is properly eradicated since cautery can lead to recurrence. As seen in the Figure, elevated moles have a portion that remains under the skin that will lead to recurrence if not excised, so cauterization of raised moles most oftentimes fails.
Many people who develop skin tags simply choose to leave them alone. If, however, you find a skin tag unsightly or find that it’s becoming irritated by shaving or rubbing on clothing or jewelry, you can have it removed by a doctor. The two most common methods are cryotherapy, in which the tag is taken off using a freezing solution, or cauterization, in which the tag is burned off. There are also home kits available (similar to wart removal kits), but they may only be appropriate for certain small tags. Consult your healthcare provider for advice, especially if the tag is large (in which case a biopsy may be taken), or it is near your eye.
