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.
Although skin tags are primarily a cosmetic problem, that doesn’t mean they’re not significant enough to consult a doctor. For starters, they can still bleed when they come off, so dermatologists stress never trying to cut or pull off a skin tag on your own. One theory on skin tag removal is that tying it off with dental floss will remove it—a bad idea, according to Tanya Kormeili, MD, “This may remove the small ones, but some of the bigger ones have a larger blood supply and may become very painful as you strangulate the skin tag. They are easily removed in the office by a dermatologist.”
