One final cost is pathology to determine if the mole is cancerous or precancerous. This isn't usually necessary if the mole has been there a very long time. If the mole is new, has changed recently, or has other suspicious features like bleeding, your health insurance should cover the cost of removal and pathology. If you don't have insurance or if you prefer to have a mole sent even when it's being removed for purely cosmetic reasons, then pathology will cost an additional $125-200.
Dermatologists say nay: The tags are almost never cancerous and don’t need to be removed; in fact, they’re (almost!) always benign. And while many people opt to remove them due to discomfort or for cosmetic reasons, there is no harm in leaving them be. There are extremely rare exceptions to this rule: In one study, two patients with known basal cell nevus syndrome (BCNS) were found to have multiple basal cell carcinomas that resembled ordinary skin tags. “There are rare cases where skin cancers, such as basal cell carcinoma, squamous cell carcinoma, and even melanoma, can mimic a skin tag,” says dermatologist Avnee Shah, MD. “Going to a board-certified dermatologist assures a trained eye is examining the lesion and determining the risk of a more harmful condition masquerading as a skin tag.” To be safe, if any tag is growing, changing color, or bleeding and itching, it’s definitely time to see an expert.

And speaking of cancer, it’s generally not something you need to worry about with regular old skin tags. Dr. Farber says that, “If anything changes quickly, is unusually painful, or concerns you, it’s worth getting it examined to confirm it’s a benign skin tag …. Skin tags tend to grow very slowly. Any growth that changes quickly is a reason to get examined by a dermatologist.”
