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.

Skin tags can occur almost anywhere on the body covered by skin. However, the two most common areas for skin tags are the neck and armpits. Other common body areas for the development of skin tags include the eyelids, upper chest (particularly under the female breasts), buttock folds, and groin folds. Tags are typically thought to occur where skin rubs against itself or clothing. Babies who are plump may also develop skin tags in areas where skin rubs against skin, like the sides of the neck. Younger children may develop tags at the upper eyelid areas, often in areas where they may rub their eyes. Older children and preteens may develop tags in the underarm area from friction and repetitive irritation from sports.
Skin tags have been linked to diabetes. "We know that diabetics are more prone to them. More research is needed to know exactly why that is scientifically, but there’s some correlation that we observed with diabetes," says Geraghty.
