What should you know about thick skin tag?

Skin tags, also called acrochordons, commonly arise where skin rubs against skin or clothing, such as the neck, underarms, eyelids, groin, or beneath the breasts. A tag may become thicker, irritated, or darker after repeated rubbing or twisting. Its appearance alone cannot confirm that it is a skin tag; a wart, mole, inflamed growth, or another lesion can look similar.

A clinician may inspect the surface, attachment, colour, and surrounding skin. Do not tie off, cut, or burn a thick growth at home, because bleeding, infection, and an incorrect diagnosis are possible.

Arrange a skin assessment if the growth is new, catches on jewellery, bleeds with light contact, or repeatedly becomes sore. Until then, reduce rubbing with loose clothing and keep the area clean and dry. Photographing a changing lesion can help you describe its development at an appointment.

If the diagnosis is a skin tag and removal is wanted, a dermatologist may discuss snipping, freezing with cryotherapy, or controlled heat through electrosurgery. The choice depends on the size, stalk, location, and whether the lesion is irritated. Read about [Cryotherapy (Lesion Removal)](/treatments/surgical-dermatology/cryotherapy-lesion-removal/), [Electrosurgery](/treatments/surgical-dermatology/electrosurgery/), or [Skin Tag Removal](/treatments/surgical-dermatology/skin-tag-removal/).

Seek prompt medical review for a lesion that grows quickly, changes colour or outline, develops persistent crusting, or bleeds without clear friction. Arrange urgent care for bleeding that does not stop with steady pressure, spreading redness, marked swelling, or severe pain. These signs do not identify a cause by themselves, but they should not be ignored.

Could this be a skin tag or another type of growth? Does its thickness or attachment change the removal options? Should it be examined under magnification or tested after removal? How should I care for the site, and which changes should prompt a follow-up?
