what is a wart on finger

A wart on a finger is usually a small, rough skin growth caused by a virus called HPV. It often looks grainy, may have tiny black dots, and can appear on the fingers, hands, or around the nails.

Quick Scoop

• What it is: A common wart is a non-cancerous skin bump that most often shows up on fingers or hands.

• Why it happens: It develops when HPV gets into the skin through tiny cuts, scrapes, or breaks.

• What it looks like: Rough, raised, fleshy, grainy bumps; black dots can be visible because of clotted blood vessels.

• Is it serious?: Usually not. Many warts go away on their own, though they can be annoying or embarrassing.

• Common treatments: Salicylic acid and cryotherapy are common options; treatment can take time.

When to get checked

See a clinician if the spot is painful, bleeding, spreading fast, changing color, or you are unsure it is a wart. If you want, I can also help you tell a wart apart from a callus, blister, or skin tag.
