what is a wart on finger

A wart on the finger is a small, grainy skin growth that occurs most often on the fingers or hands. They are caused by the human papillomavirus (HPV), which enters through small cuts in the skin and causes an overgrowth of cells, making the outer layer of the skin turn thick and hard, and a raised, dome-shaped wart eventually forms. Common warts usually occur on the fingers or hands and may be small, fleshy, grainy bumps that are rough to the touch and sprinkled with black pinpoints, which are small, clotted blood vessels. Warts on the hands can be uncomfortable and embarrassing to have, but they are not cancerous. Some people can more easily get warts, and they can spread. While warts are generally harmless, they can be painful or embarrassing, and if they are, removal is an option.
