I've been trying to find out how to get rid of a wart on my finger.

The first step is to make sure you have the right information about what a wart is and how it forms. A wart is a benign tumor that grows on the skin or in the mucous membrane. It's caused by a virus called HPV, which can be spread through direct contact with an infected person, such as sharing items like towels or toothbrushes. Warts are usually painless but can cause discomfort when they're irritated or become larger. They can also be contagious if left untreated.
