Are skin warts just ok? does it have to be removed? thanks.

OK. Can stay on.: Warts are caused by a virus. They often go away with time, but sometimes takes a long time. They can be removed if they are cosmetically concerning or if they cause dysfunction , but by no means is removal required.

Warts: Left on its own, a wart will die in 2 - 3 years and fall off. Since it is caused by a virus and looks bad cosmetically, especially if large and spreading rapidly, it has to be removed or burned off.
