The human papilloma virus can be of over 60 types, and some of them cause infections of the upper layer of the skin, known as warts.
In fact, it attacks the skin through small scratches, leading to rapid cell growth, and eventually causing warts.
In most cases, warts appear on the fingers and hands, but they can also be found on the abdomen, under the breasts, on the neck, on the eyelids, armpits, and in the groin. They are in the same color as the skin or a bit brighter. Warts are not a serious health issue, but people prefer to remove them, due to their unpleasant appearance.
Middle aged people are the most prone to warts, and their size increases with age. The major factors for the development of warts are obesity and genetics.
