What are Skin Warts?
Warts are small, noncancerous growths that appear on the skin due to infection with the Human papillomavirus (HPV). The virus triggers extra cell growth that causes the outer layer of skin over the area to become thick and hard.
Warts can occur anywhere but are most common on knuckles, fingers, elbows, knees, or any area with broken skin. They are stony hard, and white.
Who Gets Them?
Not everyone who comes in contact with HPV will get a wart. If you cut or damage your skin in some way, it is easier for the virus to take hold. This is the reason, people with chronic skin conditions like eczema, or who bite their nails or pick at hangnails are more prone.
