Warts have become a common problem among adults as well as children. Classified within the Human Papilloma Viruses, though harmless, warts have the capability of spreading to all the parts of the body. They can occur anywhere - skin, mouth, genitals, rectal area, etc. Also referred to as skin tumors, they can be classified into various types, such as common warts, foot warts, flat warts and genital warts. Warts appear as rough elevations on the skin, generally on the fingers, elbows, knees, face and scalp. Primarily caused by virus infection, warts can also result from defects in the proper development of skin surface, in certain areas. Warts can, however, be treated using home remedies.
