By Mayo Clinic staffHPV infection is a condition contracted from one of a group of more than 100 related human papillomaviruses (HPVs).
Each type of HPV has the potential to cause an abnormal growth on a particular part of your body — genital warts and other lesions on or near your genitals or anus, common warts on your hands, plantar warts on your feet, and warts and other lesions in your mouth and upper respiratory system.
HPV infections are common. About 20 million people in the United States have HPV infections that can cause genital warts and related lesions. Some types of HPV infection can cause cancer, such as cervical cancer, but most HPV infections don't lead to cancer.
