HPV This stands for human papillomavirus. More than 100 types can cause warts on different parts of your body: your feet, face, and neck, among others. When HPV infects your private parts -- this can happen to men and women -- it can sometimes lead to cancer. It can live in your body for years, and you might not know it. But a vaccine can help prevent it: Girls can get the shot between the ages of 9 and 26, and boys from 9 to 21.
