Do all warts cause cancer?

Warts are caused by human papilloma virus (HPV) infections. There are many different HPV strains. Most warts develop from non-cancerous HPV infections and never progress from a wart to cancer. However, some HPV strains cause cellular changes that do progress to cancer, often without forming a visible wart. Areas of the body most susceptible to HPV related cancer are the mouth, anus and the cervix in women.
